Odd networking problem

[Peter King]

Here's one for the experts.

I have a netbook running OS X. The ethernet connection to my router is reported
to be good, but I can't ping the router, much less connect to the net. Nor can I
see the netbook from other computers on the LAN.

Normally, I'd think this was a DNS problem. As far as I can tell (I don't know 
much about OS X), it isn't; the nameservers work for all the other computers on
the network, so they should be okay.

Routing? Well, according to netstat -nr, the default route does have the IP address
of the router. I tried adding the default route manually anyway, just to see, but
no difference.

At this point I'd suspect the cables or the hardware. The cables work fine with
other computers, though. To check the hardware on the netbook I put sysrescuecd
on a USB stick and booted from that. The ethernet connection runs perfectly with
no fuss or feathers at all.

Now I'm at that place known to us all: Wit's End. Any suggestions for what to try
next? (Other than "install Linux instead of OS X" -- it's my daughter's computer,
not mine, otherwise I would have done that long ago.)
