cclmd1984 0.0If all you have is one Xfinity device then you have an Xfinity Gateway which is a combo router/access point. If it's working fine I wouldn't upgrade it. If you need to upgrade then I'd just get a newer XFi gateway which is all in one. Buying a modem + router is gonna cost $250+, then they won't really help you if you have issues.
No_Article_2436 0.0I have Xfinity. I put their Xfi Modem/Router in Passthru mode. I use a Ubiquiti Dream Machine Pro for my router. All my devices use PiHole for DNS. So, it isn’t a problem. I was using my own Modem for years. But, after I upgraded to 2 GB service, they would not support the speed on my Modem, even though it was capable. So, I had to use their modem/router. I only agreed to update my service if I could use it in Passthru mode.
