I currently have an Arris Modem rented from Xfinity that I use to connect to the internet. I have an older Arris Xfinity modem that I bought at Best Buy several years ago. Is there any way to setup a network and use the older modem to boost my rented modems signal?
O/k what is the make and model number of the older Arris Xfinity "modem" ? It's probably a combo modem / router gateway device.
That can't be used as a WiFi extender / repeater.
