I've fixed it before, but we changed the password to connect to the wifi and I don't completely remember how to fix it. Every time I turn on my PC, I won't be connected to the internet as it seems to connect to my old password. I have to go into the network and sharing center and remove my network then start fresh by re typing the password in. After that it will work. I think I fixed it last time through my desktop icon "Asus PCE-N15 WLAN Control Center"
