All modulations are enabled, I guess it switches to the best performing during connect?xazbrat wroteCould be caused by a lot of things, but not really too different ---if you can, tweak how you connect a bit and see if you can connect though a different modulation like ADSL 2, 2+ or G dmt. They may allow you to get better stability and/or speeds. If you have the option, uncheck the others and see if you can connect and see if you get any differences.dany wroteAnd the SNR margin is always fluctuating.
