Good morning. I am trying to get 2 Gateway routers to play nice on the same network. On the 1st floor, i have a coax feed going into the main(1st) router. I am using its ethernet ports as well as the 2.4 and 5GHZ radios. In my 2nd floor bedroom, I have another coax connection. This is where I want to use the second router. I'm interested only in its ethernet ports.
I followed the directions from another post on here, but I am still having issues. I disabled both wireless radios on the 2nd router, but that didn't help. The laptop that I used to configure the 2nd router kept its internet connection. However, the devices that are wirelessly connected to the main router are losing their connections. There were 2 devices, specifically, that weren't connecting at all. Everything returned to normal after I unplugged the 2nd router. What am I overlooking or doing wrong?
