Hi all.

I recently replaced my vodafone issue Huawei modem, hoping it would fix frequent internet dropouts.
I believe I successfully set up the vigor 120, I put it in pppoa to pppoe bridge mode, and let my wl520gu (tomato firmware) router handle authentication. 
The connection is now stable however I am getting much slower speeds than the huawei modem.
2.5 mbps compared with 5mbps.
My question is if there is anything I can to do about it, an incorrect setting maybe etc?

A couple of questions for clarification.

What are the connect rates that the Vodafone Huawei modem gives and the connect rates of the Vigor?

You mention specs of 5 and 2.5. Are these the throughput rates from a speediest site and is this connecting via ethernet or wireless?

Just to confirm that you have set the Vigor up correctly, you shouldn't be able to access the Vigor's web interface when it is set up in passthrough mode as it is transparent when configured correctly.

Can you list the line stats from in each modem when connected, eg: line attenuation, noise margin etc.

The best way to answer all of these questions, and the next one I'll be asking you, is to get the ADSL diagnostic output from the modem.

I've quickly thrown together a guide on how to do this at http://www.draytek.net.nz/draytek/support/diagnostics

Please copy-paste or screenshot this information and reply with it :)

Were you using the tomato router with the huawei? Or have you turned on any QoS on recently on it?

I can access the vigor120 but only when it is plugged directly into the computer.
My throughput speeds i used an online speed test connected through lan. Will be back with line stats.

It looks like you've got an ADSL1 sync (G.dmt) on a Ikanos DSLAM - that seems strange. Are you very far from the cabinet/exchange? If not, I'd definitely suspect wiring.

I'm 3km from the Invercargill kennington cabinet/exchange(as the crow flies). , pretty sure it hasn't been upgraded to adsl2+.

Your attenuation suggests closer to 4km of phone wiring to the exchange, so 5megs wouldn't be reliable as you found but may be different each time due to fluctuations in the noise margin. I reckon the draytek is picking up the best speed that's sustainable to avoid dropouts. Ask your ISP if they can get Chorus to put you onto a long reach profile, might help a bit.

Plan to get the wiring checked very soon. I checked with a mate who is just a bit closer to the same exchange/cabinet than me. He gets 5mbps and it is a stable connection. I'm guessing as suggested the master splitter may also be a good investment.

I rang vodafone tech support and described the issue I was having.
First he thought my modem (vigor120) was slow because it might be set on adsl2, I confirmed that it was
definitely set on g.dmt. Then he went on to say that, the vigor 120 is too 'high tech' for my connection and that he thought changing the modem to a Belkin or cisco-linksys.
Even though the huawei modem was dropping out he still denied wiring was an issue.
Is there such a thing as too high tech for my connection, what do you make of this?

The person you spoke to sounds clueless, thats normal. Just insist you want a wiring check. You will have to foot the bill if no fault is found though, thats how telstra did it for me anyway.
