I have been having some internet troubles at home (ADSL2+ connection in Australia). We get random drop-outs from the authentication connection. It will keep the connection to the DSL service, but we lose authentication and either have to restart the router/modem (its combined, a Belkin one, not sure on model number) or unplug the phone cable, wait about 30 seconds and plug it in again.

I've called the ISP (Telstra) a few times, but they only offer limited support when we dont use their supported hardware. Apparently something had happened on their side, they checked the box again (at least it sounded that simple), and told me it would be fine.

It wasnt.

I've replaced all the filters around the house, but that didnt help either. We do live a little bit away from the exchange (get a sync speed of about 3000/900), so I thought it could be due to line noise but that hasnt helped.

Telstra allow both PPPoE and PPPoA connections (which I'm configuring through my router, dont have software on the PC side). I've been running PPPoA the whole time, would it make any difference changing it to PPPoE?

If not, are there any other theories as to why we would be experiencing these drop-outs? It has been fine for at least 12 months, then suddenly started about 2 months ago.

If its possible, your devices should be able to store the authentication details etc. keys and passwords. I recommend that you read more on your network devices.

Regarding about the PPPoA you might want to have a look at this link text

If your internet connection is waek it might be due to your geographical location problem. Perhaps there is a maintainence issue? However to ensure that your ISP network is the issue here, I also recommend you to throughly scan your computer with Anti viruses as Malwares will often cause signals to be extremely weak.

Hope these information helps.

Hmm, I would say that its not malware or virus related, as it happens to every computer, xbox 360 and iphone in the house all at once. Also, the modems connection light actually goes out. – AkkA Sep 17 '10 at 8:52
