Every time I restart or turn on my ASUS U36JC laptop (functioning on Windows 7) after shutting it down, I cannot connect to any WiFi networks because it tells me that no connections are available, when I am 100% positive that there ARE networks. I temporarily address this issue by going to Start >> Device Manager >> Network Adapters >> Highlight "Atheros AR9002WB-1NG Wireless Network Adapter" >> Uninstall >> Scan for hardware changes (which reinstalls the adapter) >> Problem temporarily solved, but passwords for wireless connections I've previously connected to are wiped out. This isn't solving the problem because every time I shut down my computer, the issue comes back when I turn it back on. I am a complete dummy when it comes to these hardware / software things. Could someone help? Thanks so much!
