So 2 months ago a cabinet went live approx 20m from me, now this is sweet because prior to this I could not sync over 5mbit. Now I would expect sync than my current 11MBit max considering distance from cabinet. My line attenuation is 8 and SNR margin never goes over 15.

Now my old router was very unstable (Linksys WAG320N) so I got a new Netcomm (the one everyone recommends) but my connection is still very unstable and constantly disconnects. I rang telecom and asked to put onto a lower power profile because of the length to the cabinet, this did SFA. I have commercial quality cable run by a mate from chorus directly from demarc to one jackpoint with a splitter so I doubt it is my internal wiring but I am not ruling this out. I have updated the firmware on the router also but I am out of ideas =/

Internal Cabling is only about 3 years old also.

Logged a job with advanced broadband in Auckland to check for PPP Authentication errors, but the guy named Leo(good guy) assured me there was nothing.

help????

Sorry, I can't help - but I would recommend using a more descriptive subject line in future as you are more likely to draw the attention of those who might be able to help (a lot of people ignore posts with generic subject lines)

Good luck.

Are you sure you are even connected to this cabinet?

"my connection is still very unstable and constantly disconnects"

What part of your connection. Is your DSL line actually dropping? Just the PPP session with your ISP? Just it just "stop working" even though DSL Sync and PPP still appear to be up?

"constantly disconnects" is a too broad statement to provide any insight.

PPP Authentication errors would only appear if you were typing your ISP username/password in wrong. What you want them to look for is your modem requesting disconnection (unlikely, but possible if it's overheating and rebooting) or seeing if there's a disconnect on their end due to loss-of-keepalives or similar.

I'm not sure if it's the DSL line dropping but it happens every 15-20mins and I can tell this by my IRC logs. I'm not sure it's the router as I've tried no less than 5 and they all do the same thing, Draytek, Dynalink, Linksys and Netcomm.

On the odd occasion MSN will also disconnect but normally it's just IRC. I have set my laptop up on the same IRC server to test if it's the PC's NIC or cable but the laptop does it on wireless aswell.

The guy from Telecom was saying that he couldn't see any DC's at his end. So is it a possible faulty splitter at my end?

To the OP, learn to use a more descriptive or concise subject heading other than "Help" then you may attract attention to your question.

Woah Nelly! Let's not go blaming the splitter just yet. One thing at a time.

So, you get IRC disconnects. Is this happening on multiple IRC Networks?

If you setup a ping to ring the whole time (ping -t ) and see if you see ping's drop when you loose the session. I'd actually run 5-6 pings, all to different places, and monitor to see what's happening.

If all your ping's die at the same thing, then yes, I'd start looking at your DSL connection. If none (or only some) of your pings drop, then you need to look elsewhere for the problem.

Make sense?

Sorry I sort of added the problems of low sync rate for my attentuation and the DC's together :p

Which I can understand. But baby steps!

So, as I posted, please run some pings tests. As soon as you notice your IRC session drop, go back and look at your pings. Did you lose packets? Did you not lose packets?

That'll tell us the next steps.
