My wi-fi is giving me grief. My Virgin Media modem is connected to a Belkin G router. I have a 1.2GHz Netbook (built in wi-fi) and I get an excellent wi-fi connection every time. Same with my iPod Touch. But my 1.8GHz desktop (USB adaptor), almost no connectivity pretty much every time.
If I keep renewing my IP, I might eventually get decent connectivity but it can take a dozen attempts or more. I make sure that only one device is using the wi-fi at any one time.
I've changed the channel (although there's only one nearby network) and moved the adaptor to a port on the front of the unit.
Desktop is about five years old running Win XP, the router is in the living room, while the desktop is in the bedroom about twenty feet away in a straight line. There's one wall between them.
The adaptor is one of these:

Someone else mentioned using a static IP. Is that easy to do?
