So i decided to put @johnson Fiirmware on my VMG1312-B10A just to test the new adsl_phy.bin i used he's new latest one which was posted 16hrs ago "1312-B10A-17-jumbo-tel-x6-stats1.1-cmd.bin" and my god it's incredible i literally gained a extra 2mb on my downstream. The only downside which i don't think is a downside my Attenuation increased from 12.5 to 12.8 anyone know why?
I found that Zyxel's one was buggy thank you Johnson you the man ;D I hope you continue to add more upcoming adsl_phy.bin

Attenuation is an estimate only, its normal for it to fluctuate between resyncs.

Thanks Alex :thumbs: Just seen yoour using OpenWrt too i just updated mine just now to 19.07.1

Yup, my line attenuation dropped from 5.4 to 4.3 after power cut next the next resync. it will rise again to 5.4 I used to it though I do not know why it fluctuate with a big difference!!

Fiind it strange that it flucturates a lot i always thought attenuation is how far you are from the exchange? Unless the exchange is constantly on the move. :D

:lol: But in our case as we both are have FTTC, the cabinet would be the moving thing. :D

The actual attenuation does vary seasonally and with temperatue but with a the same modem and firmware anything other than a small change usually means a change in the line.
However different modems and firmwares do give varying values which are just due how the modem deals with the dsl signal. I also found the "x6" firmware gives a higher attenuation but for me a smaller increase in sync of about 0.3Mb/s.

Thanks for that les that's good to know im not the only one but i'll keep this CFW on here cause it's amazing. Especially when it comes to the ES & FEC Errors on the line before i was getting so many errors with Zyxel's default v17 FW then once i swiitched to Johnson's x6 CFW the ES & FEC's have suddenly slowed down.

Attenuation is resistance in the line so yeah, even a small change in temperature causes it to shift. Plus there will always be a margin of error in the detection system, its been suggested some modems utterly fail to detect it properly.

Ah i see it's been freezing cold lately so maybe that's something to do with it. Because don't qoute me on it if there's a shift in tempurature copper can expand and make it look longer than it already is? Not sure if i'm correct or not so correct me if i'm mistaken.
