The router iteself is one of the easiest available. I have had mine for a year or so. As long as your PCs are set up on the same sub net via the router, you should not have a problem. Need to decide if you are going to use DHCP or static IP addresses for your PCs. There are many considerations, but once you decide on how you want to set up your network, it is relatively easy to configure in the Linksys. I have found Linksys telephone support to be decent. If you want to email me, my address is in my profile.

PS. I didn't receive a blue cable with mine, is it by chance a cross over cable instead of CAT5?
