I'm using the latest official openWRT 18.06.0 r7188-b0b5c64c22 / LuCI openwrt-18.06 branch with my BT Home Hub 5A.
I'm experimenting some problems and slowness with my ADSL2 connection.
In particular, I live very close to my ISP telephone exchange about 300 meters and the quality parameters (Line Attenuation (LATN), Signal Attenuation (SATN), Noise Margin (SNR)) are optimals i.e. they should allow me to reach Max. Attainable Data Rate (ATTNDR) that for my contract are 20 Mbit/s-1 Mbit/s down-up.
My ADSL2 parameters as specified by the ISP:
- G.992.5 (ADSL2+)
- VCI 35
- VPI 8
However, I'm having problem with different ATTNDR values among different connections as you can see in the attached pictures.
What disturb me and the technician of my ISP are the Errored seconds (ES) and the Severely Errored Seconds (SES).
- ES: number of seconds that have had CRC errors
- SES - Severely Errored Seconds - after 10 seconds of ES we start counting SES.
If it is possible, can you suggest me how to reset them in order to monitor the connection?
