THIS IS A CUSTOMER SERVICE ISSUE.
My internet connection fails multiple times a say. My modem's event logs stay full of T3/T4 TimeOuts and Dynamic Range Window violations. May gameplay used to clean up after reboots but for the past 3 months, nothing helps. For they past two weeks it has been hit and miss if I could even be connected to a match due to ping rate time outs. (+200ms). My first tech visit was Apr 2020 and they said the main line to the neighborhood drop point was supposed be a temp line and it wasn't buried. It runs along the fence line of several homes and has been there for at least 10 years. The line from the drop point to my house is buried and from that drop to my modem is a single line. Those all checked good in Apr but the main line had issues and was supposed to be replaced. It has not.
This past Tuesday, 17 Nov, I had another tech come out to tell me the same thing, he checked the line to my modem and the one to my house which both checked good. Then he checked the underground access point which he said the signal was out of spec and he also recongnized that their line to the access point should have been buried, just as the previous tech said. I told him about my continous "Dynamic Range Window violations" and how those are affecting my connetion to the internet as well as my multiple T3/T4 timeouts which causes reboots. He suggested that I should lease a modem so that they could better mange my connection, so I did. Not even 30 minutes later I lost internet again while he was still in the truck supposedly requesting a maintenance tickect for their faulty line. I was unable to see anything in the event log of the Xfininty modem because actual errors seems to be suppressed. After about 15 mins later it came back up and he left.
About an hour later it failed again and I was able to talk to an agent on the phone but she was unable to assist me because she said the was an unexpected outage in my area. I explained that when I called there was no such a report and it likely I triggered the report when I called because of the outage. After reviewing my service and listening to my problems, she advised me that she will up channel my problems and she would call me back. I received no call back and my connection failed one more time that day.
With the leased modem, my connection failed again the morning of 18 Nov and by the time I was able to reach another agent the modem rebooted. He was able to tell me that since yesterday there were FIVE OUTAGES in my area and he was unable to do anything until the current outage was cleared. I asked him to look at the notes from my previous calls and see if there was anymore information he would need from me and I also asked him to reinstall my personal modem because even when the system was up, I had better perfomance with my Arris SB8200 than I did with the leased modem. As of now, I am still having issues with "Dynamic Range Window violations" and T3 timeouts. I haven't had a T4 yet, but I have no doubt that I will have one before the end of the day.
Today I had to go into the office to complete my work because I lost internet again!!! It went through 3 more T4 timeouts while I was gone so I called again to give another report. After talking with my 4th agent, she told me that there was no maintenance request made by the Tech on 17 Nov nor was there one entered for my first visit in April. WTH!!!! She also tells me that there isn't anything she can do about that and I would need another Tech to come out!!! To say I'm beyond frustrated at this moment would be an understatement!!! As I'm typing this I get an automated call about how they "resolved an issue that was impacting my service", that is not true, my problems will continue until your service line is repaired.
Here's my Arris SB8200 Modem:
