Running an ethernet cable to TV from airport as opposed to cable modem
Hi,
I recently purchased a 4k smart TV, and a friend recommended that I hook it up via a Cat 6 ethernet cable instead of relying on wi-fi due to the amount of data that 4k requires. I was wondering if there would be any difference if I ran the cable from my Airport, instead of my cable modem. Essentially, would running an ethernet cable from the airport slow the speed of devices connecting to the airport wirelessly, or would this not affect the speed at all? I would rather not connect it directly to the cable modem as it would then technically be on a separate network than all of my other devices, but if I would get better performance that way, then I will do that.
Thanks!
