Hi I have networked computers before using Ethernet cable. I have my computers working wireless using power lines (UK) mains plugs that has an Ethernet cables to conect to the PCs. Can these be networked as both PCs can access the wireless router?
You can use both if you want, just define the wired adapters with IPs on the same subnet with no default gateway. Then you can use wired between those PC's and wireless for the internet.
