Hi there, mine was the older b/g version. I'm unsure if this is the same as bridge mode. The pre-801n utility doesn't name it as "extend network range" if I'm not mistaken. But I really doesn't spend much time configuring it. As my main white UFO base station are strong enough to cover my whole house even if it's at 25% power.
Oh yeah, PoE can't be use 40+V is too much. But I can still use the non-powered ethernet and wire my 5V in over the unuse pins. Then I can have a neater hack. But will only try so if I get another unit of power-failed Express.
