old firmware 1.1.2.3_805 good except wifi Snr auto 8 dsb ? How’d I fix it fixed
Understood – Are you using ADSL or VDSL as they are different to adjust SNR
is 8 SNR, is it to low/high for you ???
VDSL – To fix SNR at 8 dB, go to Administration > DSL Setings (Stability Adjustment) and choose 8dB ?
ADSL- will depend what your current SNR is ? (usually used if connection is unstable) to increase SNR value
e.g, current SNR = 7dB and you want 8 dB, choose -1 dB from ADSL Stability Adjustment
7 – ( -1) = 8 
(if my memory serves me well)
