i am 80 meters from cabinet, checker shows 71 expected on vdsl2 , i can order gfast 300 expected 245, but will i have same problem

Go for G.fast please! It very good and more higher speed than VDSL2 because G.fast got Vectoring on it. You will get 330/50 easy as you saying u are within 80m away from the cabinet. You are more likely to stay above 330/50 for a very long time! Never drop.

I am connected to G.fast 160/29 but the line max is 210/29. I am about 280m to 300m from the cabinet. G.fast have two products either of your choice 160/30 or 330/50.

Your estimates are good, and your line is well below the handback threshold.
The low sync may not just be crosstalk.
The checker certainly seems to think you should sync higher and it takes crosstalk into account.

If there is a line issue causing low sync then that would be carried over to G.Fast.

If it is entirely due to crosstalk that you're syncing so low on VDSL2 then switching to G.Fast will definitely help.
There's 300-400 active VDSL2 lines on many cabinets (over 550 on mine), usually with no Vectoring.
The G.Fast DSLAM's are much smaller and take up is low. It has Vectoring (it's mandatory on G.Fast) so crosstalk would be less of an issue.

As you're below the handback threshold your ISP should be willing to send OpenReach to check your wiring and try improve the sync speed.
They've done that with no success it seems.
If the current low speed issue is the DSLAM ports or the line card then G.Fast would bypass these issues.

Here’s another vote for g.Fast … I’m 140m from the cab, and get a 330/50 sync with a theoretical max of around 400.

A nice low ping … it’s all good for me

Here’s a cheap and dirty speedtest over wifi to my iPhone XR ….. the router is two floors below

The estimates only guessed. Your line can easily get 330/50 with max line maybe over 500/90 pretty very easy with that short distance to the cabinet 80m away. The bloke is 140m away and got 330/50 (max line 400/70) and I am 280-300m away and I get 160/30 (max line is 210/30)

Unless you're lucky enough to have a BDUK funded cabinet that's got vectoring.

Or you're just lucky. My speed has improved over the last couple of years and for a while last year was nearly back up to full speed. It's fallen back a little now but it's still faster than it was two years ago. Maybe one of my neighbours has cancelled their service.

Some cabs they replaced the original tie cable with cat5 grade cable to reduce the effects of crosstalk.
Some of the originals tie cables were not terminated correctly or the strips were damaged or crack over time and many have been replaced/ reterminated.

thankyou all for your comments, this has today been sorted, my isp "zen" booked a third engineer visit, surprising he reported back no error found but interestingly i am now syncing at 75 meg RESULT

That's good to hear it but what if the problem come back again? Then go for G.fast instead.

Comes down the same copper from the cabinet max.

Yes I know that. But I do think the engineer haven't fix his line because more likely resetted DLM back to 75meg but it probably will reduced again if cross talk still issues as g fast does not affect by any crosstalk
