I'm running Windows 7 beta 64-bit build 7000 on my desktop. Everything worked OK up until this morning, when I started my computer. I couldn't access the Internet. So I uninstalled my network card driver (Atheros AR8121/AR8113 version 188.8.131.52) and reinstalled them. Now it works. Very annoying though; I apparently have to do this every time I start the computer. Is this a known issue? I haven't found any newer drivers for the network card, and I don't even know if that would help. My friend has a similar problem, and he has to reinstall the drivers on every startup as well. Will updating to a newer build solve this? I'd really like a solution to this problem, or it might just be enough to make me go back to XP until Windows 7 is released. *edit* Seems the problem just disappeared. Nevermind.
