My family has a 1 GB Xfinity (comcast) WiFi w/ voice plan and the included modem / router combo isn't giving us the speed we want. We only have roughly 15-20 devices connected at any time and only I use a substantial amount of bandwidth. When no one else is connected to the WiFi, I get 250 mb/s down on my phone and 350 mb/s down on my PC, roughly 30 ft from the router. On a wired connection, I get 450 - 500 mb/s down which still isn't close to the 1 GB that we pay for. I've been looking around the internet for reviews on the possible upgrades and every website has a different opinion, so I'm asking if anyone had a similar experience with Xfinity and what modem / router I can buy to improve my speeds.
P.S. I don't need to have a modem / router combo
P.P.S Money isn't an issue
Thanks All!
