The speed guarantee is the connection speed to the hub and not to devices. Are you speed testing via WiFi or Ethernet?
Wifi but should be getting more even over wifi
this was a rough speed guide on forum previously
As an example of what I mean in terms of devices not being able to support the full breadth of speed available on Full Fibre 900, take a look at the table below. This is just for a couple of Apple Smart Phones and Tablets along with popular Samsung models,
Apple (Smartphones) | Dualband (2.4 & 5Ghz) | Theoretical Max speed on 2.4Ghz connection | Theoretical Max speed on 5Ghz connection |
IPHONE SE | Yes | 60mbps | 300mbps |
IPHONE SE 2020 | Yes | 135mbps |
600mbps |
Samsung (Smartphones) | Dualband (2.4 & 5Ghz) | Theoretical Max speed on 2.4Ghz connection | Theoretical Max speed on 5Ghz connection |
galaxy-s10e | Yes | 135mbps | 600mbps |
galaxy-s10-5g | Yes | 135mbps | 600mbps |
Apple (Tablets) | Dualband (2.4 & 5Ghz) | Theoretical Max speed on 2.4Ghz connection | Theoretical Max speed on 5Ghz connection |
IPAD pro 3rd gen (Nov 2018) | Yes | 135mbps | 600mbps |
IPAD pro 4th gen (March 2020) | Yes | 135mbps | 600mbps |
Samsung (Tablet) | Dualband (2.4 & 5Ghz) | Theoretical Max speed on 2.4Ghz connection | Theoretical Max speed on 5Ghz connection |
galaxy-tab-s5e | Yes | 100mbps | 300mbps |
galaxy-tab-s6 | Yes | 60mbps | 600mbps |
Ethernet should ensure you get the maximum possible speed but I also appreciate that connecting this way is not always possible
WiFi is also susceptible to interference and therefore can vary at different intervals.
Speed guarantee is the speed your hub receives and not the speed the client device receive. If you want a more stable connection to the client device it's advised to have a wired connection to the hub.

You can try fine tuning your WiFi settings and to make sure your on a more clearer band. One thing to note is to check which frequency your devices are connecting to. I've noticed apple devices aren't that great jumping between 2.4 and 5Ghz. The device should also show what bandwidth it's got for both up and down over WiFi
I do understand, however, when my phone got 14mbps, while in the same room, that has to be an issue, restarted my phone it jumped to 150, but shortly fell again.
also just to add, ended up moving wifi disc in my room (uptairs) seem to be hitting 140-150 seems stable.

Hi imjolly
"Ethernet should ensure you get the maximum possible speed but I also appreciate that connecting this way is not always possible"
Please note that with older hardware the device may not be able to cope with the LAN speed. For example I have a PC which is a few years old with an MSI motherboard. Using the built in LAN connection causes the PC to start crashing at speeds approaching 900Mbps
