Windows 7 DNS server is not responding
I got a new laptop a couple of weeks ago (dell vostro 3300, core i5, windows 7 professional 64-bit, DW 1501 Wireless-N WLAN half mini card) and it worked fine. A couple of days ago it stopped connecting to the internet through ANY wireless network. I manage to connect to the network but not to the internet.
After diagnosis it gives me the following message:
"your computer appears to be correctly configured but the device or resource (DNS server) is not responding"
At home I connect through a wireless router. Now, my desktop can connect through my router to the internet and my laptop connects through the router ONLY IF I connect it physically to the router (through the network connection).
I tried the following steps:
-reinstall wireless card drivers
-Check for malware and viruses (im using trend micro)
-shutting down the firewall
-restarting computer (many times)
- all possible diagnoses supplied by windows 7
-CHECKING THIS AND OTHER FORUMS.
This problem seems to be quite repetitive with windows 7 for some reason. I did not find any good solution.
I am only somewhat computer literate, so I did not really change any advanced definitions (besides some which were suggested in different forums).
I hope someone can help me here - this is very frustrating.
Thanks !
