Netgear access point on 2nd floor of townhouse in home office - lots of equipment and crap in that room. Laptop with
Netgear wireless card.
I am using the laptop right now one floor down in the living room. I can game on this signal.
Laptop works on patio one floor up (on roof). Great signal too.
Laptop also works in garage 2 floors down while I'm sitting in my car (not a convertible
). Mediocre to poor signal.
Laptop does not work out front door 1 floor down. It works across the street out back just barely, in line of sight of the window of the home office. However, as soon as I lose line of sight, I lose the signal. (Lots of brick buildings around.)
I betcha if I had the access point outside though with the laptop outside, with nothing around and no walls, I'd get several hundred feet.
So the real world indoor range is much less than any of the companies claim. Even 30% is optimistic, and my setup is considered one of the more robust ones.
