So a couple of days ago i moved to a new house. This house has ethernet wiring in it. So the previous owners had AT&T but i have Spectrum so the guy came out hooked it up whatever. I hooked up the router.Later that night i get my pc here and i plug it into the ethernet in the wall and i got nothing. So i thought is the cable bad inside to i got my smart tv and plugged it in to another ethernet port in the house and nothing. Keeping in mind the router is just fine no probs with that. So i thought well maybe the switch is bad for the house. I went to Best Buy and got a new switch. Got home configured it and everything got it set up and still NOTHING. So at this point im so confused becuase my router is working fine but whenever i plug in a second device it never works so i there a limitation on modems on how many devices you can have.
