Re: Virgin Business Superhub now has Modem Mode

As I was using the VM Business service I just saw the Superhub reboot and when it came back unable to ping it and the upper blue light was flickering in a different 'pattern' to usual, and then it rebooted again. It has finally upgraded to the BUS_V2.37.13. Supporting the idea that they have been upgraded area by area.

Based on what I read here I am not so sure this is a good thing though!

I did find the SIP ALG option, which was reported to be available with this version, is in the firewall section, and on mine at least, is enabled by default, though greyed out unless the firewall is enabled.

Unless the newer firmware is reporting slightly differently I have noticed a drop from an average of 41-42 dB SNR on the downstreams to:-

Locked 125 299000000 Hz QAM256 0.4 dBmV 38.2 dB 166 0
Locked 121 267000000 Hz QAM256 0.0 dBmV 39.0 dB 164 0
Locked 122 275000000 Hz QAM256 -0.2 dBmV 38.6 dB 161 0
Locked 123 283000000 Hz QAM256 -0.7 dBmV 38.6 dB 177 0
Locked 124 291000000 Hz QAM256 -1.0 dBmV 38.5 dB 186 0
Locked 126 307000000 Hz QAM256 0.7 dBmV 38.2 dB 119 0
Locked 127 315000000 Hz QAM256 0.8 dBmV 38.5 dB 129 0
Locked 128 323000000 Hz QAM256 0.7 dBmV 38.2 dB 131 0

Having said that still happy with the power levels.


I also see extra reports in the network log about the PPP & L2TP sessions:-
