ARRIS . TG3482G and netgear router AC900/R7000 how do I bring wifi internet to router or how do I reprogram rouer to use wifi.
Re: Xfinty wifi
The TG3482G is a combo device. The means its a modem/router device. Are you planning on using it as a router as well as the R7000? If so, you'll need to place the R7000 in ap mode. otherwise you'll have a double nat situation. The manual walks you through placing the R7000 in ap mode.
I'd usually recommend making sure the R7000 has the latest firmware but that last several versions have had issues. The most stable right now is the .42 firmware.
