T3 timeouts and low upstream power levels

Question

My internet service experiences 2-60 disconnects a week since April 2019. Fixes have been made with varying results. Currently I am experiencing around 6 disconnects a week. I work at home and need a reliable internet connection. Any assistance admins can provide is greatly appreciated.I believe the current disconnects are caused by a "mainline" issue. The negotiated cable modem upstream channel power to the CMTS is very low at 29-31 dBmV. I believe I am at the end of the line, close to an amplifier. I believe this is contributing to T3 timeouts. My downstream channel power levels are mostly fine (see note at bottom of post). My neighbors are also complaining of internet disconnects.The last Cox technician to visit told me the lines are fine, and the issue is either the cable modem or the mainline. I replaced the cable modem that night and I'm still seeing T3 timeouts (though less). Can an admin please increase the cable modem upstream power levels or investigate further?Below is a summary of recent actions/work:All splitters have been removed between the underground cable coming to my house and the cable modem. We do not have cable TV.All coaxial cable between the underground cable connection and the cable modem has been replaced with high quality cable.Multiple technician have been to the house and detected no line issues using high quality meters. They have tested at the "tap", at the "bump", and at the cable modem.3 different cable modems have had consistent T3 timeouts. An old Arris, a Motorola MB7621 (purchased in May), and a new Arris SB8200 (purchased one week ago and current modem).The underground coaxial cable coming to my house was replaced at some point (4-18 years) before I purchased the house.
Also perhaps of concern, the variance of power between download channels seem much higher than typical. One channel in particular (159) is 15 dBmV stronger than the lowest channel power. That channel (159) also have a high number of correctable errors.
Again, any assistance from admins is greatly appreciated.
Below is the current cable modem's spectral analysis and error logs:

I think my issue has finally been resolved. Cox replaced the underground cables from the "tap" to the "bump" to my house.&nbsp; Both the signal to noise ratio and the power levels decreased, but I haven't had any T3 timeouts or disconnects since them.&nbsp; No warnings or error messages on the cable modem either.

Hello. Are there any splitters or signal amps on the cable line going to the modem? Also, has the modem been moved since the tech visit? -Allan, Cox Support Forums Moderator

workingathome12 · Answer

Hello Allen. There isn't a single splitter in the house.&nbsp; The modem has not moved.&nbsp; There are no signal amps inside the house.
