I hope someone can help me here. I have a cable modem which is connected to my router. I then have a ethernet cable which connects my router to a switch in my house that connects various hardwired ethernet outlets throughout the house.
Everything was working fine for months since I set the system up. Now if I have the switch connected to the router, I have no access to the internet (either hardwired or wifi). I can't even connect to the router through wifi via the router's ip address. As soon as I disconnect the switch, the wifi works fine, but of course, none of my hardwired outlets work.
I have done powercycling the modem and router, reset the router to factory settings, have the latest firmware, etc. Nothing changes the situation.
Any ideas? Thanks!
