Got issue today, after remote reconnection(seems done by DSLAM) my upload speed went down from 1035 kpbs to 750 kpbs.


So i have Current sync stats:

DSL Mode: ADSL2+
DSL Channel:
DSL Upstream Rate: 754 Kbps
DSL Downstream Rate: 12327 Kbps

Down up
DSL Noise Margin: 12.2 dB 12.8 dB
DSL Attenuation: 26.0 dB 13.9 dB
DSL Transmit Power: 18.6 dBm 12.4 dBm


But just day ago it was:


DSL Upstream Rate: 1039 Kbps
DSL Downstream Rate: 12430 Kbps 

Down up
DSL Noise Margin: 12.1 dB 12.7 dB
DSL Attenuation: 26.0 dB 13.9 dB
DSL Transmit Power: 19.3 dBm 12.4 dBm 


And telecom speedtest gives me resuilt in 0.64 Mbps, and it was 0.92 Mbps before.


I didn't change modem/router, settings, line, phone, filters or anything else. Rebooted router just week ago, and i had good speeds: 12350/1025 or something. 

Line attenuation and noise margins didn't change.

Is it any possibility to fix that issue? Because it's huge speed difference.
