How big a bit?

This bit!

Sorry, it's completely different to anything I've seen.

[excossack]

ahhhhh.....

if i use the link http://192.168.0.1/managment or http://192.168.0.1/tech I land at the same page, presenting me with. Here I get a detailed log option if that's the one your after(at the bottom on the LH Side.)

Normally you get to the DSL diagnostic from the MDC ( Management & Diagnostic Console ) http://home/mdc
and then the DSL Diagnostics is on the menu on the left. I believe the default mdc password for singtel is 2wire.

But from those statistics you can see that you have had 34 dsl retrains in 31 hours. That isn't good, I suspect that sometimes after the retrain, the ppp  connection isn't being re-established for some reason.

The one you want is the DSL Diagnostics ( top option in the Troubleshooting section )

[excossack]

Ok.I will grab a screen shot. What info do you want?

[excossack]

here we are, two screen shots. The 2nd one is the rest of the first one.

[MisterW]

Could you possibly post the first one again but with the Time column showing so we can see the time frame.
But as you can see you are getting a lot of DSL retrains and the noise margin is varying drastically ( from 9.0db to -0.2 )

[excossack]

Here it is as requested by popular demand! 

[MisterW]

Ok, thanks.
Well just looking at the first 2 entries:-
shows that the line re-synched at 00:26:39 at a SNR margin of 9.0db but that by 00:40:26 the margin had dropped to 0.9 db and you had > 10000 CRC and FEC errors.
The line is resynching very frequently but its the hugely varying SNR margin that is worrying.
I think its worth trying the PSU just to rule out the router as the problem but my guess is that its a line/card fault somewhere.

[excossack]

Cheers chaps for the replies. I will have a look for the spare PSU.
Would it be worth putting a new firmware onto the router if there is one available?
Next thing is to convince my ISP that I have a fault on the line that only effects one router.

BT Firmwares 5.29.107.12 & 19 are available as is the Quest v6 ( I think!). Beware though, if you update to a v6 you can not go back!. Have a look at the tripod site for all things 2700 http://bt2700hgv.tripod.com/ir1002700HGV.htm

Next thing is to convince my ISP that I have a fault on the line that only effects one router.

I don't think it just affects one router, I suspect it will affect anything that is capable of ADSL2+. The only reason the DG814 works is that its not ADSL2+ compatible and therefore forces a synch using ADSL1. Some ADSL2+ routers you can also force the mode to ADLS1 but unfortunately the 2700 isn't one.

I have just won a replacement router & PSU off ebay for £10. So when then arrives, it could become a victim of a firmware upgrade :-)

if that fails to work as it should then a call to my ISP and see if they can help.

[Rik]

Keep us posted. 

[excossack]

Will do.

[excossack]

Looks like its not the PSU :-(
The new router arrived today, currently running the BT Firmware. I am tempted to try it as is, with my current ISP settings and see what happens.

[excossack]

Update again.
New router has had the same version of the firmware applied that I have on my old router, so lets see how it goes,
Now running Singtel Software:  5.29.117.3
