I plan on buying a Netcomm NF4V and then using a powerline adapter to get a wired connection upstairs so I can have a wired connection to my PS4 or my Xbox 360. I was wondering though if I could plug the ethernet cable into my current router (Linksys WAG 120N) so that I can have a wired connection to both my PS4 and my Xbox 360 at the same time. My problem is though I don't know if you can link 2 routers together and use both at the same time. My second problem is my WAG 120N only has a DSL plug so is it possible to link it to the new router? How would I do it?
Basically I want it to go like this: NF4V plugs into the jackpoint > Ethernet cables comes out an ethernet port and into a powerline adapter > A cable comes out the other powerline adapter and into my WAG 120N > I then use the ethernet ports in the WAG 120N to give me a wired connection to my PS4 and Xbox 360. All of this happens while I can still use the wifi on the NF4V.
Can I do this? How do I connect the WAG 120N when It only has a DSL port?
