Can't access wireless network Linksys BEFW1154

[Alan Milnes]

Hi

My new Ubuntu 8.04 installation can't connect to my wireless network. It 
connects fine to other wireless networks e.g. Airport Lounge, Hotels 
etc. My router is a Linksys BEFW1154 - it normally has WEP enabled but I 
tried disabling that and it still doesn't connect. I've tried googling 
but can't see anything specific.

Anyone got any ideas what I could look at?

Thanks

Alan
