I've not been able to connect to my wireless broadband for about 3 days (I'm using an ethernet cable instead) and it's a bit annoying. I think part of the problem is that I reset the hub due to some problems and the Mac is mis-remembering the password settings (something to do with WEP and WPA) and, cos it no longer asks me for a password and goes straight for what it thinks the password is, it never works.

This may not make sense but basically I'm convinced that if I can get the Mac to forget the password and ask me to enter one I can get the Wireless thing to start working again.

I tried phoning BT's tech support line but the guy knew fuck-all about Macs.
