speed

I was at the basic internet package. When the price went up, I was told if I upgraded to gig speed, it would be less money. I received and set up a router/modem that is meant to handle that speed. However, I am still getting in the range of 250 MBPS, consistently. I have been on chat and phone calls with support several times, they restart, reset, and provision the modem, nothing changes. I agreed to have a tech visit, but they made it for the wrong day so I cancelled it. Plus I don't trust them to not charge me for something. 

  I still have my previous router/modem, and Arris SBG10 which should handle that speed (although I was told it wouldn't). I am wondering if I will ever get more speed. Should I just try my old modem again? What would happen if I had two modems set up?

FWIW. The SBG10 will not do gig speed. It is rated by them for up to 392 Mbps.

It's probably a speed provisioning / bootfile issue that only a rep would be able to correct.

from the Arris website - "The SBG10 has wired speeds up to 686 Mbps, Wi-Fi up to 1600 Mbps, DOCSIS 3.0, dual AC1600 Wi-Fi, two 1Gb Ethernet ports, and is best for up to 400 Mbps." I would be happy with 500 MBPS.

Plus I don't understand what is so hard. If Xfinity is sending me 1000MBPS and they send me equipment that is supposed to handle 1000Mbps, why isn't it plug and play? Why all the difficulty? I was on chat for THREE hours trying to set up the darn thing.

Concerning the SBG10, it doesn't matter what a manufacturer's speed claim may be. The only thing that matters is what speeds Comcast will provision it for.

well I tried hooking up the Arris again and it wanted me to download the Xfinity app, which I already have. I couldn't get beyond that. I give up. There are "proposed route" flags for Fidium in my development, I am hoping it will be an option soon.  I've lived through 56Kbps, I guess I can deal with this.

I'm going to escalate your issue to the Comcast corporate employees (The Digital Care Team) who are available to these boards for assistance. Good luck !

Hello, @user_ws9oyo. Thank you for making us aware that you're not getting proper internet speeds even after activating our modem. I would be more than happy to review your account to see what we can do to fix this.
