I have this question and haven't found an answer in other questions.
Say there's a place in my house where I currently get none or a very poor signal. If I somehow managed to increase the strength of it (changing the router, using other firmware, etc.), would my notebook or phone be able to use that connection?
I might be very wrong, but I am thinking it would solve just half of the problem, since any device using that connection would have to "speak back" to the access point, and since the device signal strength hasn't been improved, it wouldn't be able to do it due to the obstacles that previously made it get a low signal.
