Cable modem error issues

Greetings all,,, after some extensive troubleshooting,,I have come upon a possible source of my cable modems high uncorrectables , my neighbor next door also has Xfinity service. I remember during the Covid situation that he had Xfinity service installed, there were 2 men with shovels making a shallow trench from the pedestal to his ground block. The coax cable they used was orange in color, my guess is it may have been direct bury RG6, no conduit, just the cable and the dirt to follow. I know when I had the tech come out in April to evaluate the situation, he removed the pedestal cover, inside were just 2 coax cable connections….my neighbors (in orange) and my old drop ( black…dual shield ,,direct bury ). Since about the 22nd of this month until this afternoon, my cable modem was at zero issues. My neighbor came home, started leaf blowing and now the modem once again has errors. Now I do realize this could very well not be the problem,,I thought I would share the info,,,,and by the way,,I downloaded the modem’s diagnostic info since the 22 nd.
