Starting to get even more interesting...

Again no luck connecting to the office 3com router (OfficeConnect
Wireless 11G BTW) either with WEP or without any encryption; WPA
worked first time [;^). The only trouble I am having now is that the
interface goes down ever so often -
....

I seem to be keeping the link up most of the time with constant ping
to the router (which is  about 8m away from the laptop in clear line
of sight).

I wonder if there is some timeout value to be tweaked; I will start
the supplicant in debug mode next time to see if this will make any
change.
