I would just like to have if at all possible some input from the knowledgable
I had FTTC enabled in 2012 I was with ADSL24
These are some stats I gained from the HG-612 modem shortly after install (engineer installed HG-612) but not the one I swapped to get stats

The above (i only plugged in zyxel (bought 2nd hand on ebay recently) just to get stats as I have been using the ECI modem for the last 5 months
When sync started going south again last year 2019 (recently) I changed my engineer installed hg-612 for another hg 612 then found out cab was ECI so bought b- focus v-2Fub/r Rev.B and left it on 11-Sep-2019 02:29 to try and get sync rate back up in case both my hg 612 had gone faulty this stayed synced at 60143 from 11-Sep-2019 02:29 till 24th jan 2020 when i had a powercut and upon the power being restored modem was synced at 68438 this only last till 27th jan 2020 and then it dropped to 52071 on the 27th jan 2017 as can be seen in attached image (if they are working )
Current ISP is zen
This is what adsl checker says now
I'd just like some advice as to what my line should be able to actually do now as it just keep syncing lower and lower and anything I can do as I don't want a charge from sfi2 visit as zen are saying there is no fault when they do their line test and they'll book an engineer as long as I agree that a no fault found by engineer means I have to pay.
OR install in 2012 installed hg-612 as well as a new filtered faceplate with tel and rj111 sockets (same one still) I do not run any extension only phone in house is on same socket and I replaced the phone recently as well in case old one had issues. I used a billion 7800n with this for many years until it started having trouble so I replaced it with r7000 with xwrt-vortex firmware and also bought another 7800n new which i have tried as well
