the problem is: all my comm is in the upper corner of the house, and the ducting/walls obstructs the signal to the lower corner of the house (in fact, no signal at all). so i dug up an old actiontec router in the hopes i can 'chain' it w/ ethernet from my main n-router & use it as an alternate access point for the basement. i have a 25' ethernet line i can fish through the basement's upper joists. can it be done? i'm not too encouraged, as it *appears* the dsl router gets fed from a line in, and not ethernet, which could possibly be used for broadcast only.
