The driver failed to connect, thus the password is assumed to be wrong.

It's mostly an artifact of WEP that we should fix up for WPA. > Is that just something to live with? You can disable wireless when you don't need it via the right-click menu of the applet if you like. Or, you could make the connection to your wifi AP not autoconnect (in the connection editor) and then it won't keep trying, but you'll have to manually pick the connection each time you want to connect. Might be a fair trade-off. > Also, I see there's system settings now.

You should be able to just move your user connection to a system connection by checking the "Available to all users" box in the connection editor. If you don't see it, wait for your distro to update NetworkManager to a newer version. > BTW -- one thing I've always wondered: I have an Apple laptop and the > wireless connects within seconds of waking the laptop up from sleep. > But, on my Ubuntu laptop it takes many times longer.

A few reasons: 1) Mac OS X's Airport status icon fills in the moment the card has a connection to the AP, but you don't necessarily have an IP address yet. Thus, even though Mac OS X says you're "connected", you can't actually do anything on the Internet until you get a DHCP lease. I've occasionally had Mac OS X say I'm "connected" but when I try to go somewhere immediately thereafter in safari, I can't, because the machine hasn't gotten a DHCP lease yet. 2) Apple only has a few different types of hardware, and they can concentrate all their effort on 5 or so different chips. Thus the drivers work pretty well. Linux supports ~50 or more different chips, thus the effort is divided and some drivers just don't work as well.
