TalkTalk Fibre 65

I recently signed up for 65Mbps fibre. After two weeks I am getting 50Mbps.
I am 150m from the cabinet and was previously getting a consistent 66Mbps with BT, and nothing has changed on my system.
Using the test socket the speed is marginally up - about 52MMbps.
TalkTalk did a line test and said I needed an Openreach engineer to attend. Before I did that they textd me to say their engineers had solved the problem. That was 3 days ago and there is no improvement.
I suspect the problem may be that the SNR threshold needs adjusting, but TalkTalk just say the guaranteed speed is 48Mbps.
It is outrageous that they advertise 65Mbps, but the 48Mbps is hidden somewhere in the Terms and Conditions.
Do I have any rights to cancel without penalty?

Are you speeds from speed tests are from actual sync rates? What are your stats - what is the SNR/Attentuation/Line speed?

The last time I signed up with TT the minimum speed was clearly stated, I didn't bother reading all the T&C's, but I did read the offer

At 150m from the cabinet you really ought to be getting pretty much 80/20 sync.

What are your current line stats, and can you describe how and what is connected where in the property. (Telephone line wise)

Zarjaz, thanks, I have only one phone connected - to the master socket through a microfilter. There is no audible noise on the handset. The master socket is 2m from the entrance door. There is no dampness anywhere near the master socket. There are two phone extensions to other rooms but nothing connected, and they are not run close to power wiring. The incoming wires are bright and securely connected.

If you have just changed from BT you will have to wait for DLM to catch up and reduce your SNR to 3db which might give you your BT speeds.

IIRC TT specify the middle or most stable of Openreach's line profiles. BT Wholesale default to the Fast(est).

Those two extensions could be why he isn't getting more, and why he wasn't getting higher speeds on BT. (As you are indirectly suggesting ).

He said the extensions aren't connected. You are not reading again.

Reading the post I think it more likely that the extensions are connected but that there is nothing plugged in to them. Perhaps we have different understandings of "There are two phone extensions to other rooms but nothing connected".

Yep, I’d read that as a bridge tap issue too.
