How to edit NVG510 to fix DNS problems

Well, I had a nasty adventure trying to upgrade my ATT DSL to Uverse – and by the end I was not able to  get higher speeds.

I spent more for less – especially when i couldn’t load some sites – that was a DNS problem in the router that was fixed with this simple gem…

The main issue you might encounter is that not all websites load, or that pages load partially, with images not appearing or partially loading.The problem is in the NVG510, not with AT&T or your network. For the technically oriented, the problem is that the NVG510 has a short timeout for DNS responses – it gives up before the answer comes back.

    If I choose to use the following suggestion can I use a a Repeater such as the Amped Wireless SR10000 which I have or do I need to purchase a standard wireless router?

    There are two solutions to this issue. One of them is to add a router between the NVG510 and your devices, and set the NVG510 into bridge mode. This is described in answer 6 of the FAQ page. This is the solution I recommend because it does not require changing settings on every device which connects to the network.

    This fix does not work.Your router is hardwired to the at&t server, this fix, cannot re-route your hardwire, sorry, you are stuck with at&t’s servers. Your speed problem is with at&t over selling their bandwidth. You can try running a trace-route before, and after this fix, and at&t’s problem server will still show as the first in line after your modem. There is NOTHING you can do about it, Running a trace-route clearly shows at&t servers dropping packets at an unacceptable percentage, for me personally, the packet loss rate is over 90%, anything over 5% is unacceptable. Good luck dealing with at&t’s customer service, or tech support, neither will have a clue of what your are talking about. The best you can do is file a complaint with your states Attorney General against at&t’s false claims of said speeds, and for over selling their bandwidth. Until at&t updates their equipment to handle what they sell, then we all will suffer. Or you can use another service, of course that will cost more, way more. Good luck in all you do and sorry for your frustration caused by at&t.

      I switched to Sonic DSL last year and it’s been great. Happy to not support AT&T anymore.
