Hi: This is my first post, so sorry if I don't know all of the protocol. I just installed Windows 7 two days ago. I have a Toshiba laptop. I'm running Win 7 Home Premium, 64-bit. Problem is, it just disconnected me from my wireless network randomly. Worked fine all day, then just stopped. I reset both my cable modem and the wifi router, to no avail. I'm plugged in right now for access. I ran the troubleshooter and it says "problem with wireless adapter or access point." The adapter I have is an Atheros AR5007EG. (When I look in the system info tab, it doesn't even know what the name of the adapter is -- everything says "Not Available") Windows says I have the right drivers, so I'm not sure what to do next. I sometimes had a wifi connection problem with Vista -- I would just disable the firewall, very bad, I know -- to work around it. So, if someone can help with this, it would be great. I don't quite know all the nuances of how to get to .exe files and things like that, so if there's a less technical way to explain it, that would help! Many thanks!
