On my home network I have a Cisco Linksys Simultaneous Dual-N Band Wireless Router that has a built-in firewall, and I run McAfee Security Center that also includes a firewall for each machine it is installed on. I tried sharing files and folders, and printers, between a wired PC and a wireless PC, but was denied. It makes no difference on a network if the PCs are wired or wireless, because they all look the same on the network, and use the same protocols.

Since I could see the other PC on the network, but I could not see any printers, or shared files and folders, I suspected the McAfee firewall was blocking the ports needed to share.

Let’s setup sharing between these computers.

First click the Windows Start button -> Control Panel -> Network and Sharing Center -> Manage Network Connections, then right-click on the Local Area Connection or Wireless Area Connection -> Properties, and make sure the File and Printer Sharing for Microsoft Networks box is checked.
