PPPoe Problems

I have an ibook and an old slot load imac, both running System 10.2. The two machines are on a LAN, which has an ADSL modem connected to it which connects using PPPoE. I don't have an airport or a router, but that's fine, and just means I can only connect one machine at a time.

Everything was dandy until last week, when the ibook suddenly decided not to connect any more. The imac still connects fine, but the ibook just gives the "PPPoe server not found" message after a few minutes. My setting are all fine. The ethernet port seems fine as well, since the ibook can still see the other computer and communicate with it as normal. It can even ping the modem, so the connection to the modem is fine.

I've tried absolutely everything I can possibly think of. I've moved all the cables to test it's not a connection problem. I've tried connecting directly from the ibook to the modem. I've rebooted in System 9 and tried connecting with Enternet and can't connect that way either. I've even erased the ibook's hard disk and rebuilt both systems from scratch as a last resort. On the basis of that I convinced myself it must be a hardware problem, counter-intuitive as that is, but since then I've come across a collection of users who have had exactly the same problem and though none of them seem to have found a solution I can replicate, it seems there are suggestions in some quarters that there is a problem with PPPoE in Systems 10.1 and 10.2 on certain machines.

Could this be a problem with the ethernet software settings? Would resetting the ethernet to the factory settings through the Terminal be a possible solution? I don't know how this could be done but if anyone thinks it might work and does, please let me know. Alternatively, could I reset the firmware to achieve a similar result? These might sound like stupid ideas but I'm really at my wit's end about hat's wrong (Apple Australia have been quite stunningly useless).

Alternatively, has someone else had a similar problem and fixed it? Any suggestions will be gratefully received.
 
Have you tried connecting from an other machine or from OS9 using a PPPoE client? If that doesn't work, it could actually be your ISP. And if your ISP supplied your modem, it's their responsibility to replace it (unless you've played inside it with a screwdriver or something :p )
 
I have tried from another machine on the same network (the one I'm on now, in fact) and it works fine.

I've also tried connecting from OS 9 on the affected machine and I have the same problem. This would suggest hardware to me, but since all other ethernet stuff on the machine works fine I can't see what could be wrong with the hardware. Working from the other direction I've gone so far as to wipe the hard drive and reinstall from scratch withut affecting the problem, which is why I'm guessing there's something wrong somewhere between the level of hardware and system (which is way beyond my capabilities to fix).

As for the modem/ISP suggestion, my feeling is that the problem is definitely at my end. The machine worked one day and then didn't the next, and anyway, my ISP have been fantastically helpful, and have got me to do things like ping the modem and open the modem in Explorer etc to check everything is okay, but they're as baffled as I am.

Any more ideas? I'm more than a week in and I'm still waiting for Apple's tech support to get back to me. They won't even give me an ETA, which is maddening.
