   Ummm ... an 'extender' is a bit different from
   an 'access point' (and cheaper). The extender
   binds to the access point/router. Connected
   devices may, as needed, connect to the main
   point or the address of the extender and still
   get net access. Wired equiv is more like a
   hub/switch.

   I do have experience - like last week - with
   extenders. Just got in a cheap spare, had to
   set it up (CAN be slightly confusing but not
   bad at all). My better extender doubles
   the range of my good wifi connection, to
   some out-buildings with some IP cams (and
   soon a home-built "weather" thing (Pi3 based,
   have a couple of spares & some 1-wire sensors)).

   Anyway, judging by the problem you claimed, your
   easy fix is an extender. Use the main point for
   cams/devices at point-blank range and put the
   extender across the bay, best higher up. Use
   whichever is more reliable for the particular
   device in the building.
