RCS Partial Service/SYNC Timing Synchronization failure

Hi,

Over the last few weeks my internet has been experiencing intermittent internet dropouts. The dropouts have been to all devices, wired and WiFi. Sometimes it is absolute fine but recently more often than not I am experiencing constant blips in connection and very poor speeds. 

I've checked the network log for the Superhub 3 and have constantly been receiving the following over the past few weeks:

I've also been keeping a BQM over the last few days:

06/07/22

My Broadband Ping - VirginDropouts

07/07/22

My Broadband Ping - VirginDropouts

08/07/22

My Broadband Ping - VirginDropouts

 

I've tried all the obvious things, checked the cables - all look fine. Tried restarting etc. but it makes no difference. 

A similar issue to this did happen a few years ago and a technician came out and fixed the box down the road from my house so I'm wondering if a similar thing needs to happen here.

I've spoken with Virgin Media call center and I get no where with them and they just tell me it will be fixed within 24 hours. Someone advised me I would need to pay for a technician to come out, he even tried to advise me that a 100Mbps wasn't fast enough for online gaming 😅

Hoping the online team here can help arrange a technician to take a look at this issue as some days its unusable.

It may well be the local cabinet again. The BQM and errors point to peak time packet loss and sync issues.

Check for local issues on 0800 561 0061.

Also post the hub stats by going to 192.168.0.1 and clicking the link that says Network Status below the login fields.
