You can try "arp -a" from terminal to see if there's lower level awareness of the router, in which case you should see the router's MAC address listed as a neighbor, in which case, you would at least know that it's a higher layer where the problem resides.<div>

Well, traceroute works by measuring the length of time between "ping" hops,<br>
but I can't even ping the router -- so traceroute gives nothing, in either<br>
direction. The router doesn't recognize the netbook as connected under OS X,<br>
even though it registers the presence of a "live" ethernet connection at the<br>
correct speed. I guess that's all lower down in the seven layers.<br>
<br>
Tried reinstalling the drivers, too, without joy.<br>
<br>
Browsing the networking configuration plist, I *did* find that the router's<br>
mac address associated with the ethernet port isn't correct. That might make<br>
a difference, if I could figure out how to change it (short of blind-typing<br>
over the configuration file which I'm hesitant to do without having a better<br>
idea of what's going on in the internals).<br>
