Wireless is crap. We kept having to reset it because it would just dissapear when you were on the internet. This new one we got isnt so bad. Desnt need resetting much, but its still slow overall.
We spoke to a guy from Virgin who said the best thing to do is to have internet ports in rooms and have a long cable to move it around the room. You should be able to get high connection speed and you dont have to spend the stupid amounts of time setting up a router and keeping on sorting it out.
