I got my XO as part of the G1G1 program, way back when. The wireless network card has always been flaky. I would said, typically only 10% of the time can I see any SSIDs. Also, ifconfig -a from the terminal generally doesn't show eth0, only the loopback.
When I look at "About My Computer", under Wireless Firmware it says "Not available". I have upgraded many different times over the years and I'm currently running 860, I believe.
Long story short, I'm pretty sure the wireless adapter is fried. What are my alternatives? I read a bunch of the wiki hardware pages and I don't see anyone talking about how to replace the wireless adapter. Is that not possible? Can I use an external usb wireless adapter?
