Hey, guys. Recently, I've been getting random disconnects in Ubuntu 9.10. I don't know why since I did not have a problem with the previous version or the first couple of weeks while using Karmic. I cannot reconnect without restarting either, even when I provide the correct security key. I have no clue what is causing this, but it's become pretty crippling, as sometimes it happens within five minutes of turning the laptop on, and other times it might come six hours later.
Here's some information about the wireless card:
09:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)
AMD Athlon X2 Dual Core
ATI Radeon 3200 HD Graphics
4 GB DDR2 RAM
64 Bit Ubuntu 9.10
Netgear Rangemax G Router
