Wifi shows as connected but no internet access.
I have purchased a New dell Inspiron N5050, windows 7, with a preinstalled Mcafee 1 month subscription. The wifi was working fine. But suddenly after a windows 7 update the wifi started showing as Limited access. After messing around with DNS i was able to get it to connect to the wifi network however shows no Internet access but bytes are being transferred. Wen i try to ping the router it shows general failure. I have reinstalled the drivers, winsock reset, i even uninstalled all windows updates with no avail. I also tried to exclude the macfee firewall services from msconfig and tried mostly everything i thought possible still its the same. Any advice is greatly appreciated.
I didn't find the right solution from the Internet.
