I have been Googling this for weeks, trying everything. It appears many people have this problem, and there are no solutions that work.
I've deleted my wireless networks, and then rediscovered them and chose to automatically connect. Done this a few times while troubleshooting. I did what one person said, which he said it's a bug with Windows 7, where you have to uncheck "connect automatically", then restart, then recheck it, then restart. Yes, that works, but only for one reboot. I notice that every network I can see has the "connect automatically" box checked, but the one I connect to doesn't have one at all. And yes I confirmed it's set to auto connect in the properties. I'm not having the problem where the box unchecks itself. I don't have to re-enter my password when I connect to my network at home. I'm not getting any type of errors.
I'm using an Intel 6205 wireless card, and the driver is only months old (newest driver I assume).
This guy is having the exact same problem as me: http://windows.bigresource.com/Win7-...-FUAjUUu3.html
