How can I use a 2nd router as a wireless access point for the same single network (Xfinity)
Title ^
Context:
The main Xfinity modem is on the first floor of the house, and the wifi signal can't reach the desired room on the second floor. There is, however, a coax cable (I assume the same one that allows the original modem to work?) running up through the floor to the second floor room, so I thought I could use this with another router. Plugged in a second router (Motorola MG7700) upstairs and I've been able to connect to it via my phone and change the default username/password and other settings. Not sure if it was correct, but I read that I would have to disable DHCP service to get this thing to work for what I'm trying to do. Did that, and now I can't connect to it anymore so I'll probably factory reset it at some point.
But yeah, can this actually be done, or is it not allowed with Comcast, etc.? Appreciate any insight y'all can give me. :)
PS: Running an Ethernet cable up the stairs, or through the walls with the other coax cable, isn't an option, unfortunately.
