I even found out that Comcast was doing work in my area that day to improve the speeds

Great router- works really well through my entire home.

Only issue was the phone line was not working.

Took very little time to have it up and running, and it's working great.

, my rental from Xfinity would only connect 72mpbs on 2.4ghz, and 320 mpbs on 5ghz, voice works great to on landline, no noise or distortion.

The Modem it's self works very well, But not for 1 Gigabit internet service

As I mentioned, connecting this device to another wifi router works well for me

Works fine and does work with Comcast and has phone jack

Yay, everything's working!

The replacement router is working very well

Let me first say that so far its working as good if not better than the XB3 Comcast provided modem/router/tel

work's good

Unit is working well with solid performance and good bandwidth.

Once installation was FINALLY successful after many attempts, the modem itself seems to be fast & works well

"Arris SB6190" which is working great, but since I have added voice, I need to upgrade the modem

We are very satisfied with this product is working very well for us in all the devices good quality

I replaced my internet provider's modem with this and it has worked well; and saving the monthly $10 rental fee will pay this off over time.
