7.10 can't connect to Apple airport WPA2
I'm running Ubuntu 7.10 on my laptop and everything works fine at home, but when I try to connect to the network at work nothing seems to happen. I believe the connection at work uses WPA2 so I'm wondering if maybe it's not supported by the driver I'm using? I don't really know how to troubleshoot wireless issues, but I can't really use Linux on my laptop at work (and show it off to my co-workers!) if I can't get online.
If I try to ping my router I get 'Destination Host Unreachable'.
I've tried googling the issue but most of what I find is several years out of date, and since everything works when I'm at home I want to be a bit careful about making changes.
So the question is, if I can't get on to a particular connection, but wireless works in general, how do I troubleshoot?
thanks in advance!
