Windows 7 Ult, Windows 8.1 Pro,

This problem seems to be about compatiblity with certain routers and wireless adaptors.
You can read more about it here. Windows 7 wireless network problem: Windows 7 fails to connect using WPA and WPA2

It can also be a router configuration problem, firmware update problem or even a driver problem.

More possible solutions.

Windows 7 Ultimate 64Bit

If it works with XP, and not W7, that would be strange, as the adapter is the same. Are you using the built-in tool or a thirdparty one to connect?

Not unusual at all, this problem is reported at TechNet and isn't occuring on XP or Vista, it's a very common problem.

Hi Guys,

Thanks for the responses. Def. not an issue w/ any of our routers. Only an issue w/ Win7, none of the Vista or XP machines have experienced Wifi problems.

The problem is caused by incompatible driver. Method to resolve as follows:
1. Right Click on Computer and Select properties
2. Select/Click Device Manager
3. Expand the Network Adapters
4. Right Click on the Wireless Adapter and select Update Driver Software…
5. Select/Click Browse my computer for driver software (Locate and install driver software manually.)
6. Select/Click Let me pick from a list of device drivers from my computer (This list will show installed driver software compatible with the device, and all diver software in the same category as the device)
7. Select/Click Have Disk
8. Browse for the compatible Driver (Either on your original driver CD, download from internet Downloads Folder, or your prefer location such as Desktop)
9. Select/Click/Open on the Driver and to install
After the successful l driver installation, connect the internet by using the wireless adapter. Occasionally, you may encounter the problem such as connected to network but without access to internet. Just go to Control Panel/Network and Sharing Center and Click on the “Red X” between the Network and Internet to auto rectify the connection problem.
Cheers! Hope this is helpful.
