Something seems bad here...

We do know:

1. If we bypass the converter, everything "works" (we accidentally did that before adding in the converter). This tells me the extra plug we bought (same size as the one that came with it) fits and works.

2. If we plug in the power cable that CAME with the D-Link, everything works fine (even after the fact).

3. With the converter in-between, voltages look fine but we're pulling almost no current.

Does this sound fair to say the converter is possibly bad?

That does sound suspect, I remember when we wired ours up I probed it with the multimeter before connecting the radio to confirm polarity and it was reading around the expected 5V under no load. Some SMPS don't work well without load, but if you're connecting it to the router and not getting anywhere, that's weird.

Are you sure your router is good? It seems strange it wouldn't try to pull more current. If the problem was in the converter not delivering more current the voltage should take a dive.
