Ever since the "free" upgrade to higher Infinity speeds we have suffered with frequent restarts of our HH5.
I posted previously and the focus appeared to be on the SNR numbers but with a general concensus that the DLM would eventually sort it out.
Unfortunately this has not been the case and I am now resolved to sort this finally. My son is often "live streaming" his own channel whilst gaming and is very unhappy about the frequent crashes and wants me to change providers.
If anyone is interested in helping I'm happy to post additional stats, etc. To give some context, here are the latest entries in the log. I've calculated an average continuous uptime of 1.4 days since 20th March. The longest was just over 5 days and the shortest just over an hour.

Spoke with BT Broadband Support (Alex) and he said he could detect interference from his end and he reset something. I was then asked to restart HH5 although before I got a chance it disconnected and restarted itself
Since then it has already crashed again twice in 24 hours.
The key stats show as below. The noise margin numbers have been like this for months. Should they be higher?
1. Product Name: HomeHub5
2. Serial number: +076286+1542003477
3. Firmware version: v0.07.06.01239-BT (Type B) Last updated 7/3/2017
4. Board version: 01
5. VDSL uptime: 0 days, 14:28:38
6. Data Rate: 14381 / 74833
7. Maximum Data Rate: 14381 / 75354
8. Noise Margin: 6.0 / 3.1
9. Line Attenuation: 30.7 / 22.0
10. Signal Attenuation: 0.0 / 0.0
Thanks for getting in touch. I'm sorry that you are still experiencing problems.
I can't understand what the adviser Alex could have reset on your fibre connection. I'd like to get this looked into for you. I'd like to ask them directly. Before that, can you go to Connection Problems and make sure you follow any advice there? Come back to me when you've tried those tips.

It would be fantastic to make some progress on this.
I am a reasonably savvy user (I've been in IT for 40 years) but not a VDSL expert.....
My setup is BT connection direct to my study. I can see the cable coming through the trees.
I have a VDSL faceplate bypassing any extension wiring with a direct connection to my HH5.
From there I use a combination of wifi and direct connections (Cat5e) around the house.
I've checked out the BT link you supplied and don't believe it added any further value in my quest for a solution.
What other information do you need to know?
I've restarted my router manually again as part of the testing and the salient details are:
6. Data Rate: 14418 / 75058
7. Maximum Data Rate: 14459 / 76121
8. Noise Margin: 6.0 / 3.3
9. Line Attenuation: 30.7 / 22.0
really surprised your conenction speed is stail as good as it is - almost at attainable - whereas normally your connection would have been banded by DLM and probably down about 40mb or lower
is there any noise on quiet line test dial 17070 option 2 should be queit and best with corded phone if quiet then get mod help as you need an engineer visit
Quiet line test on corded BT phone perhaps has a little hum to my ears but not sure how quiet it should really be.
We'd sacrifice some speed for reliability but don't appear to have any control on that.
What triggers DLM? Do the router restarts make this happen or do we have to actually power down frequently?
the quiet line test with corded phone should be quiet and you only hear the announcement - no hiss/crackle/hum
the DLM normally takes action when then line is unstable just like yours and starts to increase noise margin and drop speed to try and stabilise the line - that is not happening in your case
Not sure if it helps but I see others get asked for this info:
