Hi @Beth_G, thank you for having a look. We will look at switching over to the router mode of the super hub 3 so you can run more complete tests after the Christmas period is over.
However I have had the opportunity to set up a more complete testing suite on our side and after analysing some local traffic I can replicate the latency spike. Here is an example of a persistent latency issue that we saw above.
And here is a triggered latency issue for a few minutes:
The latter of which occurred while continuously uploading to the internet (I have tested this locally and there is no latency impact when copying to/from a local server at 350Mbps).
After which I can across this buffer bloat test showing just how extreme the increase in latency is while uploading:

We are on the M500 package (so in theory 52Mbps upload) but something we see only on occasion.
In theory SQM (which we have and is "automagically" enabled) should help but with such varying bandwidth it seems pretty difficult to solve. Maybe something like `autorate-ingress` in openwrt would help but this is definitely a plaster to cover a bigger upstream problem.
Thank you for that information. If you can please let us know when you have been able to take the hub out of modem mode.

Thank you @Martin. I will change it on Tuesday (working hours) for you to have a look at (unless Saturday/Sunday/Monday works in which case let me know).
Just coming back to share some additional latency graphs from today which has had two particular bad periods (during which time there was limited local traffic on the network). The below graphs are for Facebook but true for any outbound traffic.
Also would encourage anyone who is facing similar issues to use SmokePing for long term monitoring (with a very low polling time, we are using 3 pings every minute).
Hi StillHoping
Thanks so much for popping into router mode for us. We've had a look at the data across Samknows and our internal systems and we can't seem to see any issues at all. All your power levels are in spec. Your speeds to the Hub have been very consistent and there's been no disconnections logged over the past week.
We really appreciate you providing the data recorded from SmokePing, however would you please be able to start a Broadband Quality Monitor graph so we can monitor your broadband performance that way?
Let us know 😊
The hub has been switched to router mode. Thank you for looking into it and please let me know when you are finished!
