OK. i have a bt home hub and wish to network two computers. I want them to share files and a printer (that is connect to USB A on the back of the hub which works perfectly as the hub can be used as a print server). My main pc is vista which is connected via ethernet and the other is XP connected via wireless.Please give me a step-by-step guide on how to network the two! thanks! (BTW My printer is espon d78)
