Intermittent connection - SYNC Timing Synchronization failure & RCS Partial Service

Hi community,

I am on my end of any solutions here. 

My internet started to keep drop in the last 2 months, it worked smoothly before and without any loss. I am experiencing everyday drops ( working from home/ losing my connection) also gaming and kicked out from the sever at different times of the day

I tried already to check cabling, restarted the router several times, factory reset. I thought it was probably that I've got around 15 wireless devices connected to my HUB 3.0 and it cannot keep it up, but this was not the case, because I bought a Netgear Nighthawk XR1000 , placed the HUB 3.0 into modem mode, and it still happening ... I am at the edge of my powers in here as I don't know what to do anymore. Called VirginMedia several times, eChat aslo...begging for an engineer visit, but I was just told that "no issues found in your area" etc . 

I placed back the HUB 3.0 in router mode so I could create a monitor via thinkbroadband so I could share with you.

Also I will paste here the logs from the Virgin Media 3.0HUB.

Hi DenisC,

Thank you for updating the thread, I am sorry you are still having issues, I know this must be frustrating.

I can see from our systems our team has been in touch have they managed to get you some answers on this?
