Home internet intermitted disconnect --please help!

[Jonathan22]

I have home internet disconnect every 15-20 mins since May 31th. My neighbour using Rogers having the same issue.

I called Fido twice last night but Fido technical support indicate there is no incident or network outage on Fido end.

I reset my moderm but still having the same issue, also same as my neighbour.

I am pasting my Docsis log below:

hey.... i finally find someone with the same issue like me. My issue usually starts around 10am and after 5pm, it becomes stable again. Is yours the same. I also talked to the tech support. I already changed my modem last friday night. I see the exact DOCSIS logs you having. Some config file being rejected, no ranging resopnse etc etc. But when i tried to related the time it went down, it is not exactly the same. I initially thought the modem router maybe crashing due to hardware/software, cause everytime it die, i cannot ping to it. But now i think there gota be something going on from FIDO side.....

[huiraym]

can you tell me if your issue has been resolved and how?

Hey Jonathan22,

Can you tell me if they fixed your issue and how? I have the similar DOCSIS event logs you posted. I somehow thought it maybe some settings change pushed to my modem and causing a conflict and modem crash. If not,  why would it always happen the same time every day.... to me it is obvious that something crashing the modem. They had a technican came and changed all my connectors. I thought to myself if it is the problem with the connectors, it should stop the WAN connection, it shouldn't crashed the modem and making all devices disconnected. To me it doesn't make any sense. They just did that and i will see if i can survive another day..... wish. me luck

Hello Jonathan22,

  Welcome to the community!

  Sorry to hear you're having issues with your home internet. I understand you have already contacted technical support, however, this forum is community-driven and not intended as a venue for customer services. It's unlikely anyone here would be able to go through your DOCSIS log and provide assistance. You would need to re-contact technical support. They would be better able to help sort any issues you are having.

Hope this helps 😀

Cheers
