Wireless network with random DNS issues.  Not sure if hardware or software.....

Here is the short... I have 3 machines. All wireless. 2 xp 1 vista. All were fine until about 2 weeks ago. I was running a linksys G router w/ DD-WRT open source firmware. I have been running it for some time. I bought the Vista laptop on the 7th of may and used it on the network fine for a couple of weeks. Then things went south. Basically, any of the computers will randomly stop accessing websites by address. I can enter ip address and they work fine. My isp told me I had a DNS issue, because they were able to see my router and connection was fine. So, I could release and renew the router IP and it would work again for a little bit.... the cycle continued. I broke down and bought another router. SAME ISSUES. I have anti virus on all computers and have scanned them with no issues. I turned off all firewalls and security on routers.  Not everytime, but it seems to conicide with one of the computers joining the network after reboot, sleep, etc.  I even reformated the Vista machine, thinking it was the problem. I am lost.

Any help would be appreciated. I know you will need more specific info, and will gladly share, but figured we needed a direction to save from to much info.  I work from home and am about to pull my hair out!!

THanks in advance!
