Windows 7 - Can't view available wireless networks

Hi,

since last week our Windows 7 (64-bit) domain computers can't view the available wireless networks anymore. There hasn't been any specific change or update. The wifi networks which were already saved and once connected to, are still working.

Wifi1

Wifi2
We have the problems on all HP notebooks. Please help.

We found out ourselves, only domain-ciomputers were affected. After checking GPO and changing some settings everything worked again.

Tested with network discovery on and off... But this has nothing to do with it.

i guess the screen shot was captured before the issue appeared. if so, there might be a problem with your wifi adapter. please open device management MMC (devmgmt.msc) and remove the current driver of the wifi adapter, after that, restart the system and let the system detect the device automatically. in this situation, the wifi adapter uses the built-in driver included in the system. Please try again to scan the network, can you see these networks?

Have you checked the HP website for any known issues? Also, whenever I have worked on HP pc's/laptops there can sometimes be a conflict between the HP Wireless assistant and Windows Wireless assistant. Make sure one of these is turned off/disabled.

@vernony: I just did this... no success. It used a driver from Windows Update automatically...
So it is still the same situation as on screenshot Wifi1.jpg

i know this problem. there is some setting over there somewhere right now it only shows wifi computers only. you have to switch back to every network. if you ask me where is that setting i don't know. go look at the wireless card settings wireless card section. there is setting over there for that that is why you only see wifi computers not wireless stations.
