Seeing how I do have the wireless router, I really should make a point of setting this up in my house in the near future. I have heard a lot of negative stuff about wirless networks, but for some things (like say checking LJ, doing random email) they work quite well. They might not stand up to huge amounts of network traffic, but a simple solution to that is to have wireless and non-wireless networking throughout the house.
I need to ponder how to do this a bit more, but I'm quite pleased at how their setup works.
