Ok, a bit of a development - brought the lappy into work at the
weekend, so that I could play with it here - eventually managed to
connect to the WiFi, but the LED on the front appears to be very
erratic as to when it actually works.

The wireless connection was rock-solid stable - no drop outs or
anything - even managed to upgrade to 9.10 over it with no problems
whatsoever.

Back at home, I tried connecting again - ok, no problem (aside from
the aforementioned LED) but, after a while, the wireless connection
dropped out, and wouldn't reconnect - had to resort to a UTP cable
again.

The bizarre thing as that I don't happear to have any problems using
the WiFi at work, only at home, yet other people don't have any
problems using the home one ...

This is doing my noodle in ...
