that will be on the modem itselfI've installed Merlin firmware on my asus rt-ac87u, but I can't found adsl log.
I use PPPoE Wan connection type and now need to found SNR UP & SNR DOWN.
On the original firmware I could have found SNR, in System log > ADSL logthat will be on the modem itself
I have a Dlink DSL-2500u that config as brige (so I can't see SNR margins on dsl modem) and I have an Asus RT-AC87U with last Merlin firmware.It sounds like you're using the DSL model, which isn't supported by Merlin
