I know some people have the 4965agn working fine, yet there are many others who have issues with it. Under Gutsy it always worked, but sometimes I had to poke it repeatedly, and it would give me random disconnects, especially if I wasn't sitting right under an access point. The LED also never came on. I had heard that the real solution was to use a newer kernel, specifically the one that comes with Hardy. Accordingly, I just decided to continue using a borrowed Netgear card until Hardy went final. So last Thursday evening I upgraded to Hardy, which went well, but the LED was still not on, although I did connect at PSU the next day. When I connected it knew what network to connect to (pubnet.pdx.edu) because there was a line in /etc/network/interfaces to use that ESSID. Wifi-Radar and the Network Manager GUI did not show any available networks, nor did the command line.

When I got home Friday and restarted the LED was on (how did that happen?), but the GUIs and command line still did not show any available wireless networks, even though there are several from my neghbors that are visible if I use the Netgear card. I didn't do anything further with it until Monday when I was back at PSU. And this time I could not connect at all. For some reason it would no longer connect to pubnet.pdx.edu. I tried everything I knew how to do, and after half an hour just put the Netgear card in so I could get a connection.

When I got home last night I decided to install Wicd, which automatically uninstalled Network Manager and Wifi-Radar. (A lot of people on the LTP e-list say they much prefer it over network-manager.) It was afterwards that I discovered that I had no wired connection either. Thankfully, that is now fixed (what made eth0 go away?), but I still need to figure out what is wrong with the wireless.

I see the 4965agn with lspci, and it appears in the GUI, but the GUI says it is not configured, and "sudo iwlist wlan0 scan" says "No scan results." Here is some output:

jjj at Devil7:~$ sudo iwlist wlan0 scan
wlan0     No scan results

I edited the /etc/network/interfaces file so it says:

auto lo
iface lo inet loopback
iface wlan0 inet dhcp
#iface ath1 inet dhcp (the Netgear card)
wireless-essid pubnet.pdx.edu
auto wlan0
#auto ath1 (the Netgear card)

And then I did:

jjj at Devil7:~$ sudo /etc/init.d/networking restart

And I still get no scan results. I know when I finally figure out what is wrong it will turn out to be something really stupid.
