Windows 7: Wifi Adaptor is installed/enabled but Windows can't detect networks

Wifi Adaptor is installed/enabled but Windows can't detect networks

I got a Dell E6220 with Windows 7 32bits. Our System Admin pushed the new A/V upgrade from Symantec 11 to Symantec 12 and that broke all the network connectivities including Ethernet and Wifi.

I was able to run CleanWipe couple time and get rid of all the Symantec crap and checked the registry to make sure there aren't any Symantec stuff in there.

I was able to re-install the Ethernet adaptor and that got the internet working. But when I un-install the WiFi adaptor and re-installed it. It never really re-established the connection between the hardware and Windows. I un-installed the adaptor and re-installed it couple times but no prevail.

The adaptor's driver is installed properly and it's enabled in the control panel. But there is X mark on the wifi symbol and it says troubleshoot. When I try to troubleshoot it say the driver might not be installed properly.

I also plugged in the Netgear USB Wifi Adaptor and it was able to install it but it's doing the same thing as the built in adaptor.

I restart the WLAN service couple times but still no prevail. The Ethernet is working fine without any issue.

So it seems like the WiFi connectivity/services are messed up in the registry. I would hate to re-install windows. ANY SUGGESTIONS??. THANKS IN ADVANCE.

Didn't you ask the System Administrator to solve the issue for you?

lol I wouldn't have this issue if he configured the upgrade properly since couple other machines had the similar issue. But running CleanWipe to remove Symantec and re-installing drivers fixed the issue and I was manually able to install Symantec EndPoint 12 afterwards without any issue.

Initially both machines weren't detecting Ethernet at all. And the WiFi was able to see networks/connect but with limited connectivity with no internet excess.

Solved it by running cleanwipe to remove Symantec and than removing teefer3 junk from registry. Also had to reinstalled nic drivers. And I was connected. Seemed like the "teefer3" stuff in the registry was over taking windows connectivity.
