answer:Could be that the printer isn't renewing its DHCP IP address? I've had notorious problems with my printer (that's wired) after it restarts. How are you sharing the printer? I'm not familiar with that printer... does handle sharing itself? Is the printer physically connected to the hub? So it's possibly one of these things: 1. Your printer can't find the hub. To check, log into your hub and look through your dhcp client list for your printer. 2. Your computer can't find your printer (over the network). If you know your printer's IP address, you can trying pinging it (to see if you can connect with it)... google "ping windows xp" for instructions. 3. Your drivers are poop and freak out/don't reset. Does this help?
