Yes, I'm aware of the switch on the font - this is what seems to have
stopped working - for some reason, I've always found wireless somewhat
unreliable at home (something has to be interfering with it - have a
pig of a time with mobile phone signal reliably as well), so I tend to
leave this switched off, and simply use a UTP connection.

However, when I tested things after the UNR install, I found that the
wireless wouldn't even switch on ...
