Wireless N. Firstly, to start with, my computer is running of Wireless atm as I've just moved house and theres no ethernet port anywhere near it. Got a wireless N USB adaptor thing and it works fine. The only problem is that when I start running too many processes that require using the connection it just cuts off, and then the computer just freezes until the connection comes back.
I sorta have the impression that having the wireless adaptor sitting behind a 415V 3 Phase connection running through the walls might have something to go with it, but I've gotten a USB extension lead and moved the adaptor away from the power connection, but it makes no difference. I can't really play any games over the net with this happening, and I dont get my CAT 5E port installed in the room until 1 there is a place for the computer to go and 2 when I get dad to go under the house and install it. Probably 3-4 months I'd imagine.
