1200 service always low

If you have a proper setup and everything is working right you should see 1200+ on a 1200 plan, likely 1400-1440 as Comcast tends to overprovision a bit, often ~20%.  You need 2.5Gb or faster wired ethernet to hit those speeds reliably.  1Gb ethernet will get you 900-something, typically 950 or so.  It's theoretically possible to hit those speeds on WiFi with the right equipment under proper conditions, but it's better to test with a wired connection first.  Wired connections are more reliable and are far less susceptible to interference.

That said you should not be getting 80 on a wired connection.  Probably not on WiFi either, but again let's not test on WiFi if possible.

This smells like a Comcast line problem, so could you check and post the signal stats and error log from your modem?  It varies by modem, but there's a little info on it here:  ‎Internet Troubleshooting Tips | Xfinity Community Forum  Be sure to redact any IP addressess and MAC addresses (CM-MAC, etc.), especially from the error log.  The forum regards them as private personal information and will block your post if you include them.  Also it works best to copy and paste rather than posting screen shots.  The forum does quite well with pasted tables and they are usually far more readable than a screen shot.

So... modem won't cough up signal stats?  There should be some tables full of numbers in there.  Those tables not being present is more than a little ugly.  What modem do you have?  Still smells like a line problem, and thus something Comcast will have to fix.

That's interesting. I put these stats in a reply to you and it got deleted it seems

Saturday when I checked it showed status "Good"  now it shows poor. My speed test right now is showing 158 D 39 U with 14ms ping. 

I am using a slightly older (2018) ASUS ROG MB with a built in Intel ethernet adapter probably only 1Gb I am using the Netgear CM2000 with an Archer AX6000. I bought these right after upgrading my service. 

Here are the last two entries from the log followed by the upstream and downstream power and noise. 

Some of my posts are marked as private I am not sure why 

reposting this just in case

Lets try this again, they keep getting flagged private 

This may or may not be the root cause of the problem (YMMV) but it needs to be addressed regardless. 

The upstream power is too high and it may be intermittently fluctuating even higher to out-of-spec levels. The downstream power is on the low / weak side as well. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.

In an effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1000 MHz, bi-directional, and no gold colored garbage from Radio Shack, Home Depot, Target, etc. Splitters should be swapped with known to be good / new ones to test.

Also check the coax cable for any damage such as cuts, nicks, abrasions, kinks, sharp bends, etc.

If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two-way splitter connected directly off of the drop from the street / pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.

Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home. And if the problem is found to be on their side of the demarcation point, there will not be any charge.

Good luck !

Yep !

Also will a junction box buried in a foot of snow cause any issues. 

Possibly if water is infiltrating the hardware / equipment / cables.

Waiting for the connectors from Amazon but decided to Cheech the modem again.  Speeds are still only 50 Mbps but upload remains around 35 Mbps even after restarting the modem. 

Cable Diagnostic

Status: Good

Action:
Your setup looks fine. If you can't access the internet, make sure you properly activated the modem. If modem has been activated and you still can't access the internet, contact your service provider for troubleshooting help.
If you can access the internet but has other internet issue, the Netgear Cable Knowledge Base can provide additional troubleshooting info.

I can't believe that the modem is reporting that the signal stats are good when they are not..... The measuring / reporting mechanism is likely to not be very accurate or granular. It can't predict what will happen 1 minute in to the future. I'm going to post my earlier comment again. "This may or may not be the root cause of the problem (YMMV) but it needs to be addressed regardless".

There may be other things going on too.
