OFDM PLC Uncorrectables
I have an Arris S34 Modem. I had been getting random disconnects for a while, sometimes multiple a day and sometimes requiring a power cycle on the modem to get connection back. I started doing some investigating and noticed I was getting a lot of uncorrectables on channels 193 and 194. I contacted support and ended up getting set up for a tech visit last Friday. The tech found that there was one cable coming from the node to my utility pole with a splitter on it, with one going to my house and the other to my neighbors. So the tech ran a new line from the node to my utility pole to give me my own dedicated line. The cable from the utility pole to my house was replaced 3 years ago. I had a -40db moca filter at my house enterance so he replaced it with a -70db moca filter. After this it goes to a Antronix CMC2002H-A 2 way splitter which goes to the modem and cable box. The cable from the splitter to the modem and cable box is trueCABLE rg6 quad shield riser 18AWG solid bare copper that was installed last year. After this tech visit channel there seems to not be any uncorrectables on channel 193 but channel 194 is still getting a lot of uncorrectables. Is this normal and what should be expected or is there possibly more issues that I shouldn't have? I have another tech visit scheduled for this Friday.

To confirm, have you checked that all coaxial cable connections are hand-tight and inspected any exposed coaxial cable for damage, such as kinks, sharp bends, cuts, or chew marks? Issues like these can sometimes contribute to signal quality concerns and uncorrectable errors.
That said, based on the symptoms you've described, this is likely something that the technician will need to investigate further during the visit.
I also see that you mentioned having a technician appointment scheduled for Friday. Is that correct?
If so, would it be okay if we checked back in with you after the appointment to see how things went and how your connection is performing afterward? We want to make sure this gets properly resolved and are happy to stick with you throughout the process until everything is working as expected.
