I recently bought a BT Hub 5a which was already flashed on ebay.
Now that I've got it all configured, I'm wondering if it is possible to increase the speed. I was using a Fritzbox 7390 before which could achieve roughly 50mbit/s downstream.
Now with the BT Hub, even after switching to the modem blob of a 7490, I only achieve 20mbit/s.
