SNR tweaks for Lantiq (DGN3500)

Hello everyone,

i tried to search in the forum but i didn't found nothing

Is there anyway to tweak the SNR margin? My ADSL with the original router can reach 13Mbps (i know it sucks but until fiber isn't here, it's the best i can get)

With my DGN3500 the best i can reach is 11.50, it's not much behind but on a theorical 20 Mbps ADSL, losing 1,5 Mbps it's bad

Thanks!

This thread suggests there is not:-

Downstream SNR offset is supported on my lantiq based BT hub 5 and there's an option in the UI's DSL settings , but I guess it uses a later chip.
