In the last month or two my internet has been going out multiple time through out the day and some of the cable channels get garbled from time to time. When we first moved in to this house 2 yrs ago we had a service tech come out and he installed a Commscope Amplifier and everything was right as rain.
With the random number of disconnects through the day it's making online gaming and streaming unenjoyable.
The line coming in from the pole is split once to the amp. There are no other splitters. All wires coming out of the amp go directly to wall plates except the modem it connected directly to the wire comeing from the amp.
I have a Arris SB6183 modem which is about 4yrs old or so. I'll post what my Status Page and Event Log looks like.

The signal levels and SNR values you posted look good, but the error log entries suggest there is a problem.
If you want to troubleshoot this yourself, please see Connection Troubleshooting Tips. Loss of Internet and TV service is often due to a poor connection between your equipment and Comcast's network, usually in or near your home.
If you can't find the problem or you'd rather have Comcast do the troubleshooting, call them at the phone number on your bill or 1-800-Comcast, or chat with them using the Internet Support option at https://support.xfinity.com/chat. If they can't fix the problem remotely, insist they send a tech out to identify the cause and correct it.
If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit unless you have their Service Protection Plan (https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast rental device, or anything outside your home, you shouldn't be charged.
Hi there, Dumpster-Tom.
I would love to help out and resolve any issues that you might be having with the Internet service. I want to dive deeper into your account.
Can you please private message me your full name? Thank you for posting to our forums.

I had exactly the same.
First, disconnect your home network, and just plug straight into the modem. Reset the modem so your PC gets the IP address. If you see NO errors, then is it something on your internal network (cabling/bad splitter/etc). If you continue to see errors then have a technician come out. In my case, it was the tap, where my cable joins to the "backbone" - my neighbour had a bad line causing significant noise, which was interuppting my line. The first call out tech did the basics of replacing my connectors. I called back (as the errors continued as you described) and the "Advanced Tech" found the above.
Hope that helps.

FWIW, anything on the LAN side of the modem cannot be the cause of those WAN side RF based / system connection quality errors.
Had a tech come out really nice guy. He checked the drop coming from the pole and all the numbers we're in spec or better. He ran a few other test and everything was good. So just to be safe he replaced the drop and all the hardware outside.
Since he's left the modem hasn't had a T3/T4 Timeout and all my correctable/Uncorrectables are zero. So fingers crossed....
He did give me his number in case I do suffer another T3/T4 Timeout.
Dumpster-Tom, how has everything been working since the tech came by? I want to make sure everything is working consistently.
Glad to hear it! I'll go ahead and lock this thread. If you run into any other issues, please reach out again.
