I have 3 computers connected via ethernet cable all running to a router in my garage which is hooked up to a cable modem. I also have a laptop which has a built in wireless connection and connects to the wireless signal created by an access point. The access point is given its signal from an ethernet cable which also runs into the garage. All of the computers I am trying to network run Windows XP. I am trying to set up a home network with file sharing, the computers have different names, they are all in the same workgroup, but whenever I go to see the other workgroup computers, I either can't see the other computers, or I get an error that says I don't have access to that resource and that the path cannot be found. I'm pretty sure I get this problem because I can't ping any of the other computers from any computer. Please tell me how to fix this problem. Thanks in advance.
