I've been with Telstra for months now, and overall they're pretty good, their internet being much faster then Telecom.
The downside is the unreliability of Telstra.
I lose my connection not infrequently, and usually it's only for a few minutes.
A few weeks ago I lost it for several days and eventually called them. The support person told me to change a few settings which worked, but a few days ago the problem came back. I haven't changed any settings.
Long story short, I'm using a Belkin modem-router, and the ADSL and Internet lights are both off.
My connection settings are as follows:
Connection type: PPPoA
Username: <Not writing my Telstra username> (it was, but the guy told me to remove the dsl.)
VPI/VCI: 0/100 (I think the guy may have had me change these, but I can't remember if he did, or what to)
Encapsulation: LLC (It was VC MUX, but I was told to change it to this)
MTU: 1454

According to Windows, there is a problem with my DNS configuration, but I've got it set to Automatic from ISP, as it always has been.

What am I doing wrong? Any help would be greatly appreciated.
Oh, and by the way, I'm sending this from the neighbors unprotected wireless, if you're wondering how I'm on the internet.

Encapsulation should be VC Mux and MTU should be 1500 for PPPoA in NZ, try changing those two settings.

I've tried that, didn't work.
Any other ideas?
Thanks anyway.

Sounds like either a line fault or the adsl modem/router is bung... do you have an old modem you can test with or borrow a friends/relatives?

@NightFox, I suggest giving the help desk another call and make sure they log a ticket for you as it sounds like there may be a fault on the line, provided you've done a full isolation test firstly.

@Ragnor, not all xDSL res connections with TCL are VC-Mux.

Ah yes depends if he's on Telecom wholesale equipment in the cabinet/exchange or on Telstraclear equipment in the exchange.

Are TelstraClear moving existing connections on Telecom wholesale gear on to their equipment in the exchange now?

Can't say sorry, haven't seen any cases where that has happened.

Sorry, haven't been able to internet.
Still not working, so I connected to the neighbors again.
I've contacted Telstra...four times. I had to do a whole bunch of stuff, isolation tests, line tests, nothing worked.
I complained, they've admitted it is some problem with them.
Basically, I stopped working last Friday, but continued to try to dial in to ADSL, but on Monday we had our phone line (which had been down for a month) fixed, and now it's not even trying to dial ADSL. Don't know what the problem is, but only Telstra can fix it.
Thanks all, anyway.
Must say, this is a good forum. I just joined to ask this question, but I think I'll keep this account. When I get my internet back, that is.
Thanks again.

Ragnor: Encapsulation should be VC Mux and MTU should be 1500 for PPPoA in NZ, try changing those two settings.

With the new network the OP is on the encapsulation will work on either VC Mux or LLC.

It's a known issue at the moment, the fix is to change the encapsulation from one to another. When changing from VC Mux to LLC it should work, but it's sometimes only a temporary fix and it will need to be changed back the next time the modem acquires a DSL Sync, at which point it's *supposed* to work as normal. (although who knows, it might happen again, I don't know)

There's a fix coming next week which is supposed to fix this problem.

It's something to do with the profile getting locked if too many resyncs occur I think, with VC Mux it gets locked after 5 (quick) resyncs and with LLC it's 20.

What exchange are you using? I got a similar problem here with my parents connection where every few hours the IP address renews which results in cutting the net off for 2-3 mins

With the root cause being the DSL dropping out.
Either due to faulty CPE's or firmware issues and in some cases, old phone lines.

The cost of trying to provide faster connections over older lines, is that they are less stable and either drop out or don't work at all.

Did TCL change you to their new network?

I had the same problem as you did and tried to work this out with their tech staff for over a week, I ultimately bought a new modem because they kept saying it was my modem. So I bought a new modem which worked fine. I should say that my old modem now works as well now after trying it recently (that's another story)

Things I had done which I don't know whether they contributed to fixing the issue or not:-
- connection type - LLC (they told from the outset the default should be VC-Mux)
- manually changed ??setting to ADSL2+
- changed the phone cable from modem (new one)
- changed the DSL filter if you use it with a Telephone

I still think the issue is at TCL end given my old modem still works as well, so wasted time and money for me.
Hope your problem gets sorted but i wonder how many others have had this issue since the change over to their new network.
