Max, please listen to Kitz and also allow it a few days. If there is any instability, the DLM will adjust the parameters as it sees fit. If it is a case that 3 dB is too low, it'll increase it (in 1 dB steps). DLM seems to act not too long after midnight at the moment for me.

In reference to the response from the ISP, I am guessing they would need to prove there is a backhaul issue so they could get out of the contract with their supplier in order to move you over. It is too early to make that call.

[tubaman]

As above, please just leave it alone for a few days. It's a new service and DLM will be adjusting to get the best parameters for it, and if you keep changing the modem etc it will not help with the process at all.

I have leave Openreach Gfast Modem and TP link Router alone before few hours (midnight) as it seem all stable now. I can see LIVE BQM is much better. All household wireless are fine getting closer 150/29 same as ethernet pc.

Will leave it alone!

I put Zyxel Gfast router away in the cupboard but like all of you saying leave it alone. My isp will monitoring it.

Updated:

My daughter and i agree it all settled down as it seem Zyxel didn't work out well (don't know why) but the main things Openreach gfast modem with TP Link no issues so far on both ethernet and all devices in the household for wireless (both on max speed) and BQM much healthy now.

So, I am not using Zyxel for now - staying in the cupboard otherwise I could end up more issues and DLM won't like it.

Your tracert is good and I don't see any problem with the latency on ethernet.  Which is what you want.  Wifi issues can be sorted later - they are not the ISP responsibility...  but the main thing now is getting that line stable bearing in mind that DLM may make some changes with G.inp depth and 'x'dB.   Any changes will happen after midnight so dont be worried if you have the odd disconnect at around this time.  You have sufficient surplus SNRM so I dont envisage anything drastic happening anyhow.

[adslmax]

Thanks for the warning Kitz over DLM G.inp depth and 'x'dB as long it stay at 160/30 not dropping down to 100/30.

Downstream is fine, its upstream that would reduce a little if it had to increase your SNRm.  Even then it seems likely it would still be faster than VDSL.

Lots of people on g.FAST seem to end up with LESS upstream than VDSL, so I'd count yourself lucky either way.

[adslmax]

Yes very true over very lucky to go above 20Meg on gfast upload same as my old fttc.

Ah well I don't have any stats now (can't from openreach modem as it locked) but who care about stats. As long it remain at 150Meg and above 20Meg upload. I ain't complaint!

Next door been asked me how did it goes I told them I only get 210 down and 28 up as they told me that odd as they getting nearly 290 down and 44 up. But I know one house on the btw checker got a very clean high and low 330/50 two next doors. Seem G.fast very strange indeed. All connected to the same Gfast pod.

The engineer did show me map of the layout cable from my house to the gfast pod as it seem not straight line, it was lots more than VDSL line length as I guess from my old Plusnet GEA test say Estimated Line Length In Metres    243.6 (I guess added another 50.0 make it 293.6 for the g.fast pod to the line socket)?

@Kitz just ran tracert just now from pc all much healthy

You may as well stop checking the checkers too.   But its hardly surprising its changed.    Please do remember that these are best guesses.   
I keep telling you that g.fast uses SRA so sync rates can change on the fly.   It shouldn't really affect you though now you are on the lower product and have some spare SNRM.  Unless there actually is a real problem I dont want to see the btw checker results again.   Forget about them.

Next door been asked me

Max, I'm getting deja vu here.   A while ago I spent a long time plotting out the neighbouring g.fast speeds in my daughters street and showing your the results.   With g.fast you may well all be on the same cab, but its line distance from the cab that matters...  and it matters more than with VDSL.   I must have reminded you of this at least half a dozen times when I've tried and tried time and time again to tell you that even some houses nearer to the cab may have a longer line length than another house further away due to the DP & JB locations.    Some houses end up 'doubling back' - it cant be helped.   It makes not much difference with adsl/vdsl... but with g.fast it can make quite a bit of difference when using the g.fast higher frequencies.   You may be further away from the joint box than he is.. or your line length to the JB may be longer than his.    You can't possibly know.     

It sounds like the engineer has also tried to explain this to you by showing you the plans.
kitz is likely to rather cross if she has to tell you again being on the same cab doesn't matter and it depends on your line length from the underground joint box and if yours doubles back (about 50% of lines do double-back to the DP or JB to some extent or other).   


---
Tracert is looking really Lovely.   No sign of latency problems there.    It doesnt matter if some of the in-between figures are a bit higher.   As long as the end figure is 11/12ms then all is good      

[kitz]

that DLM may make some changes with G.inp depth and 'x'dB.   Any changes will happen after midnight so dont be worried if you have the odd disconnect at around this time. 

btw best expand on thatstatement in order to avoid any confusion with the old & outdated stabilisation period. 
Whilst there is no longer a 10 day settling in 'stabilisation' period...  More recent changes to the DLM in respect to g.inp and 'x'dB do mean that the DLM may make adjustment to these on a new line or after a reset until the DLM has found the most suitable rate for your line.

One more question to ask, the latest BQM are much better and lots healthy than yesterday. I pretty upset that Zyxel wireless has awful issues and don't understand why the wifi drop to below 50 in 5GHz. When changed to Openreach Modem and TP Link the wifi went back to steady 149/27 Very odd.

I think the firmware has messed up Zyxel unstable.

Anyway. I going to stayed with OR Modem and TP Link router that keep my G fast stable plus the wifi stable.

I have inform my daughter DO NOT TURN OFF OR REBOOT OPENREACH MODEM. leave it alone. Just use TP Link Router to reboot if she got wifi issues in future when I am not at home.
