[ubuntu-uk] Wireless woes

[Sean Miller]

Just replaced wireless router and, for some reason, my Ubuntu won't
see the network.

It sees the neighbours' and it sees another that is somewhere or other
in the vicinity but not mine.

Windows XP on the same machine is fine, and this laptop I'm using to
write this (Vista, bah!) sees it fine with high signal strength.

Anybody any ideas why it would just be my network that is being ignored?

It's currently unsecured, btw.  Could that be a factor?
