Very poor BQM & bad pings: Utilisation Fault?

[cje85]

Hi,

Recently my BQM graphs have been looking really bad, and i'm noticing my connection is unstable in the evening. Things like WiFi calling, video chats and gaming are being ruined by unstable pings.

Are the forum team able to check utilisation levels in the area, or check for any other problems? VM had an issue with high utilisation a few years ago in this area and this is starting to feel very similar. 

Here are my most recent BQMs (although there's at least 6 weeks worth of awful graphs I could post) along with modem stats.

I presume the over-utilisation 'SNR fault' is still ongoing?

Latency is horrible:

Can a SNR fault cause high ping on the upstream? Like the modem is about to send something then noise happens and the sending aborted and is delayed for next time?

Good morning @cje85 

I am afraid not, the fault reference is F010948446. The estimated fix date is the tomorrow at 9am.

Best wishes.
