I have wireless!
IMO, it's been great for me because my PC is in the kitchen yet the computer points are all the way down the long hallway in the sitting room so I either had to have cables running up the walls or buy wireless.
My modem is from UKOnline and I have a 2 meg net connection with them as well. I had to buy the wireless stuff seperate - it's a Netgear wireless USB adaptor - it's been great!
I normally have 56Mbps speed which is the max it can go, but sometimes it might drop to 24Mbps if the sitting room door is shut (there's a brick wall near as well so the signal has to zap through that!).
Here is what I have:
It was really easy to set up with my modem and before when I used to have a laptop, I can't believe that I didn't go wireless sooner!
