High Latency Spikes

Hello,

Lately, I've been dealing with high ping spikes to the point were it's unbearable ever since the installation two weeks ago. The download and upload speeds are fine but it's latency is abnormally high and fluctuates through the day.

I've rebooted the router many times and also checked if my area was having issues but no improvements at all.

Hi @Anonymous 

Thanks for posting and welcome to the community. 

Sorry to hear of the broadband issues. From a system check ran, you have got an SNR issue (signal to noise ratio). F010337396 is the fault number for your records. The estimated fix dte and time is the 27th February at 3pm.

Please monitor the connection after this time and report back if any issues, we'll be happy to help.

Best wishes,

Hello,

Went to go check the connection as of right now and there is no improvement whatsoever. The problem hasn't been fixed yet.

Can't open that BQM but if it's the same as the previous one there's probably still noise there. 

Can confirm by looking at the logs to see if the upstream profile is repeatedly changing rapidly - that's the system trying to compensate for the noise.

Oh if this ain't a perfect example for my two solutions. So you've had an engineers out, they 'fixed' it but it still poopy connection huh? Welcome to the world of VM. Your two options now are:

1) Accept this is as 'good as it gets' and get used to it

2) Leave and move to FTTP.
