Xfinity router xb8-t

I just want to say Xfinity router looks super nice xb8t-t but has the worst performerce, the internet drops like 6 times a day the modem/router is getting super hot,I called customer service but they don't know any better, had a technician over didn't know how to fix it THE BEST WAY STAY WITH YOUR OWN MODEM if you want to have internet 

The worst part they don't  log when you tell them what is the  problems with  the modemn all they do, they are  try to sell you something else like more expensive internet or phone etc, also the technician is  a contractor and his trying to do more usless work just for him to get more paid from Comcast 

You are better off to buy your own  router
