I am running Ubuntu 9.10 on an ASUS eeepc 1000HE, and my wireless card, RaLink RT 2860, is failing to recognize any wireless networks. It was working fine this morning, until I accidentally hit Fn F2, disabling the wireless card. I hit Fn F2 again to reenable it, but it no longer will detect any wireless networks (and other computers in the household do recognize them).

Any help at all will be greatly appreciated!

I googled quite a bit and talked to a human about this but could not fix it. We tried dhclient ra0, which returned

There is already a pid file /var/run/dhclient.pid with pid 2438
killed old client process, removed PID file

I've had this same problem with my Asus Eee 1000HE; I can't seem to find the original link from where I got the original download, but here's an Ubuntu forum link that might be of some help to you:

http://ubuntuforums.org/showthread.php?t=1106542

I note that, according to this link in the Ubuntu wiki, it's a kernel issue that still hasn't seen a fix yet; what's really weird is that whatever the problem is, it seems to hit different Asus Eee 1000HE users slightly differently; not all fixes seem to uniformly work.

Thanks! Oddly enough, my wireless card randomly started working after two days. Totally weird. I didn't reboot or anything. Just sitting there and it suddenly picks up a signal. Oh, EeePC... –  David Zureick-Brown Mar 16 '10 at 18:07
    
Yeah, it's really an odd blemish in an otherwise enjoyable user experience. With this one, all I get is "it's a kernel issue" and has something to do with the wireless hardware, which causes it to Fail in Mysterious Ways. –  T-Boy Mar 16 '10 at 23:06

Go into your bios by pressing f12 at the start of your computer. Then find in the options "ON BOARD WIFI" and enable it. There you go!
