replacing damaged cable segment didn't solve connectivity issues. what's next?
Hi all, Several days ago I had posted about connectivity issues I was having...I had found a nicked section of my cable outside my house and @Julia_R was kind enough to set me up with a tech who came out in the pouring rain and replaced the damaged segment with a length of new cable. The replacement segment runs about 8 feet, from where the cable emerges from under my lawn to the box where the connection is made to my house. The tech also came inside and replaced a bunch of old terminations in an effort to reduce noise. I have one splitter between the modem/router (TC8717T) and the line coming in. I presume the tech checked the splitter while he was working on the lines and terminations. Anyway, it seems not to have solved my issues...I seem to go about a day and a half just fine and then with no warning the phone and wifi disappear for a few minutes as the modem resets. I have already replaced the modem, and have had a tech (via phone) check/update firmware remotely. OK so here is what my signals currently look like minutes after a reset. They look very similar to what they looked like minutes before the reset (I know because I had been checking), although the downstream channel powers are in the 8's now but earlier had been mid to high 7's. Oh, and at some point several hours ago I had an MDD timeout...but that was the only item in the log for the day.
So what is a logical next step for me? I appreciate any advice. Thanks!
