Docsis 3.1 speed issue

I currently subscribe to Docsis 3.1 and I am not getting the advertised download speed. I can get up to 500 Mbs download ang 40 Mbs upload on a wired connection using an Arris SB8200. My download bonded channels shows 25 channels (check the last channel #159) rather than 16,24 or 32 channels I would expect. I got a tech visit that did not uncover issues with my setup or cabling. Any feedback or advise is greatly appreciated as to how can I resolve the speed issues. I am posting some screen captures of the SB8200

Also post the up and downsteam power levels, and the downstream SNR values and error counts.

They are posted. I attached 2 screen shots with the original post: Upstream/Downstream and event log. I am not sure why you do not see them.

I can see the Event Log image, but the other one looks like this:

 


 

An employee or one of the Experts may be able to see that image, but I cannot. Sorry!

Re: Docsis 3.1 speed issue

Your upstream/downstream stats are similar to minre. Are you able to get to 800 Mbts/Second on a download?

Does your router have any traffic management, QOS, or traffic meter enabled? If so, try disabling them.

Yes, the router has these settings, but they have never been turned on. It seemed to have been an issue with Comcast upstream equipment. The last tech opened up a ticket with maintenance that finally closed this week. Now I am getting 850+ downloads when wired directly to the router and 950+ when hooked to the modem directly.
