   that's not always possible and won't work in a large house (or even   
   medium size house).

   trying to get coverage with multiple access points is the very problem   
   mesh solves.

   power over ethernet may be convenient but it doesn't affect wifi   
   propagation.

   either you're incredibly lucky or you're greatly exaggerating.

   your bandwidth requirements must be rather low if you're satisfied with   
   a signal that goes through two floors.

   that's an overgeneralization and depends on many factors. in general,   
   it won't be that high.

   which is what most of them do, sometimes more than just two and in some   
   cases, there's a wired backhaul.

   not necessarily.

   poe isn't the topic.
