Windows 7 DNS server lookup failure

[sebastianfrei]

I bought a new computer about 3-4 weeks a go. I got a ASUS PCE-N10 wireless local are network card and plugged it in. For the first 2 weeks it performed fine with no problems. recently however, i have been getting a DNS server look up fail error. Ill be able to go on the internet and use it, but every 5 minutes or so this will happen. The longer I use the internet the worse it gets. Any ideas?
