I set up a wireless network at home this week, primarily so I could get internet access in the garage without having to run wires.
I'm using a Linksys DSL router (yes, with the latest f/w) and USB adapter, configured with 64-bit WEP and only the MACs on my network allowed in.
So I'm playing with the monitoring s/w, and it looks like the SSID of my access point has changed. Hmm. Turns out it didn't - my own DSL connect dropped, and I was picking up some neighbor's connection! At one point, I had 4 different connections to choose from, all with the defailt SSID and no encryption! Let that be a lesson to those of you considering going wireless.
Here's my setup - I hardly need to go back in the house!
