Adnan wroteI had the same experience switching to G.dmt. You have a higher snr margin so bursts of noise can be tolerated.
Can you post the following ?
-Your SNR margin during different times of the day on G.dmt.
-Same on ADSL2+
-Your data rate for each.
-The times or the time intervals you notice the errors.
-Your modem model and revision
Nothing changed much honestly between both modulation types except for the CRC errors. As I said when gaming I get like 1000s of CRC errors per hour while on G.dmt I get <50 CRC errors. I took the screenshots after immediate reboots of the modem so the errors are 0.
