Am I wasting money on "EXTRA"

[#1]

An update on my question. After help from PlusNet I found that the engineer who installed my Fibre had not done  the job properly. He had told me my existing 12m phone extension lead was OK and after tests it was shown that was the cause of slow speeds. I got a £10 refund and advice to connect my modem to my router by an RJ45 cable. I did this today but the speed is unchanged. I have raised the matter with PlusNet as I hadn't closed my question, but I wondered if anyone here could say when I might see my estimated speed which is around 66?

What is the IP Profile reported when you run the BT diagnostic speed test?

The profile on our end dropped down after the engineers visit but I've increased it now.
If you log into your router and disconnect then reconnect you should get a increase in speeds.

Done that.....
Thanks.
Speed on Speedtest.net now 53.94 and 16.13.
I was told to expect around 66 minimum.
Is a further increase likely with use?

If you there is power near the master socket a simple solution would be to put the modem in to the master and then run an Ethernet cable to the router - that can be up to 100M with absolutely no loss of performance.
