We are dealing with a two-way radio here. Radios either "push" a signal, or
receive a signal that has been pushed by another radio. They do not "pull" a
signal any more than a piston in an engine "sucks" in air on the intake
stroke. The atmosphere "pushes" in to fill the space created by the decending
piston. I think the only ways to increase the signal strength are to increase
the transmitting power, decrease the distance between radios, remove
obstacles between the radios, reduce RF interference, and use directional
antennas.
I am sure the FCC regulates transmitting power, so that ain't gonna happen.
Decreasing the distance and removing obstacles between your laptop and the
wireless router may or may not be practical. Reducing interference might be
possible, talk to your IT people. This leaves the directional antenna.
On a side note, I have a USB wireless adapter that frequently dropped the
connection on large downloads. I attributed this to heat, or buggy driver, or
poor design, or whatever. Signal strength was excellent- when it worked. A
different model from the same maker didn't suffer that problem. Not because
the signal strength was better, but because the hardware and driver were
different.
Also, N doesn't increase the transmitting power, it increases the data
transmission rate because the frequency is different, but the FCC still
regulates the power. You might be able to find a card that is less prone to
dropping out, lack of signal strength is probably not the issue.
