T4 errors / constant disconnects

Hello,

Do you have any splitters or signal amps on the cable line going to the modem?

Thanks,

no.  this was a fresh install done in May 2016, only one line into the house, only connected to internet.  no tv services, no other services.  only one coax outlet.  when I upgraded to 300mb, a tech even redid some of the wiring outside to clean it up.

and now for over 6 months i have constant disconnects.  

for today, as of 4:16pm, and now 8:06pm, I have had 12 disconnects.

You are NOT alone. I have experienced the same problems for over two years. I connected my old cable modem to see if that was it. Had problems with that and they told me the cable modem failed and they provisioned my new one incorrectly. I threw the old one away and reconnected it with the newer DOCSIS 3.0 one. The problems continued on and off the entire time I have been at my residence.

We also have regular outages, which we are having another one for a 2nd day in a row right now. Terrible service in my area! I can't believe it, but I am actually considering DSL. I would rather have a lower speed stable connection than this high-speed intermittent connection. I mean, how much do you want to bet the same piece of local equipment is failing over and over again? You would think after the same area having outages so often, a senior tech would investigate why it is happening so often to try to come up with a long-term solution. It almost feels like they don't track that at all! 

BTW: My logs are due to the outage. Otherwise, I normally get the T4 and IPV4 timeout issues as the original poster. The installer placed my splitter in a keyed box. I guess I'll have to look at that the next time I have issues. 

Here are my logs:

flitzanu,

Would you try to a reset of your modem & bypass the router to see if you are still seeing the issue at the modem? We want to see if the issue is at the modem.

Let me guess, underground wiring that goes through a green box on your lawn? If so, have that box and line from the box to your house checked. 9/10 that is where the problem is occurring. See any Cox trucks in the area?

also, here is my disconnect log from 4/7/18 1pm to 4/12/18 7:45pm.  that's 70 disconnects. https://goo.gl/Yd44Fn

new update.  had a tech come out on wednesday, and Kyle was by far the most diligent tech to visit.  found water in the line from the pole to the house and rewired all of it, and spent the entire 2 hours working.  the others, well, they've all spent about 10 minutes before saying "yeah it's not working, we'll send someone out".

also stated that there was still a main line issue that didn't seem to be fixed, and turned in a ticket for that, and someone would be by over the next few days to fix it (didn't need to be here).

next day i found a note after work that one had been by and "checked it" and i couldn't read the writing, but sounded like nothing was done other than checking and saying "it's fine".

everything has been A LOT better, though i must say, from 5/9 afternoon until 5/10 afternoon, i had 6 disconnects.  so now over the next few days i'll be seeing how intermittent or frequent the drops continue.
