My router is centered at the end of my basement and covers the entire
2 story house, including the garage (far end) front porch, and rear
deck. Not a big house though.

My router is located under my desk in my home office. I couldn't get a
"reliable" signal in the living room, just 20 feet away. Of course, there
are three walls, a heater, steel bathtub, plumbing, and wiring in between
the two rooms.

Adding the access point in my attic solved all of my WiFi issues. I now get
a strong signal anywhere in the house. Ironically, the signal from the
access point is a bit weak in the office, but my normal router takes over
in that case.
