It [msn messenger] works for like, a minute, and then (forgive me, my knowledge of computers is awful) my computer will give a sign to say 'limited wireless connection' and then our router freezes, and internet is cut off from all the computers in the house and once or twice my Dad's computer has frozen as well...
To start it up again we have to restart all of the computers, unplug the wireless thing and let it cool down for a minute or two and then plug it back in.
..if I log back onto msn, it happens all over again.
