Laptop can't see any wireless network, but still connects to one

I recently moved and had to re-setup a new wireless network at home. Unfortunately, my laptop can't seem to see any wireless network (the available wireless network list is always empty). There's a non protected wireless network near my home, and even though it doesn't appear in the list, it automatically connects to it. Using my girlfriend's laptop, I can tell that there is about 10 networks in the area (including mine). My laptop doesn't see any of them. I must have triggered something because I never had any problem of the kind before.

What usually works for me is just to going to Device Manager and right clicking on the card and clicking Uninstall. After that all I have to do is click Scan for Hardware Changes. And it reinstalls and works

"Since you aren't getting ANY wireless signals the first thing I would check is that you didn't accidentally turn the switch for the wireless off. Many laptops have a switch to manually turn off the wireless.

If that switch is on then I would make sure the device is enabled in the Device Manager:

Right click on Computer/Manage/Device Manager

Make sure there is no issue with the wireless network adapter."

"follow this steps, maybe a virus change this settings at registry.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Ndisuio

there look for

Start key, value must be hexa 3 (""Start""=dword:00000003)
Tag key value must be hexa C (""Tag""=dword:0000000C)

close registry and reboot.
After boot check networks."
