Last night my wife's laptop couldn't connect to the internet. Error message was DNS servers not responding. I unplug power cables and Ethernet cables from cable modem and router (WRT54GL DD-WRT). That didn't seem to work. Today, she was able to get on certain text heavy websites. The WiFi icon said that she had internet access, but still very limited access and slow. I try DNS Release from router's setup page and DNS Renew. I also tried to release and renew through command prompt, but nothing has worked. I can get full access if I bypass the router and connect to my Desktop. Is my router dieing?

Here is my Desktop's ipconfig /all when connected to the router:

From the ipconfig the router seems to be working for this machine anyway.

Have you tried performing a full reset using the reset button on the router?
Hard Reset (aka 30/30/30 reset):

The following procedure will clear out the NVRAM and set dd-wrt back to default values:
## With the unit powered on, press and hold the reset button on back of unit for 30 seconds
## Without releasing the reset button, unplug the unit and hold reset for another 30 seconds
## Plug the unit back in STILL holding the reset button a final 30 seconds (please note that this step can put Asus devices into recovery mode...see note below!)

This procedure should be done BEFORE and AFTER every firmware upgrade/downgrade.
