Why do I lose my wireless printer connection?

I have a Dell desktop (running XP Home) in my kitchen that uses a wireless connection to connect to my hub to access my printer and cable modem. Typically after a power fluctuation (or outage) we have to reinstall the printer drivers to be able to use the printer (Konica-Minolta Laser). The internet connection doesn't die. The computers hard wired to the hub don't ever have this problem. I upgraded the hub to a "Linksys Wireless - G" thinking it was a hub issue, but, needless to say, this didn't fix it. Any idea what is going on?
