Motorola NVG510 help page for AT&T U-Verse users

This page is intended to help users of the Motorola NVG510 Modem/Router identify and solve some issues that I (and others) have encountered.

It has a list of questions and answers to the most common problems after the intro part.

Given I cannot longer attend to specific user requests, I suggest using Jordan's app to solve most of your problems quickly. It's free, and Jordan is there to provide support and answer questions in case of problems. I do suggest you consider donating to Jordan for his work.

You can also read more details in this blog post.


The two most common problems are:

  1. Webpages do not load fully. This problem will happen in any browser, not just Safari, Firefox etc. The problem is not in your computer or browser. It is within the NVG510 (despite what AT&T might tell you). To fix it, see answer number 4 in this post.
  2. Frequent line drops and disconnects - there can be several issues creating this problem. One solution is to ask AT&T to lower the speed of your connection. If it solves the problem, ask them to send a technician to test the quality of your line, or email me and I might be able to help.


[Updates 1/6/2014]:

1. This is by far the most visited page on my site. It receives over 8,600 visitors a month. That is crazy!
2. It is more than 2 years old, and AT&T users still have problems.
3. Unfortunately I cannot attend to users comments anymore, so I have disabled the commenting option - if you follow the instructions in this post carefully, it will solve your problems - really.
4. I highly recommend using Jordan's app - Jordan has been very helpful in solving NVG510 problems, maintains a few active pages with details and provides excellent support.

[Updated 6/3/2012]:

  1. Six months passed, and users are still having issues. AT&T is weird...
  2. My WordPress insists of constantly changing the pagination of this page - apologies.
  3. The PayPal donation button is back - please consider using it. 🙂

[Updated 2/7/2012]: Now added instructions on changing specific DNS settings on computers. See Answer 4

[Updated 12/15/2011]: Added note about IPv6 issues

[Updated 1/21/2012]: Lots of comment Spam. If it will continue for long, I will be closing commenting. Just email me if you really have issues, or go through the comments and answers in this post

[Updated 1/31/2012]: Somehow, the bridging instructions I wrote were completely wrong and from a previous version of this post. I'm surprised it even worked

If you have suggestions on how to improve this page or perhaps you have found other issues or solutions, please feel free to contact me through the details on the "About Me" page.


  1. What is the Motorola NVG510?

The Motorola NVG510 is a combined ADSL2+/Router provided by AT&T for its U-Verse High Speed Internet Customers. It appears AT&T have been providing these modems since around August 2011.

  1. Where can I find the Manual for the NVG510 Router/Modem?

Follow this link to download the manual from this site, with the following disclaimer:
At this time a manual is not available on AT&T's website or motorola website. However, a manual was submitted to the FCC as part of the approval process.
It mostly fits the modems sent to consumers homes, but some interfaces (mainly the command line interface) seem to be disabled.
It can be downloaded from: using Grantee Code GZ5 and Product Code NVG510. Under "Display Exhibits" choose "Detail". The manual provided on this site was printed from that link. Copyright belongs to its respective owners.

  1. How do I access the modem's configuration page?

Open a web browser and type in the modem's IP address and press enter. By default it is
This should display a page similar to this:

NVG510 Main page [click to enlarge

  1. My web pages partially load (e.g., not all images load), or the modem shows a message that websites cannot be reached. What do I do?

This appears to be a main issue with the NVG510 - its DNS settings have an issue with waiting for response from the DNS servers (they give up too fast). To see if this is an issue with your connection, go to the "Diagnostics->Logs" tab. You will need to enter the device access code which can be found on a (yellow) sticker on the modem.
Go over the log. If lines similar to the following appear, then you are having the DNS issues other people have:

2011-11-24T16:53:13-08:00 L3 dnsmasq[2478]: no responses from nameserver ''
2011-11-24T16:53:13-08:00 L3 dnsmasq[2478]: no responses from nameserver ''
2011-11-24T16:53:13-08:00 L3 dnsmasq[2478]: nameserver '' is now responding
2011-11-24T16:53:13-08:00 L3 dnsmasq[2478]: nameserver '' is now responding
2011-11-24T17:22:56-08:00 L3 dnsmasq[2478]: no responses from nameserver ''
2011-11-24T17:22:57-08:00 L3 dnsmasq[2478]: nameserver '' is now responding
2011-11-24T17:23:09-08:00 L3 dnsmasq[2478]: no responses from nameserver ''
2011-11-24T17:23:10-08:00 L3 dnsmasq[2478]: nameserver '' is now responding

Until AT&T solves this issue on their DNS servers or by updating the NVG510, there are two possible workarounds that seem to work well:

(a) Manually enter the DNS server details in every device and computer that accesses the Internet through the NVG510. This is a little burdensome.
This is done differently for a Mac or a PC. Specific instructions for each operating system can be found here.

(b) Force the NVG510 to act as a modem only ("bridge" mode), and setup a router after it to handle DNS, address distribution (DHCP) etc. If you have a router (such as a residential WiFi router), this process is very easy.
Then, in this router, set the DNS servers manually. To see how to do all of these, see question 6 below describing how to force the NVG510 into "bridge" mode.

Two things to note:

(a) The DNS server addresses to use appear in the log above, and also in the NVG510 Broadband->Status menu as "Primary DNS" and "Secondary DNS".

(b) The DNS servers themselves are actually fine. However, from my experience (in the SF Bay Area), using Google's DNS significantly improves the network performance. To see how to use Google's public DNS servers, see here. The IP addresses are and If you want to check the performance of your connection, use

  1. Some of the websites I go to are stuck with a message from the NVG510, even though other websites work fine.

To fix this issue, clear the web browser's cache. In Google Chrome, this will be in Preferences->Under the Hood->Clear Browsing Data and make sure that "Empty the Cache" is marked.

  1. I want to use my own Wireless Router instead of the NVG510 - Can I bypass the modem or put it into "bridge" mode?

Formally, the NVG510 does not seem to have a simple bridge mode configuration. Luckily, the nice people at the AT&T forum have found a workaround. Making it work requires configuring both the NVG510 and the router manually.

Here are the details:

On the NVG510:

1. Under "Home Network->Subnets & DHCP":
- Device IPv4 Address: (this is the default)
- DHCPv4 Start Address:
- DHCPv4 End Address:
(This tells the NVG510 to only allocate one address to a device connected to it)

2. Under "Home Network->Wireless"
- Wireless Operation: Off
(Since you will be using your own WiFi router)

3. Under "Firewall->IP Passthrough"
- Allocation Mode: Passthrough
- Passthrough Mode: DHCPS-fixed
- Passthrough Fixed MAC Address: <MAC address of the home router>
(You can find your home router MAC address on the home router's status page.
Make sure to enter the WAN MAC address).

3. Under "Home Network->Configuration", change IPv6 to "Off", unless you know how to configure IPv6 to work with your router. This will save you some issues in the future.

On the Home Router

1. Make sure the home router allocates DHCP addresses on the LAN on a different range than For example, will work (with a subnet mask of or will work (with a subnet mask of

2. Tell the router to use a fixed WAN IP address (to not use DHCP to get an IP address from the NVG510). Then use the address from the NVG510 configuration page under "Broadband->Broadband IPv4 Address" as the WAN IP address, as the subnet mask, the address under "Broadband->Gateway IPv4 Address" as the gateway address and the DNS server addresses from question #4 above as the primary and secondary addresses.

Note: from my experience, Google's DNS servers ( and perform better in the SF Bay Area.

  1. Everything worked great and then suddenly stopped, what happened?

AT&T may have turned on IPv6 on your line, and it messes up the "bridging" mode. To check this, look under "Broadband->Status". If the IPv6 status is "Available", this may be causing the issue.
The solution is to go to "Home Network->Configure", and change the IPv6 option to "Off". Then restart the NVG510 and router.

  1. Why did you create this page?

I was a little frustrated with looking online for all the answers and finding the details scattered all around. Frankly, I'm surprised AT&T doesn't use their own forums to identify such issues, since they seem to be pervasive.
I hope this page has put some order into all the issues. If you notice anything wrong or have any suggestion, shoot me an email (details are in the about me page).

I created this page while being a grad student, and PhD students always have use for more Pizza, or books, so please consider supporting grad students at Cal, this way they can find a cure for cancer, or fix AT&T blunders. 🙂

  1. I have deeper issues, how can I solve them?

Use the AT&T forums and the BBR forums. People there are really helpful. Try to make sure to post your Modem's log (see above for how to access it), and also screenshots of your configuration. If all else fails, contact AT&T Tier 2 Support.

    Hello. I got this modem yesterday. A storm came through the town I live in and I had a power surge. Everything was fine, had everything in a couple of surge protectors, everything except the modem ( which was plugged in to a S.P) now it wont even power up at all. But there is a very very dim green light on the power label. Any ideas? I've tried the reset button but nothing. Please dont tell me I got to have a tech support here again.

  2. Dennis says:

    I have a Motorola NVG510 with U-verse, and trying to setup a Belkin N150 router, But nothing works.. Can you help me!!! Thank you !

  3. Karl Edmonson says:

    So, I'm not very techie, but I can unplug and plug my modem back in. For the past several months, I've been getting a red service light, even though the broadband light (and connection) stays green. I am losing the ability to connect several times a day (and I work from home, so it's an issue). I've had 3 AT&T techs come out, and finally this last one said there is an issue with software for the Uverse modem, that AT&T is aware of, but waiting for Microsoft to issue an update, which has no timeline. Has anyone else been told this? I'm considering calling AT&T sales and getting some sort of reimbursement since I'm paying for a constant service that they can't seem to provide. Anyone had any luck with that?

    What router can I use to replace the nvg510?

  6. cory z says:

    i was playing xbox and it said mtu error what does this mean

  7. Jade says:

    Your instructions were really helpful. I was able to use the old 2wire 2701hg-b as the router for LAN connections but cannot seem to get the wireless to do so. It pulls up the old 2wire error page saying that there is no broadband connection. Do you know of any way to disable to 2wire's ability to look for a broadband link and allow for wireless access?

  8. jonah says:

    A clarification for Airport Extreme or Express users...

    I found this bit of the instructions confusing:

    "2. Tell the router to use a fixed WAN IP address (to not use DHCP to get an IP address from the NVG510). Then use the address from the NVG510 configuration page under “Broadband->Broadband IPv4 Address” as the WAN IP address, as the subnet mask, the address under “Broadband->Gateway IPv4 Address” as the gateway address and the DNS server addresses from question #4 above as the primary and secondary addresses."

    Open airport utility, select your router, and click edit. Then click the internet tab.
    Under "Connect Using:" select "Static"

    For the "IPv4 Address" use the address from the NVG510 configuration page under “Broadband->Broadband IPv4 Address”

    For "Subnet Mask" enter

    For "Router Address" use the address under “Broadband->Gateway IPv4 Address” in the NVG510 configuration page.

    For "DNS Servers" use Broadband->Status menu as “Primary DNS” and “Secondary DNS”.

    is it possible to disactivate bride mode on the nvg510 router
    i accidently turned wireless operation off and i dont have another router

  10. switz says:

    Hello Ron,

    Great information! I have been so frustrated with ATT as they gave me five static IP's but there is no way to use them without keeping my internal LAN. My question to you is: Do you know of a router that I can add that will allow multiple static IP assigning to the LAN/WAN? if so, then I can keep my internal network and assign servers/cameras to the outside WAN. Thanks in advance!


    • switz says:

      Never mind...I gave up on AT&T. This is the stupidest thing I have seen: you just can't do a 1 to 1 NAT on the damn Motorola modem. Staying with Comcast. Good bye to U-Verse DSL.

  11. Michelle says:

    HELP! 2 or 3 questions... I have DSL, not U-verse. Can I use this thing? It shows a DSL/ broadband input on the back. And is it a modem or a router or what? I am not tech savvy. I have a shitty modem that always drops off and a net gear wireless router.

  12. Joel Goldman says:

    We have ATT u-verse with the Motorola NVG510 modem router. In one or more places in our apartment we have such a low signal that often results in a message that says I'm not connected to the Internet, etc. Is there an easy way to increase this amplification? I have been on websites for antenna type products, but cannot tell if any of them are compatible with the NVG510. Obviously you can tell by this email that I am not a techie. Thanks so much

  13. I have an NVG510 with two wireless lap computers and one Brother wireless printer. My wireless laptops work fine. My brother printer MFX-8890-DW is not recognized by the computers. I've deleted the drivers and tried to reload. Because the computers do not recognize the printer, I cannot reload. The NVG510 is connected to Broadband to the telephone jack in the wall and the telephone line on my telephone which is not wireless in the main unit and has other telephones connected that are wireless. What can I do? Help! Elaine

  14. Nick says:

    Okay, I've got a Lynksys WRT54G and I'm trying to set up bridge mode, but it will only serve DHCP clients on the same band as it's own IP address, and if I change the IP address to something other than the NVG510 won't serve it. Is this just my luck on the router or is there a way around the part that you set your router to another band?

  15. TRex Customz says:

    Hopefully you can help me with my NVG510 and u-verse
    I currently have a 8 analog camera system running to a dvr. I can view the images on my phone if I am connected to the host network. I can not how ever view them outside of the network.
    I have this same system at my house with verizon fios and I had no issues getting it up and going but this u verse is giving me a hard time.

    any help would be great!!

  17. Jerry says:

    Thanks for posting the instructions. I've followed them but no luck. I can't get to my "real" wireless router login/status page in "Passthrough" mode. I'm pretty sure I have the right IP address because I can get to it when connected directly to a laptop. But when I connect to one of the 4 ports on back of AT&T's Motorola NVG510 my browser keeps timing out with "The connection was reset" etc. Any further help will be much appreciated.

  18. Kyle says:

    I have a HP MediaSmart Home Server, I have been trying to setup the remote access (for 6 years), but it errors out when trying to configure the router using UPnP standards. I cant find anywhere in the system-summary page for the router on how to configure the UPnP settings. I have read that it is hard to set up using this router but can be done. how do I go about setting it up so the remote access can work.
    I have tried the old 2wire dSL gateway, and the single computer modem still dosent work back before I upgraded to uverse

  19. Rob says:

    I want to switch from a Netgear modem (currently working fine) to the NVG510. However, I cannot get the NVG510 to connect (with Diagnostic checks, the line is there but Broadband is out and Authorization and PTM fail). I suspect an authorization problem whereby the line wants me to enter my Network User ID and password, but I cannot find ANY place within the NVG510's setup (Web Management Interface) to enter it. Other Motorola modems running essentially the same setup software have a spot to enter this, but apparently not this one? I did a full reset on the unit, thinking it might force it to ask me when I opened the WMI, but no luck. Any ideas?

  20. Eric Lalonde says:

    This page is incredibly helpful for NVG510 owners. It is also trending up in the google search results for 'motorola nvg510 ip passthrough'. Thanks for publishing this.

    • Eric Lalonde says:


      Using IP Passthrough I have no problems with port forwarding from the internal router to the appropriate LAN machine. Put another way, the NVG-510 is correctly forwarding all WAN-initiated connections to my internal router, which then handles the port forwarding according to my defined rules. So IP Passthrough works for me out-of-the-box using the instructions defined in this document.

  21. RisiL says:

    If the Moto NVG 510 is a ADSL2 modem and a router in one box, should it not be possible to replace it entirely with another modem/router? Or, is there something proprietary in the modem that does not allow using some other device?

    For example, NetGear makes some excellent devices that provide reliable DSL modem functionality and wired and wireless routing. For example, D6200 or D6300 are configurable for ADSL* and VDSL.

    Hey Ron. I just got bitten by the same bug as you have described here and I thought I might pass along my notes. I don't like the idea of having to remove all my cookies and browsing history each time I loose my connection. It kills the browsing experience. So I think I have a more focused attack. Anyway, here are my notes and my assessment of the situation

    Occosionally, there will be a delay between the nvg510 RG and the DNS servers. When this happens the following statetements are visiable in the modem logs.

    This indicates that there was an outage and a loss of internet connectivity

    When this happens, the modem's proxy server appends /cgi-bin/redirect.ha/ to the end of each and ever URL request which causes the familure error page below to be displayed.


    WARNING: Potential Connection Issue (Message ID: NAD-2902)

    The Motorola NVG510 device has detected potential problems with your DSL connection which may impact your service. This problem is often caused by a phone or other device which is connected to your phone line (such as a fax machine, satellite receiver, alarm system or medical monitor) that does not have a DSL filter.

    Please check that all telephone equipment is attached to a DSL filter and that all filters are properly installed (e.g., are not installed backwards).

    Click the "Do not show" button to permanently disable this warning in the future.

    Click on the "Continue" button to notify you in the future if this situation persists.


    At this point, you are given two options, "Do not show" and "Continue" as far as I can tell, neither button does anything useful.

    Here is what I see is happening behind the sceens, the RG dropps/updates a cookie in the browser which I believe is to indicate that the proxy is down on the RG. That cookie is then read on each and every subsequent request which causes the request to get appended with the /cgi-bin/redirect.ha/ displaying the error message again. This also causes another side affect in that all those requests are logged in the browser history so that each subsequent time you try to browse to a site that had been previously redirected to the RG error message (/cgi-bin/redirect.ha/), the browser thinks you want to go there again.

    The common suggestions I have seen for this problem are to clear out cache, cookies, and browsing history which is a big inconvience since you loose a lot of your browsing experience when you do this. My suggestion which is a bit more involved but less intrusive. Keep in mind that I'm still working out the final details on the implementation. But the gist of it is to only remove what is absolutely necessary.

    Step 1, Clear out the bad cookie.

    In Firefox, Find the "remove individual cookies" link under Options | Privacy tab
    Then look for any cookies that look like and remove them completely

    Step 2, Clean up the browsing history.

    In Firefox, "Show All History" under the History menu
    Enter "cgi-bin/redirect.ha" into the search bar and then delete any results that are returned.

    This should minimize the impact of the outage.

    Now how do you keep this from happening in the first place
    1 - ATT&T and Motorola can fix the firmware and increase the timeout for response from the nameservers or allow it to be configurable from the admin pages

    2 - Allow users to configure the DNS nameservers so that they point to ones that have quicker response

    3 - Turn off the redirect completely and just accept that users have seen 404 errors in the past and just let them figure it out.

    There are other solutions out there that mask or circumvent the issue but don't really fix the problem. not everyone wants to have to use a second gateway to handle DNS and not everyone is ready to break the warentee and hack into the firmware. But they are solutions.
    Try my workaround above. It probably needs to be tweeked some but I have had some positive results. If it can be proven, then it would probably be possible to script out or create a plugin that will do it automatically.

  26. Joe says:

    Thanks so much! This seems have gone a long way toward fixing really frustrating routing problems I've been having. Interestingly, instead of just "impatience" in getting response from DNS servers, the error logs from my NVG510 were quite varied (largely incomprehensible to me though) -- I'm happy to share if you're at all interested. There was really bizarre performance too with many websites continually kicking me to the ATT error/troubleshooting page (even after clearing my browser's cache) while other tabs in the same browser were obviously still connected (notably Gmail). This might have something to do with the Google servers being better, as you mention?
    Anyway, I went ahead and followed your directions to set up the (crappy) NVG510 as a bridge to my D-Link router, and things seem to be working MUCH better. Thanks for doing ATT tech support's job for them. You should send them a bill.
    I'm so grateful that, as a Stanford alum, I'll even forgive the fact that you're at Cal and chip in for your pizza fund. (I enjoy the Stanford-Cal rivalry, but I don't take any of it seriously/personally.)

  27. Joe says:


    Is there a way to turn an ethernet port into a WAN port? so I can use it as a router and connect it to my modem?

    There is a lot of people like me who paid for a NVG510, switched provider and are stuck with a useless router, on top of that having to pay for another router sucks!

    I appreciate any guidance,

    ATT just changed my modem from a 2WIRE to an NGV510. I have a Fitbit Aria scale that worked fine with old modem. Set up of scale for network and WEP is through iPad or other wireless device. Set up fails just after the modem has connected with the scale. No tech support is available from Fitbit or ATT. Last clue is that scale needs 802.11b and router may be set to 802.11n only. ATT cannot tell me how to find this on the modem screen. I would appreciate any help towards figuring this out. Thank you, Bill Hoffmann

    My NVG510 arrived just days ago, with software version 9.0.6h2d21. I want to use my dd-wrt router like I used to be with standard adsl and I read the posts above already. Wonder if the method you described above or to use cascaded router option. Thanks very much for the post!

    Hey there,
    I have a netgear wireless router (N600 WNDR3700) that I am trying to add behind my ATT Uverse NVG510. Problem: cannot get to the web interface of the netgear. Any suggestions? Right now I have the netgear hooked up to the NVG510 via a lan connection. All pc's are hooked up to the netgear (wireless or wired) and all can access the internet no problem. I just cannot get to the netgear interface to configure it as prescribed in item 6 above (Ron's recipe). I have made no setting changes to anything. Help please...I am not the most network savvy...admitted.

  35. ROI says:

    Just got a new ATT Motorola NVG510 with Uverse upgrade. This is a Business account and I ordered 5 Static iP's for 1 to 1 NATing. Been on the phone with ATT & we are still dead in the water.

    I got the DVR to work on Port 8000 on the Dynamic address but not on the Static iP.

    Any Suggestion will be Appreciated.

    Thank You,

    good sir.
    a few of our computers drop connection randomly (mostly around 9ish, but one drops every few minutes.

    2013-03-09T01:54:19-05:00 L3 sdb[307]: Wi-Fi: Client xxx joined ATT952.
    2013-03-09T01:56:59-05:00 L3 sdb[307]: Wi-Fi: Client xxx left ATT952
    2013-03-09T01:57:03-05:00 L3 sdb[307]: Wi-Fi: xxx re-joined ATT952 after4 seconds

    2013-03-09T03:39:09-05:00 L3 sdb[307]: Wi-Fi: Client xxx joined ATT952.
    it seems to almost be on clock work (close to the hour change excluding from 4 to 7 but we were out at that time)
    between these are some nameserver ping outs.
    would using a home router fix this problem or is this deeper than that?
    any help you can give would be very helpful and appreciated.

    I want to connect three Soundpoint 335 phones to the NVG510. What wireless hardware is required to connect to the 510? Many thanks!


  38. Mason says:

    i have a nvg510 and am trying to change the ip address, how do i do that with this router??

  39. Tim says:

    I tried switching to the public DNS servers, but they didn't really resolve the problem. Many pages would still fail to load correctly. Those who are brave can check out Earlz NVG510 software exploit to root and hack the modem firmware to manually change the primary and secondary DNS numbers.

    Caution: You will void your warranty and possibly brick your modem. But it did work for me. Check the comment section.

  40. jim says:

    Could you post what the default settings are on the motorola router from ATT , if I want to go back from the bridge mode to the default mode ?

    • Tyler says:

      All you need to do is press the small button inside the tiny circle at the back of the gateway and it will change to factory defaults after all the lights flash red.

  43. Hhogan says:

    AT&T just replaced my old modem/linksys router combo with the Motorola NVG510. On my old linksys router I was able to easily input websites that I wanted blocked. This prevented my kids from wasting hours on "youtube". They have access to the internet thru both their ipads and laptops - but need to connect to wifi thru the home router. I don't want to block these sites through the browser on each device - because they actually need to use their ipads to access youtube at school - the teachers have incorporated youtube lessons into their schoolwork. By blocking access to youtube thru the router - they could not access youtube at home, but could still do so at school. I called AT&T, but the person I spoke with did not think it was possible to block particular websites on the Motorola NVG510. Help?

  44. alex says:

    I'm close, but this isn't quite working for me. I've got all apple stuff. Trying to get AEBS and Airport Express(es) to play nice with NGV510 for Airtunes. I'm stuck on the last step.

    The router (AEBS) under Internet tab has the following settings:
    Connect using>static
    IPv4 address (per instructions used NVG510 configuration “Broadband->Broadband IPv4 Address.
    The AEBS doesn't have GATEWAY ADDRESS field. It has ROUTER address. Is that the same? If so, when entering the address under “Broadband->Gateway IPv4 Address” as the router address, you get the following error: The router address you have entered is not compatible with your WAN IP address.


  45. Michael says:

    Ron I would like to know how many devices can be connected to my Motorola NVG 510 without the speed lowering and and making me lag on my ps3 thank you

  46. Melissa says:

    Thank you for putting all of this together. Explains a lot!! We are trying to connect a Nintendo 3DS to the wifi. The 3ds says the access point's security settings are not supported. Nintendo does not list the nvg510 on their website to help with connecting it. Do you have any insight? B/g/n are all on which is one of the only things we got from Nintendo to check since they don't list our specific modem.


  47. billy says:

    how do i enable upnp on my router??

  48. Jon G. says:

    hey this site is a big help but a query: is it possible to connect both an Xbox 360 AND a PS3 on the NVG510 modem? i've been wrestling with this all day and i cant do it any suggestions?

  49. Tonny says:

    This worked amazingly and it saved me many hours. I've never experienced such a crappy modem.

    I would say in your instructions
    "2. Under “Home Network->Wireless”
    - Wireless Operation: Off
    (Since you will be using your own WiFi router)" Should be last, just incase anyone is trying to configure the settings while still on the lan, and it helps to have all the router and modem information ready before proceeding.


  50. thisguy says:

    Question, regarding the configuration for the Motorola NVG510 and a Netgear router prior to purchasing service from ATT.

    The plan is to use wireless boxes for all of my tvs. By turning off wireless on the Motorola NVG510, won't that prevent the WAP from paring? Or, can I still pair by routing all traffic to my Netgear router?
