Help with "DNS not responding" problem(Windows 7)?

[Dennis]

I need help with this problem I am running Windows 7 and when I try to connect to the wireless network(s) that are installed in my laptop I can't and when I run the troubleshoot I get the "DNS not responding" message and EVERYTHING I try doesn't work! I've Googled it and everything I read doesn't help. I put in Google DNS and others and it doesn't helped. Can't find a Microsoft Fix it for it. Cleared the DNS Cache EVERYTHING!! This happened before and lasted a while but either I fixed it and I forgot or it fixed itself I'm not sure but any helped is appreciated P.S. it's a WireLESS problem not wired. The apdaptor drivers are up to date and all
