Re: Higher line attenuation & lower speed after BT Hub 6 Firmware upgrade to SG4B1000E020 on

Will be interesting to see how the new router Version with different firmware performs. I did raise this Firmware issue sometime ago and was told it was just a coincidence that the Upload speed went down the day after the Firmware was updated.  There is something about the Line and Signal attenuation which drastically changed.

My upload speeds were always 7 to 8 Mbps and now just over 5Mbps.

Look forward to your tests...

Data rate:

5.41 Mbps / 41.51 Mbps

Maximum data rate:

5405 / 43222

Noise margin:

6.3 dB / 3.5 dB

Line attenuation:

47.4 dB

Signal attenuation:

19.5 dB / 47.4 dB

 

Used to be like this

7358 / 45739
Noise margin:
4.7 dB / 10.4 dB
Line attenuation:
21.5 dB
Signal attenuation:
0 dB / 21.5 dB

Re: Higher line attenuation & lower speed after BT Hub 6 Firmware upgrade to SG4B1000E020 on

I have migrated to Plusnet Fibre many years ago but still using BT Hub 6.   Following forward update in March 2020 the BT WiFi(FON) is now back on and my speed has dropped from 37GB to 26GB.  Really keen to understand how I could resolve these issues.
