Most routers offer much the same output power. This is limited by
legislation. The actual limit is the radiated power, so for the transmitter
a high gain antenna will be no help.
However the receiver will benefit from a high gain antenna - effectively
this means that a given signal at the antenna will arrive at the receiver
input increased by the gain factor of the antenna. Antennae generally
achieve their gain by being directional; this gives the advantage that they
can minimise on-channel interference from other transmitters not in the same
general directin.
It also helps if the receiver is more sensitive. So the wireless devices
that give better performance probably have a more sensitive receiver.
Therefore both the wireless router and the adapter in the laptop will affect
performance.
As others have suggested, a wireless repeater placed at an intermediate
location might improve performance and allow you more flexibility in
placement of the laptop.
