CM1100 No Longer Compatible with Xfinity Due to Security Software
Xfinity sent out an email that my CM1100 modem is no longer compatible with the 800 Mbps plan even though the specs on the device exceeds that. Xfinity's initial reason was due to INCOMPATIBLE BASED...
I have been running a number of different speed test. It has been bouncing around a little more and has been a little lower, especially with Xfinity's soeed test. I was at 600 Mbps plan and saw upper 500s Mbps into 700s Mbps range. Test over last day been more mid 500s Mbps but the one I just ran went over 700 Mbps again. I can't help to wonder if Xfinity sends out the notice and does something.
What Firmware version is currently loaded?
Please post a copy and paste of the modems connection status and event log page.

Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
What is the brand and model of the host wifi router connected to the modem?
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

ISPs don't seem to notify there users of any changes in service sometimes.
I'd contact the ISP to check to see which speed tier they have you on. CC/XF changed there speed tiers last year and seem to have removed the 1GB plan and split it into a 800Mb and 1.2Gb plan. This cause some issue with other NG products that don't support 1.2Gb speeds with 1Gb max supporting products.

In looking through the logs, did raise a question regarding posting. I see MAC addresses etc. that I wonder if shouldn't be posted. What is the risk level of sharing the modem connection status and event log page? Is there something I should be looking for?
I am currently using a CAT 5e cable... I was previously on 600 Mbps plan that they are bumping to 800 Mbps. With getting close to 1 GB probably makes sense to swap in a CAT 6 cable. The distance I need is only around 15 feet. Any CAT 6 cable recommendation and are there any on Amazon that are good?

What is the risk level of sharing the modem connection status and event log page? Is there something I should be looking for? The cable connection pages are fine as is. Just copy and paste into a word processing program and save as a pdf for attaching (not insert) to a message reply.
The event logs are good to copy and paste into a word processing page also. There you can do a global search and replace for the first two or three pairs of the MAC address. The one you are most concerned about is the one that follows CM-MAC. That is the MAC address of your personal cable modem. The one that starts with CMTS (Cable Modem Termination System) is the MAC address of your ISP's head end.

The distance I need is only around 15 feet. Any CAT 6 cable recommendation and are there any on Amazon that are good? Amazon Basic are very serviceable. Nothing wrong with some different colors so they are easy to keep track of.
We are looking for the CABLE EVENTS Log please. EVENTS Logs will have markings of Critical, Warnings and Notice.
Yan can edit out any CM MAC ADDRESSES.
We need to see the Cable Connections status page and EVENTS logs pages so we can help give you some information to the ISP and to NG for review. If we can't see these then we can't help you more.

- I will work on getting those logs.
Regarding Cat 6 cables... I see people post how they have to meet certain specs, such as wires being awg 23, etc.... others say it just has to support data level. I noticed lots cat 6 cables are actuall awg 24 to 26. What does it truly come down to for it to be a Cat 6 cable?
