To be fair my Draytek has been solid now for some months. I found a forum stating that the Draytek has vectoring enabled and can cause an unstable line, I disabled this via a CLI command and it has been rock solid till now.
I cant remember if i tried my HG612 either lol.
I have also read somewhere the quickest way to reduce interleaving is to cap the line via a CLI command, not that i know what that command is on the Draytek.

What’s your > vdsl status more results, can you paste them here?
Edit: do you happen to have an old AM/MW radio if so tune it to 612KHz and walk around house /outside etc. to see if you have any interference via REIN etc.
For capping speeds via DrayTeK 130, I would cap speeds via ASUS router as I am sure capping a modem cannot help with Interleaving, maybe changing SNR would help, but usually best to let DSLAM do its stuff.
For all things CLI DrayTeK, take a look at attachment

What does RT-AC86U have to do with modem and DSL-failures?

@Grisu – long story but issue is not modem, not all users are as knowledgeable as U and I
– no harm in any user asking (we are a friendly forum) 
@Bully – thanks for stats, all looks as expected, I wanted to see if they was trailing G.INP on your ECI DSLAM, but looks like you are not one of the “chosen” ones ;-)
CAP Router speeds and see if DLM does its stuff for your CRC’s but did notice one of your Bitswaps is off, just checking old post ?
Update; your old stats are the same regarding bitswap, so no change but it is odd why your Near End Bitswap is Off ?
Just checked my Draytek 130 and both bitswap near and far are On, I am on a Huawei Cabinet and checked other posts and they are on ECI and Bitswap is On/On ?
Interesting I think ?

Hi, I updated to the latest Merlin firmware this morning (about 9 am) and since doing so my NE CRC count has gone up to 326598 over 5 hours.
No, my question has been asked seriously!
I dont understand how router update may influence modem CRCs and as he told it occoured on his line. And I dont think it can’t happen, maybe some frequent requests need too much ressources from modem and brings it half way down. There is a lot we cant imagine but happens in reality.

@Grisu – very rare for faulty routers to cause issues with modem synch/stability, but does happen especially with faulty power supplies on routers plugged into same power sockets / extensions as modem etc.
Luckily for @Bully, just bad luck they noticed problem after upgrade, might have been happening before or something caused a power spike with modem (who really knows) ?

@Grisu I thought it could only be the router firmware upgrade as stats and line was solid before the firmware upgrade.
@UK Sentinel – any way to turn the Near End Bitswap back on, or should I leave it off?

I do not know why it is disabled, but to enable try:
“vdsl optn bitswap bi 1 on”
but not sure on exact telnet cmd so check out page 176 of above draytek cmd document and do a backup. just incase

tried the command vdsl optn bitswap bi 1 on but it is still showing as off on the DS.
My errors on the down stream after reboot is staying on 1 count now.
**EDIT** Just checked again and is now showing as enable on DS and US.
Current stats –
NE CRC Count : 741 FE CRC Count : 4023
NE ES Count : 15 FE ES Count : 2633-

Did it say the cmd completed correctly ?

So was it the cmd that work for bitswap ?
Edit: just seen your last post/edit, good news about bitswap being enabled, just remember config will not stay after reboot, to save config you need to do the following.
“vdsl savecfg ” I would leave all alone for a few days and see what happens

Yeah it worked, just took its time in showing as enabled.
