Lag spikes - BQM sawtooth

Joining in


Since the beginning of installation we've been experiencing lag spikes (from ~22ms to ~300ms).

They occur everyday.
Lag spikes hit us at the same time most of the times, however sometimes they affect just one of the PC.

We're both using PCs, connected via WiFi.
Connections to the router: 12 devices - 2 cameras, 2 PCs, 2 Phones, 2 TVs
"Channel Optimization" Enabled, Dual band 

The speed otherwise is perfectly fine and there are no other issues.
No problem with download etc.

Yup VM like to DoS your connection with unnecessary speed tests.

you have to wait for modem mode or ask them to turn auto speed test off which they don't make easy

Someone suggested this ends after a few weeks, I've been on XGS pon for months and my graphs are still like this.

Just had a call with the support.

They do not see any problems, they do not understand what "lag spike" or "latency" is.

They told me the will monitor it for some time, but I just assume this will go nowhere.


Hi ppozniak,

We are really sorry to hear you weren't able to get any help when calling the team.

We'd love to help further, but sadly cannot with your specific equipment.

What we can do is pop a note on our end to explain the issue, so when you call the team again, they will have a better understanding of what's going on
