Multiple T3/T4 Timeouts Causing Frequent Internet Outages Causing Modem Reboots

Just like the subject line says, I am having multiple reboots due to these errors and the result of those modem reboots are changing my modems's password to an unknown one which forces me to do a factory reset. I own my Arris SB8200 so Comcast has no reason to push a password change into privately owned device. I have been trying to call for an explaination for the past hour but after my first call, the automated system asked me if I wanted to speak to an agent I said yes and then it hung up on me. Now it says there's an outage in my area and it kicks me out. It is beyond angering. I Need answers about the outages and the password issues. I already know the Arris pushed an update changing their default password...that doesn't work until I factory rest my modem which I do not want to because I save my event logs for when I finally had enough of this poor service and have break this contract without paying a termination fee. What I need to know is why can't I access my Arris SB8200 modem!

Does this apply ?;

 

The login name is "admin", and the password is the last 8 digits of the modem's serial number. You will then be asked to create a new password.

No it does not.

 

As stated, I know about that already and the default password does not work until I do a factory reset. This is the fourth time since that change to the system that my modem's password has been altered to an unknown one. Each time that has happened, after logging in with the last 8, I change the password to a different one, which is becoming just as frustrating because the password cannot be saved with the browser.

Re: Multiple T3/T4 Timeouts Causing Frequent Internet Outages Causing Modem Reboots

Considering this is the only place I get a respone, I thought I'd add here what I posted in the Customer Service forum:

 

I have been having internet issues for months and the one time I've talked to an agent, they were not able to help me at that time I was told that they will call me back that day at 3pm...that was 8 days ago. Today I am having the same issues and the automated system just says we are sorry, thank you for your call and good bye.  

 

My internet goes out multiple times which forces a modem reboot, which has changed my modem's password to something other than the Arris SB8200's default (last 8 of serial #) password which forces me to do a factory reset and that will dump my system's event log. I save my event log in the event I actually get some technical support for my ongoing issues with this abhorrent service I have received thus far.

...

UNBELIEVABLE!!! I was just on the line with one of you agents who said that they were unable to figure out my problem and that they will transfer me to another technical support person to assist me, you’ll never believe what happened next. It brought me back to the AUTOMATED ANSWER SERVICE TO START ALL OVER FROM THE BEGINNING!!!!!!

 

I will keep you all updated.

 

I am on the phone right now trying to get help but its like I'm in an endless time loop concerning a modem reboot that has ben complete for approx. 20 mins. UHHGGG!!!

Re: Multiple T3/T4 Timeouts Causing Frequent Internet Outages Causing Modem Reboots

Adding to my T3/T4 problems, I now have a 'Dynamic Range Window Violation' RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW; it repeats itself for an  hour with a 2hr break tn starts again. Online gaming isn't possible during these periods because everytime I have a Violation it adversely affects gamelay. Info Note: I have an appt on 17 Nov and I will update then.

Re: Multiple T3/T4 Timeouts Causing Frequent Internet Outages Causing Modem Reboots

OK, so my tech appt was yesterday and it went just as I expected. He checked the line to my modesm 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 closing out the job. 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 this morning 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.

Re: Multiple T3/T4 Timeouts Causing Frequent Internet Outages Causing Modem Reboots

The downstream power is too low and the upstream power is too high ! You should get the techs re-involved until it is fixed properly.

 

Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home.
Good luck !

Re: Multiple T3/T4 Timeouts Causing Frequent Internet Outages Causing Modem Reboots

The problem is on Xfinity's side, the 17 Nov tech said so!!! He said he was putting in a maintenance request but as I'm talking to an agent right now that REQUEST WAS NOT MADE!!!! Now I have to make another appointment with ANOTHER tech so that this tech can make maitenance request.

Multiple Daily Internet Outages Since Late October

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:
