"A: Times change. And yet, the more things change, the more they
stay the same. To put it another way, the answer is
"yes—maybe no." In earlier beta versions of DD-WRT V24,
wireless repeater mode worked only in non-bridged mode; therefore,
clients connected through the wireless bridge could not share the
same subnet as the primary router. With the release of V24 final,
it has been reported by users that bridged repeater mode does work.
Yay."
