I have a single ethernet outlet on my modem. how can I turn it into 2 for computer and tv?
I have no knowledge about gateways and routers.
I use this for all my ethernet connections to my XB6:
Use a switch or a wireless router, both have multiple ports to use
@glitches3 You can't use an ethernet switch hung off of a straight cable modem (sounds like that's what you have) without having an additional Public / WAN IP address assigned from Comcast (if it's even available anymore). What is the exact make and model number of the modem ?
If it has 4 ports then it sounds like it is a combo modem / router gateway device, not just a "modem" (the term you used). The terms are not interchangeable FWIW, but everybody does it anyway.
