Hmmm ... you were asked for your router stats at the start of your problem. End to end data speed tests can not discern the difference between WiFi, internet and server performance issues. Router stats clearly report the performance of the part of the service BT Openreach are responsible for (which determines liability for engineer charges) which is the back of the phone socket (test port) to the exchange. Everything else is someone else’s responsibility - phone socket face plate, connecting wires, router, WiFi and hone devices are all the customers.
Did you get the same or a different router?
What devices did you experience problems with? Done have really bad performance issues where there’s dual band WiFi using the same SSID.
