This is doubtful. Routers normally don't allow administrative access through the wireless interface.

Um yes they do ...
Been there done that
By default linksys wireless routers use "admin" with no password.
I disabled one of my neighbours router for a few days just to see if they could figure out what the problem was...
after 4-5 days I decided to let them off the hook and re-opened their router to the world.
They never did get it secured...
