Today i got AT&T U-Verse internet and i got the standard in home install... with the typical modem/router combo "gateway." I want to soon use my own modem and router. Would it be possible to do that, use my own modem and router? They would be a Zoom 5341J modem and a TP-LINK TL-WDR3500 router. I notice that there is no coax cable right now, instead, the tech plugged an RJ-11 cable into the gateway instead of what i imagine would be a coax for WAN input, so would i use an RJ-11 to Coax adapter or get a tech to come out and run a coax line for me? Even then, if i had all the cables and the modem and router, would it work... or am i forced to use AT&T's cheap gear?
