I have Fibre 250. When I connect a device to the hub, via wifi, the speeds I get are very good ie. 200+Mbps. However, after a while, say 5 mins, although this varies wildly, the speed drops dramatically to anything from 60Mbps to 10Mbps.
This happens on multiple devices such as PC's, firesticks, xboxs, phones etc.
The speed on the Hub is always very fast and wired connections are always fast.
Is this a hub issue, or a settings issue?
No. I am not using complete wifi. The signal strength is not the issue, as this happens if a move a device in the same room.
Also, if the speed is slow, and drop the wifi connection, re-connect, the speed immediately goes back to fast.
