    You do seem to be having fun, does the DrayTeK at any point say it is in training mode in the UI, if so then I think a call with ISP is needed, to check for line faults, (again) also make sure DrayTek 130 is running firmware 3.8.3 BT

    Also maybe worth looking at ASUS router and see if you can do the following, change the settings of the router to enable baby jumbo frames and an MTU of 1508, see if this helps?

    Alas a case of trial an error 😉

    Can not enable baby jumbo frames only jumbo frames in lan switch control settings.  Can not see any where in Draytek UI that it is in training mode.

     

    should I still change MTU to 1508 in wan setting on router?

    Draytek 130 is running fw 3.8.3 BT

    Just before you do that, when you say you have had the five disconnects, are these every day, or random, I forgot to ask last night ?

    Is this Random, once a week, every few days?

    Glad I asked, In my view, this is perfectly normal, the DSLAM/Exchange does periodically reset connection with modem device, just to refine connections etc, mine is also every other week, and this is regardless of DSL Chipset, I did at one stage (like you I think) have the DSL-AC68U and this re-sync’d almost every few days.

    Does the Synch cause any problems, ie. does this leave router hanging afterwards, if not then I would not worry about this at all 😉

    No porblems just drops connection and reconnects a minute or two later.

     

    I was worried as it never done this with my Netgear setup (D7800)

    Good news then, How did you become aware of the random disconnects, was this by looking in the logs, or via using the service, and then it not being available for a couple of minutes, the DrayTeK and ASUS logs are more comprehensive, where as the logs for the Netgear D7800 are much more basic.

    Either way, just keep an eye on your line stats, to see if over time, the synch speeds changes dramatically ?

    Noticed it on the logs in Draytek and Asus, and once it happened whilst I was home using the internet.

    Can some one check if interleaving has kicked in on my line please?

    my speed has dropped slightly and down stream interleaved depth has increased from 1 to 587.

    Yep! our interleaving has increased – maybe due to weather changes / line condition etc.?

    Your current SNR was 6, now 5, so that is good also.

    I have not had disconnects or any other problems with my line.  So perhaps it is the weather, will it recover and how long will it take?

    It should, but no idea of timescales, best just keep an eye on it over the next week or so?
