I suppose I could incorporate the commands ifdown eth1, ifup eth1, and dhclient eth1 into the startup sequence, but I feel like that would be more like stepping around the problem as opposed to fixing it.
Are you rebooting from scratch or resuming from hibernate? I have the same card and sometimes if I hibernate my laptop while using a certain network (say byuc0ug4rs) and then wake it up on my home network, I have to drop byuc0ug4rs and pick up my essid with iwconfig or cardctl. One way I fixed this was to add "ifdown eth1" to the hibernate script, and remove network configuration from the boot process. Then, every time I fired up my computer, I had a fresh start with whatever network I wanted.
Also, occasionally, the wireless will just stop working in the middle of doing things after it has been working just fine, and it won't work again until I reboot, deactivate and activate again.
Where does this occur? At your house? If so, a number of things can be a factor. The ones I've experienced with the same card are competing signals from other networks in range, the microwave, and our cordless phone. If you have a cordless phone, you'll notice that the frequencies of your phone and your wireless network are amazingly similar. Next time it "just stops" look around and see where you are and what other appliances are near you, or if you are in a collision zone between your essid and another one.
Some other things to note is that when the computer is booting up, it often pauses on "Configuring Network Interfaces..." for quite a long time before it moves on, and the "synchronizing clock with ntp.ubuntulinux.org" part often (but not always) fails.
See above. You can remove "Configuring Network Interfaces" from running at boot, or you can see below and use an automatic detector/configurator like the one Phillip showed me.
On a seperate note, I would like to be able to connect to various wireless networks (such as BYU, home, friend's house) without going in and changing the settings manually for each network I visit. I downloaded and installed network-manager, but I'm really not sure how it works...
If you go to the uug website and look through the mailing list archives, you'll find a post where Phillip Hellewell helped me out with a script he created to automatically detect and configure the appropriate wireless network using wireless.opts and cardctl. Good luck and let us know how it turns out. -- Alex Esplin -------------------- BYU Unix Users Group http://uug.byu.edu/ The opinions expressed in this message are the responsibility of their author.
