There are a few candidate formulas, some better than others..

A simple average could be calculated. It would be based on the sum of the attenuation calculations for the utilised frequency bands, and calculated separately for each direction. It wouldn't be very meaningful combining the attenuation figures for upstream and the downstream bands.

Alternatively, the attenuation could be apportioned according to the number of carriers in a given band and the bit loading for each carrier in that band. This metric would capture the impact of the attenuation on the quality of the connection.

The fact that the HG612 modem doesn't present an attenuation figure in its web interface could mean that Huawei hasn't got the answer either!

If I manage to screw up the courage to see about getting into mine, I know the attenuation reported by the JDSU.

By the way disabling the QOS on the BT modem has got me another 1mbs throughput on speed tests.

I'm a bit confused by this (easily done tbf).

Although by default QOS is enabled there's no actual policies in place is there?

Can I suggest re-arranging that to read 'If I manage to get the courage to see about screwing up mine'

I have done two modems RobertoS, It's a piece of cake.

Before doing this set the IP in the nick to 192.168.1.6 to be honest you can use 192.169.1.2 all the to way to 254.

Subnet to 255.255.255.0

Default gateway to 192.168.1.1

When flashing leave the upload to do it's thing don't be put off if the upload page times out it's normal and the modem will reboot it's self, then it's done and login.

I think you will be fine to be honest.

Disabling the QOS gave me another 0.5mbs on the download and a whole 1mbs on the upload so it's deffo worth doing.

I have done the same thing on my mates modem and got the same results.

Cheers asbokid, that seems to have done the trick for me and I can now access the modem and all the menus. Managed to pull the following stats:




Attainable rate (kbit/s) 47232 15962
SNR margin (dB) 11.1 22
Line attenuation (dB) 0 0
Output power (dBmV) 10.4 -23.1


Line rate (kbit/s) 39999 9995
CRC errors 0 0
FEC errors 0 0
HEC errors 0 0

I have also gained an additional 1Mbps of upload speed by disabling QoS on the modem.

Finally got in Trial and error and a few reboots later.

Thanks again to all the posters for their help.

My line is not great however 1.3 miles from the cab I cant complain. Unfortunately my IP profile has dropped because of the reboots so hopefully it will pick up soon.

The QOS has been switched off so that should help my speeds

Thanks again

What was your guess speed on BT and what is your distance to the cab?

Can you post stats from Telnet also please.

Edited by lockyatlrg (Sun 11-Sep-11 14:53:07)

My guess was that I was connected at 40/10 as I am 113 meters from the CAB. My actual throughput is around 37/8.

What I mean is what was the speed BT wholesale checker gave when you was ordering FTTC.?

Mine was 32/7.5, I am 350 meters from the cab by road and probably line length, cab is about 100 meters straight line distance.

Also any Telnet stats
