My Internet goes down pretty much the same time every night and comes back on around the same time every morning. Usually it'll go down anywhere from 3 o'clock to 5 o'clock in the morning and then it'll come back up around 8 o'clock in the morning almost on the dot every day.

 

I've talked to our Internet technician probably 20 times over the past three weeks and they have even come out to the house and they cannot find anything wrong. All they keep saying is that I should rent a modem from them which I do not want to because I just recently sb8200 for almost $150. By the time the tech even comes out of course the net is back online. 

 

I really do not know what to do. I noticed something weird in the event logs, that is goes back to 1970 on the log time/date.

 

 

I honestly do not even know what to do at this point, I thought about buying a new modem to see if that even will help and I guess I could always rent one from my Internet company but I feel like since my Internet works 90% of the day that I feel like this is on them and not the modem.

 

Any help would be greatly appreciated or if anybody has had this issue please let me know. I have copied and pasted some of the event logs for today and as you can see the weird dates.

Similar to my problems before I ditched the SB8200 and went back to a DOCSIS 3.0 modem and zero problems since.  Beware of “technicians” from ISPs, especially those who hawk their employer’s hardware to rent while promising to “fix everything today with the equipment I have in the truck”.  Their primary job duty is conning customers into renting hardware and upgrading their system for a bigger bite on your money.  12 “technicians” on 7 on-site visits could find absolutely nothing wrong with my hardware and could offer no reason for the recurring outages and no possible solution other than rent their hardware.    As quickly as I replaced my SB8200 with an Arris SB6190 DOOCSIS 3.0 modem all my troubles disappeared.  My ISP still has no explanation and, to compound the problem, is not even suspicious.

 

I have yet to deal with an ISP “technician” who is more than minimally “technically skilled or trained”; my recommendation is to find an independent tech or one employed by other than an ISP if you want reliable skilled technical assistance.


Hello davecantarero

 

Event logs are meant for service providers to check if there’s something wrong with the signal. I understand your point so I think we could address this in another way than just pointing to your provider. Even though to me it sounds like that behavior could be something programmed like service maintenance, I’d like to check some stuff on the modem to make sure the hardware is properly working.

 

Could you please post a screenshot of the Signal Levels? (here’s a resource to know how to check this: https://arris.secure.force.com/consumers/articles/General_FAQs/SB8200-Cable-Signal-Levels/?l=en_US&fs=RelatedArticle

 

Checking this is important when there’s issues with intermittent connection.
