Title: Stats ok billion 8800NL R2 latest firmware
Post by: stevie1978 on Mar 10, 2018, 11:52:00
I live in GL19 4EJ
Are these stats ok?  Is the error rate acceptable the snr is set to 4091.

:welc:

I'm not really one for the technical stuff, but I'm sure somebody will be along with some comments soon.

SNR Margin (dB)   3.6   7.0
Attenuation (dB)   46.0   27.0
Output Power (dBm)   19.8   12.5
Attainable Rate (Kbps)   6752   980

These are the key bits.... What they show is that you have a downstream SNR margin probably set at 3db which is the lowest possible and gives the best performance. Forcing a resync when the SNR Margin is at its highest *might* result in a slightly higher rate but might also bring a little more instability.

Generally the numbers look fine so just enjoy :)

DLM has implemented interleaving on your line as a result of the error count.

You have a downstream error count of 1149, however we can't tell how good or bad that is without knowing how long your router has ben up and whether that is a steady error count of whether the errors are happening at certain times, which might help you analyse what is causing them.

if you're using the d10 firmware,I had an issue with that and went back to the d5 firmware(was provided by billion tech support but never released)which seems to perform better, using the d10 firmware I lost around 8mb on a 70 mb connection,if you'd like to try the d5 pm me and I will send a copy to you
