|Actually, my "main" PC does not have the wireless router, but only has a wireless NIC. The PC that has the wireless router or gateway (it's an ActionTec wireless modem) is elsewhere in the home and is not mine. I'm just connecting to that existing wireless network with my "main" PC so I can get out to the internet.|
Then, my "main" PC also has another, cable-type (non-wireless) NIC, and so does my second PC, and my two PCs are both cabled to the Netgear 8-port switch - nothing else is cabled to that switch.
So, I'm hoping to be able to get my 2 PCs to see each other, and for my second PC to get internet access via my "main" PC.
So, from the standpoint of my "main" PC, I have two networks. One wireless and one local cabled network (the one that uses the Netgear switch). But that second network between my two PCs is the one that says no connectivity is present.
Do I need more than a simple ethernet switch between my 2 PCs? Do I need a "gateway" or a router of some kind to manage traffic between them? Can my "main" PC be configured to be a gateway or router without damaging the connectivity on its wireless NIC with the existing wireless network in the rest of the home?
