Hello, I just replaced a dumb hub with a Linksys wireless router. I added the linksys because the office wanted DSL. I have 3 desktop computers and a wireless laptop. The main computer is XP and has a laser printer attached. I did my confguration where I was able to have the other three computers ( 2 XPs and a 98 ), access files and the laser printer off of the main computer. The main computer, however, can not see the workgroup so can not see the other computers. I have changed the workgroup to a unique name on all computers. I think that part is correct otherwise the computers could not access the files and printer of the main computer.
