Wireless quit with no warning or reason -- need help re-establishing it
I have an Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01), according to my system. When I first got Ubuntu, about a year ago, I had a devil of a time getting it rolling. But I finally managed, using wicd. It worked well for a while, despite having to go through a manual reset every time the kernel was updated.
However, about a week ago, it suddenly ceased for no explicable reason (in the midst of browsing, no less), and now it cannot find any wireless networks whatsoever. The manual reset procedure was ineffective. I've basically been on network cable for a week, and not only is that annoying just around the house, that's really not going to fly when I visit my parents for the holidays. They have a wireless router, but it is useless to me if my machine can't detect networks at all.
I therefore need assistance in getting my wireless up and running again. If there's some sort of flaw in my wicd, I have no problem whatsoever in finding another methodology. Tell me how to get whatever data you need, and I'll cut and paste anything you want to know about my system.
Word about interaction: I'm familiar with most computer concepts, I can follow a basic discussion, but when it comes to actual programming, I make a good user. I only know what little about Ubuntu commands I've had to pick up, and most of that is pretty rusty. So feel free to translate any instructions into Captain Dummy talk. However, I have been talked through things like this before, so I'm not a total newbie to the ideas we're discussing, just the actual practice.
