@JanB5 Have linked the speed info from sky below, there are two parts to this, the speed to your hub over the Fibre connection, and then the speed to your devices, variation on the devices can be very dramatic if wireless connected, a lot less variable when wired, and then finally is the device good enough to maintain a high speed wireless wifi connection!
My phone a Samsung Android A54 syncs at 1200Mb/s on the network, but a speed test will throw variable rates, so basicalyy do not trust it, my laptop way better nearly always hits my FF500 connection at 500/70 rate, Ethernet never fault's at all and rock solid! EVERYTHING gets serviced, so if a slow wifi device jumps in demands data it has to be dealt with no matter what!

Samples from just now and yesterday so you see, just look at the date/timestamps!
