A simple problem that you might have is that your wireless interface (eth1 or whatever) might not be marked as auto. auto ath0 is not put in the configuration file by the Ubuntu install, but I tried putting it there without result. I'm slightly familiar with the interfaces file. I've done a kludge which works, although it's pretty ugly. I've configured both eth0 and ath0 in the interfaces file, and put a three line script in /etc/init.d/rcS.d which removes the route to eth0 after the network comes up. #!/bin/bash route del default eth0 echo Horrible Kludge That actually works! I can't say I really know why. If I don't remove the route, there are two default routes which causes networking to get confused. Needless to say, I'm not using ethernet :-) The only good thing is that the people using the machine will never know how ugly that is. Also of consideration is that depending on how your wireless interface is physically integrated (my HP/Compaq laptop uses a special USB interface) might also determine when it is available to be upped (it might be hotpluggable). Do you have a Function-F2 or somesuch that turns wireless on or off - this might also cause the non-appearance of the device? The pcmcia card is hotpluggable (which I only know because it comes to life during the hotplug boot process). I don't know anything about a special function key (how would I find out? is this hardware specific?), but the wireless always connects but only after eth0 is activated. You probably need to check out the tail of /var/log/kern.log and /var/log/messages for pertinent warnings/errors. I've left it at the office, so next time I've got the machine in my hands I'll check the logs. For some reason I didn't think to do that. Lots of other people seem to be using the atheros cards without any problems, so I guess it's something specific that I'm doing. This problem exists after a bog standard, unammended Ubuntu Hoary install. Many thanks... David. I can't get my wireless to connect at boot. This is causing me embarrassment because I keep telling everyone they should use Linux :( From a fresh install of Ubuntu Hoary, specifying wireless for my net connection, wireless fails to connect. Signal is NOT a problem. HOWEVER: If I deactivate wireless, manually create an ethernet connection with the network panel, activate ethernet, deactivate ethernet, then activate wireless.. i get my wireless back! I've been able to replicate this consistantly. Simply restarting networking doesn't work. I have to go through that ritual. Without doing that, all the settings in the network panel look OK but the MAC address shown by iwconfig is FF:FF:FF:FF:FF:FF and the flashing lights indicate no connection. ifconfig gives the right ip address etc and route shows the right gateway (192.168.0.1) on ath0 Dell Inspiron 4000, Netgear WGT624v2 AP, Netgear WG511T pcmcia card, atheros chipset, using WEP 64bit key and static IP. This is getting to be a showstopper for using Ubuntu. Works fine for WinME dual booted on the same machine :( If anyone is getting good results using a similar set up, I'd love to know what I'm doing wrong. regards... David.

It just does this wierd behaviour where it will only work once the ethernet has been brought up.
