I use the Windows 7. I am using a laptop in the office and I want to do is through a WiFi router, desktop printer. I can see the desktop, but I can not access the public folder can also access the printer. Both my laptop and desktop computers running Windows 7 ultimate. My wireless router is a Linksys router model WRT120N. I had already established a network of work, and now I have to change it homegroup just try and see if I can print, but obviously I still can not find the printer. Any ideas how to solve my problems? Thanks in advance.
