Hello,
I recently had fttp broadband 50MB installed and was wondering how I can check my current line speed?
Can I check this through the BT Home Hub 6.

Or you could use the standard https://www.speedtest.net/
If it's FTTP then (currently) BT offers this service up to 300, so they profile it down to 50. So you should be maxing your 50.
