      Why does my line attenuation drop from 54.0dB to 15.5dB after router reboot?

      How is this possible?!
      Line attenuation should be pretty much fixed shouldn't it? It relates to the physical line length.

      Here is my stats before router reboot:

      Down Up
      SNR (dB): 8.1 14.0
      Attn(dB): 54.0 31.5
      Pwr(dBm): 19.8 1.2
      Max(Kbps): 6880 1120
      Rate (Kbps): 6272 416

      Here are my router stats after the reboot:

      Down Up
      SNR (dB): 8.1 13.0
      Attn(dB): 15.5 31.5
      Pwr(dBm): 19.8 1.6
      Max(Kbps): 6880 1088
      Rate (Kbps): 6272 416

      Can anyone explain this huge drop in line attenuation please?

      I'm on g.dmt, with interleave.

      Thanks.

      15.5 is a known bug.

      Simply reboot your router a couple of times till it clears itself.
