wireless configuration

[steve%prd.co.uk@localhost (Steve Blinkhorn)]

I have a machine running amd64 7.0 that has an Intel Centrino type
wireless device.   This is recognised and configured at boot time at
iwn0 as one would expect, but shows up in ifconfig -a with "No
network".   The router with the specified SSID is running properly,
and other wireless devices access it normally.   But the router is too
modern to support WEP encryption.   Is encryption likely to be the
problem?   Other suggestions?
