I'm having difficulty with the networking system of windows 7. I am using a laptop in the office and what I want to do is to access the printer of a desktop computer via a wifi router. I can see the desktop computer, but I cannot access the public folder nor can I access the printer. Both my laptop and the desktop computers are running windows 7 home basic. my wifi router is a linksys router model WRT120N. I've originally set up the network workplace and now I've changed it to homegroup just to try and see if I can print but apparently I still can't find the printer. I've tried playing LAN games on both the laptop and the desktop and it's ok. I've tried shutting down kaspersky internet security in any case the firewall is hindering anything but still can't find the printer. Any ideas how to fix my problem?
