hi orly.

it depends how you configure the modem...

this one has just a single rj45 that's plugged into LAN1.. but i took it off fast bridging and obtain the ppp interface on the huawei itself.

hi griff,

i've got some simple scripts which take the output data from the xdslcmd info --linediag command and pipe it to the open source gnu-plot tool [2]. Gnu-plot uses the data to produce line/bar graphs out of them.. the graphs looks something like this [2]. they might show something interesting.

Here's another screenshot showing the increase in errors since my original screenshot an hour and a half ago -

As for the infromation you asked me to obtain via Telnet I'm having a problem. I've installed the Telnet client in Windows 7 and I've set the firewall to "low" in the modem CP but when I attempt to connect to the modem it tries and fails saying a connection could not be established. Something I'm doing wrong?

Cheers for the screenshots, griff_90!

You can (and should) leave the firewall on "Standard" (or higher). Set the level too low and rogues can log into the device from the WAN-side. That said, if the firewall level is set back to "BT" then it will lock the device again!

I'm afraid don't know much about Windows 7. I have used the putty telnet (and ssh) client for Windows. That seems to work fine..

As for interpreting the figures, please don't look to me for an explanation as I know next to nothing about line statistics... But there are plenty of experts on here who do!......

cheers.

Thanks Orly!

hmm.. wonder where your bandwidth is being lost.. don't suppose you fancy getting a telnet shell and issuing

# xdslcmd info --pbParams and
# xdslcmd info --linediag

cheers

I raised the firewall level from low to standard and that seemed to do the trick -

Does that look like I'm connected via telnet correctly? What is the exact command(s) I need to enter?

Yeh! You're in!

At the ATP> prompt.. you need to get a shell.. and then you can run those two commands..

If you want to save the line stats data and there is loads of it, then putty should be configured to log the session to a file.. the saved data file can be used to generate graphs..

P.S. the telnet shell is configured to automatically log out after a very short period of inactivity (~60 seconds).. this is infuriating(!).. there is a way around it, but it involves recompiling busybox..

Hi orly,

Your stats are really interesting to me.

I am a bit further from the cabinet than you are, & my download speeds are a bit slower than yours.

Have you always had those sort of download speeds since FTTC was installed, or like my connection, did they start off much higher for a while (say 34-35Mb) & have deteriorated over a period of time?

Others at 600m from the cab like you seem to be achieving much higher speeds, more or less the full whack with stable connections in most cases.

As mentioned by asbokid, it would be really interesting to see your stats from telnet & xdslcmd to compare with others & see where the issue might be.


Pauline.

Thanks! It worked fine!
