no connectivity to DNS server

Specs: Windows Vista

Ok, so I have a pc and a laptop. Both connected to the wireless modem. Both computers working good with the wireless modem. One day the laptop just quits loading my pages. Says I have connetion but when I diagnose the problem it says I can't connect to DNS server. Will repair and works for a minute or so then same thing over again. My pc on the other hand works most of the time however everyonce in a while it does the same thing, but for the most part works. So just wondering why all the sudden this starts to happen and what can I do (if anything) to fix it???

It sometimes happens when the computer cannot find DNS it creates a bad IP number.

Are you running 98/XP/or Vista ?

Go into Windows DOS prompt to view your connections:
For 98/ME type: winipcfg /all
for XP ipconfig /all
Then check it against what it supposed to be.

I would clear the present Network configuration by typing:
ipconfig /release.
Reboot and then renew. ipconfig /renew

Windows sometimes confuses the IP when you have 2 PC connected and one day one boots up first, but the next day the other PC boots up first. Repair all too often will not repair the network like we think it should. The only way I found to fix a bug is to start all over (1st release as above said) then Uncheck TCP/IP in both computers, then do one computer at a time adding (check mark) TCP/IP obtain IP and DNS automatically. Connect your 2nd computer and boot it up. Then check mark TCP/IP (as above). Now they should find each other and assign Lan IP's in the order of boot.
