Hey chums,

Last month we busted our 5Gb cap for only the second time ever. I wondered whether it was because my wife Skyped her sister for somewhere between half and hour and an hour. We hadn't really Skyped before, so I don't know how data-intensive it is.

Anyhow, today I got an IP conflict on my Vista laptop. From the research I've been doing, it says that this can indicate that someone's using my wifi illegally. Could this be the case? We use a password, I'm pretty sure we're using a WPA-PSK key, but I'm not going to go into the other room and grab the router password to check at this stage since the baby's asleep in there!

Today is the first time this has happened. Restarting the router didn't seem to fix it, but turning the wireless on my laptop off and then on again has enabled me to get onto the internet.

Anyhow, is there a way to find out if someone's "wardriving" us? Any other suggestions? Since I have internet access again now, should I just wait and see if it happens again?
