I've been using a wireless network for about two months now. I have a desktop and two laptops. All work very well. I am using Linksys and D-Link equipment purchased from Dabs and eBuyer. I have had no problems with any of it. Good luck.
There would be no speed difference between wired and wireless networks in the internet surfing speeds. Broadband runs at 512kbps (or 1Mbps or 2Mbps). Wireless networks run at 11Mbps (or 54Mbps on the 802.11a and 802.11g).
However, for transfering files between the computers, a wired network is faster (100Mbps). It is only if you are using the network to transer large files will you notice a difference in speed.
