DNS not resolving Merlin .390 and ASUS .4561

mrduke

New Around Here
I just discovered this forum 3 days ago when looking for a new router,and I have read and searched a lot. Great information!

The router I chose is the Asus RT-N66R. I love its range and GUI options.

Here's the problem. Randomly every 3 to 12 hours I will lose the ability to reach websites only on the 2.4 ghz signal. The LAN and 5.0 signal work OK. The 2.4 wireless remains connected and shows that it is connected to the internet. I have a small piece of software that says "DNS is not resolving". I originally upgraded to latest ASUS firmware .4561 and then to Merlin build 374.390. Did a full reset and setup of router. Problem still exists. Applying any setting in the GUI clears the problem temporarily. I have contacted ASUS, but so far no solution. Here is part of the log:

I really like the router, but need a solution to this problem to make it a keeper.

Thank you

Sounds like you have a lot of interference from neighbors on 2.4 Ghz.

Set the 2.4 Ghz channel width to "20 MHz"

Then use inSSIDer to help you find the best channel.

Or try channel 1,6 or 11
 
I am already using just 20 Mhz. My nearest neighbor is half mile away. Channel set to auto, usually runs on 6. I did change SSID from ASUS TrioTel 2.4 to ASUSTrioTel2. Will see if that helps, although the 5Mhz was also named with spaces. I don't loose the connection, just can't reach web pages because domain names can't be resolved apparently.

Thanks for the suggestions though. Anymore ideas will be appreciated.

Did you try using google's dns servers?

8.8.8.8
4.4.4.4
