I'm looking for some help troubleshooting an issue with an FTTC issue, the connection is currently running at around 13Mb/s stable but occasionally will climb back up to 35Mb/s before gradually dropping back down to the lower speed. As I understand it this is expected but I want to find out where the problem is.
The router is connected to an extension socket and there is a Sky box also connected to this socket with the micro filter directly into the phone socket. There is a phone and another sky box connected on another extension socket which also has a microfilter fitted. The master socket I think is an NTE 5A type although the front plate is blank but when that's unscrewed, the test socket is on the middle right. It was fitted when the house was built in the late 80's but wasn't changed when I upgraded from ADSL to FTTC. The line is rated at 65Mb/s and guaranteed for 35Mb/s
The problem started when I was using a Homehub 5 so I tried changing to a Netgear D7000 which did exactly the same ruling out the Homehub and that is the router that is still connected, I do also have a Draytek 2762 which I'v e not tried as I expect it will be the same. I've tried connecting the current Homehub to the master socket and this was the output:

I then tried connecting that router back to the socket that is normally used:

I've connected a phone to the master socket and both extension sockets to run the quiet line test and couldn't hear anything. The master socket is not very accessible so I can't really leave the router connected there aside from testing.
What would people recommend for troubleshooting, would BT require me leave the Homehub connected for some time? A third party company has fitted FTTP to the street and it is available to the house which I'd planned to change to but unfortunately it turned out they have restrictive policies so thought I'd get back to trying to fix this FTTC issue and get some speed back.
