Seems the modem/router I had been happily using for months decided to give up the ghost while I was trying to get a wireless network running in my house.
This annoys me hugely, because yesterday I spent about 12 hours trying to get wifi working, only to discover tonight that the hardware was broken, so it wasn’t a problem I should have spent all that time on :-/
So, tomorrow I need to go buy a new hub/switch, so that I can have multiple computers on my LAN.
