Arris SB 8200 Mediacom 1Gb plan

  I just recently purchased the SB8200 because the modem that i was renting through the provider would never let me get more than 350mbps download and 55 upload and that's on a good day, when im paying for 1GB service.

   I live in a town that is fairly small and almost an hour from any bigger cities. When I started my plan through them they put new cable all the way out to the power line. So I know there's no problems with the line at least that has been found.

    I am also renting EERO devices for an additional 16$ a month just so i can manage who is on my network and set time limits for the kiddos otherwise I would not be able to receive/modify any of my network settings right?. I feel as if my provider is lying to me that 1GB service is supported in my area. 

 Every tech that has came out makes up a new excuse each time and they always say that the speed looks good on there end but it could be my devices or some other excuse. The only reason that I'm renting the Eero devices is because the mediacom Android app does not let you see any connected devices/data usage or anything to do with my account yet they still want to charge rental fee just for us to be able to manage it.

And the next closest speed package they have is like 200 Mbps download so that is a big difference in my opinion when I first started with him I was getting 600 Mbps but I no longer provide that they said. Any help would be greatly appreciated.
