Tried going through customer services and they have repeatedly said there's no problem or it's just due to external factors... Personally I believe there's something else going on.
Periodically we will see extreme variation in speed, ie from ~100 down to 10-20mbps, across multiple devices.
I have set up a BQM (ignore the large packet loss at start of the graph, router reset)

Replying as this may be useful for anyone seeing similar problems..
This afternoon the wifi-cards completely gave up, ie hard-wired devices could still connect to the hub but Wifi devices could not despite the SSID still being broadcasted. On call to support the agent said he could see a lot of congestion, so suggested the following fix:
We disabled channel optimisation and set the channels for both bands manually, channel 8 for 2.4ghz and 104 for 5ghz. We also did a push-button hard reset of the router beforehand. The support agent could see immediate improvements in the amount of congestion, and speeds/signal strength appear to be much better.
I wouldn't be surprised if the wifi-cards installed in these hubs are fairly low quality (compared to commercial grade APs such as Cisco/Xirrus)... but I guess that's the wonders of mass-market for you 🙃

Welcome to the community @mikewebbdev and thanks for taking the time to post on here on the forums.
I have looked into your account and cannot see anything that would be causing this either with your individual connection or in your area.
Would you be able to answer the questions from @jbrennand as this will help is determine what the issues are and how best we can fix them.
Regards,

Just speed fluctuations, only evident on wifi connections afaik, Hub light stays white. I have also checked the connections and all are tight, and no evident kinks/faults in the cables.
From the table below it looks like the 2.4ghz is not running on the correct modes? 802.11n should be capable of higher speeds than that even with a number of devices...
Also worthy to note that M-iPhone and Desktop are both in the same room, as are K iPhone and iPad... so I don't think that it's any signal interference or external factors causing the speed difference.

Today's BQM is also showing a lot more latency peaks than normal

Hi mikewebbdev,
Thanks for coming back to us on this.
If this is only happening on the WiFi then a little optimisation of the connection may help. Try these help pages for some advice:
You may find splitting the bands beneficial but you will need to connect to the WiFi on the best band for the device you are connecting. It can be a bit tricky having to try out a few things so a few tips:
To split the networks, just follow these steps:
*Make sure that both frequencies are named differently and are still identifiable
Give that a try and let us know how you get on.
Thanks,

Thanks for your reply and update, mikewebbdev, has the reset got everything sorted for you?
on 23-07-2021 16:38
Fingers crossed, it should be!
