RCS Partial service and SYNC Timing Synchronization failure

Hey guys, 

I recently had my equipment moved from one floor to another and these alerts have started popping up again, for the last week I can notice the connection hasn't been stable.

I'll attach the modem logs.

 

All levels seems fine (on installation engineer told me that the downstream levels should be between 0-3) but I still get these drops.

Any help is appreciated 🙂

Re: RCS Partial service and SYNC Timing Synchronization failure

Hi jaskeenee, 

Thanks for your post and apologies to hear that you are having an issue with your connection since moving the Hub. 

Checking the account, some of the signals are a little out. This may be causing the issues you are seeing. I would like to arrange for an engineer to come out to adjust things. This should hopefully fix the errors you are having. I just need to confirm the address to ensure we are booking the visit on the correct account. 


I have sent you a private message regarding this. Just click on the little plum envelope at the top right hand side of the page to access your inbox.


Thanks,

Kath_F

Re: RCS Partial service and SYNC Timing Synchronization failure

Hi @jaskeenee,

 
Thanks for coming back to via private message with your information.

 
I have booked you in for the next available appointment. We cannot confirm the appointment time slot, so to view this please sign in to My Virgin Media here: My VM


If the appointment is unsuitable or if anyone living at your property has tested positive for Coronavirus, has been asked to self-isolate or has flu-like symptoms then please reschedule the appointment on the same link. 


Lets us know how the appointment goes. 


Take care.
