Robert, you were right, but, now that I used a switch the way you proposed, I got this strange behavior: As soon as the WRT gets power, I get a couple of ping replies, but after that nothing, just as before (except maybe that arp showed the router's MAC address). Would that be an indication of a hardware problem?

In the best case, not always, I get only a few ping replies, as I said above. > > Unless there is something you really need from the existing > configuration, I would just > go ahead and TFTP a fresh copy of backfire or trunk That is my intention.
