I currently use a D-Link DI-624 wireless router, 802.11 G built-in wireless PC card for laptop and a D-Link DP-G310 wireless print server.
Desktop is connected to the router as well as the print server. Laptop is connected wirelessly and with the DP-G310, I am able to print wirelessly as well with my laptop.
Range is very good. Even on "low" signal strength, speed decrease is hardly noticeable.
Security is nothing to worry about anymore, in my opinion. I live in a nice neighborhood (know my neighbors and I know their lack of computer knowledge), have WEP enabled, plus I use a software firewall on both computers (Sygate Personal Firewall PRO). Never have had a problem with wireless in over 2.5 years that I have used it.
