Ultrafast 2 (G.Fast) - Inconsistent Speeds

[sm27650]

Hi Folks, 

I've had Ultrafast based on G.Fast for over 6 months now and over this time, the sync has been fairly stable at 175Mb and downloads peaking at 160Mb of late, but as you can see from the below, it varies wildly on download speeds.

I have a period of consistency and then boom, it's all over the shop or it drops significantly. 

Tests are done from the router every 45 mins (Max interval I can set) - using a Ubiquiti USG and a Huawei MT992 Modem.

Any suggestions as to what's causing the swing?

Hows the packet loss, jitter noise etc been?

Sadly the router doesn’t record that level of information. When I do Speedtest a from a wired desktop it registers 2-3ms jitter and usually no loss.

Anyone? Dropped to just over 100Mb today...

whats your nose margin up and down?

have you done a quiet line test?

I'm unable to access the Huawei model to view line stats. Quiet Line is good.
