Well, I may have, at least. Definitely on accident.

The router is a Netgear WNDR3400 V2.

The good news, I manged to source a working identical model one for a good price.

The top one is the blown one, the bottom is the working one. I do know of the component next to the powe jack definitely kableweyed, but I'm not sure what to replace it with, and what else to check for.
