I am operating Windows 8. I used to be able to see all the available wireless networks. Now nothing appears but my computer still connects to my home wireless network - a Netgear product. How do I get the available wireless networks to appear?

Hi,

For this problem, generally speaking, you can try to reinstall the wireless card driver for test to fix this problem.

On the other hand, According to your description, this can be network automatically connection setting problem.

Next time when you connect home wireless network, right click the connection and choose to forget the connection for test.
