2 gbps plan but only getting 1.3 gbps

I’m on the 2 Gbps plan using my own Motorola MB8611 modem. On the modem’s status page I only see 34 downstream bonded channels (DOCSIS 3.0), and no OFDM downstream channel listed. My speedtests top out at about 1.3 Gbps.

Since DOCSIS 3.0 tops out around 1.3 Gbps, it looks like my modem hasn’t been provisioned for DOCSIS 3.1 / OFDM. Can you check if:

My account has the correct DOCSIS 3.1 config file pushed to the modem.
My local node actually supports OFDM downstream channels for the 2 Gbps plan.
If not, what upgrade timeline exists for my area?”

The cable from the modem to the router is 6e, the router is a TP-Link Deco BE63, and the cable from the router to the ethernet in my desktop is also 6e. The ethernet is Killer E3100G 2.5 Gigabit.

Thanks for posting on our Community Forums, user_xnjbui. Unfortunately, we’re unable to configure DOCSIS 3.1 remotely. The only way to upgrade would be to replace your current device with one that supports DOCSIS 3.1. For more information on which devices are compatible with our services, you can visit us HERE.

As you would know if you had bothered to check, the MB8611 IS a DOCSIS 3.1 device!

... MB8611 modem ... I only see 34 downstream bonded channels ... and no OFDM downstream channel ...

Could you post the downstream channel stats? I've never heard of a modem showing more than 32 downstream channels unless two of them were OFDM.

I have the same problem, 2Gig plan and only 1300 Mbps download speed.

Xfinity info about my Internet service:

Change Plan/Current Internet Plan it shows 1.2Gig Down / 1.2Gig Up

Your equipment: Motorola MB8611: Cable Modem

Your Plan: Download Speed: Up to 2000 Mbps, Upload Speed: 250 Mbps

Also: the MB8611 only has 25/32 Downstream Bonded Channels Locked (24 each QAM256 + 1 each OFDM PLC-corrected=14,535,871)

Upstream: 4/8 Channels Connected (SC-QAM)

All of my equipment (router & Switch) is 2.5Gig.

I have the computer directly connected on the router 2.5Gig port.

What Next?
