OK, now that you have told me that bit about pointing it in different directions I will say something about polarization. The wave front is polarized, and depending on how the AP was setup it can be horizontal or vertical, and of course travel through walls and being reflected will twist the polarization, so not only do you want the antenna to face towards the source you may want to rotate it to see if you get more signal. Off polarization antennas can cost a lot of dB. When doing links that is a old trick to run two antennas in closer proximity, run one horizontal and the other vertical and you will get about 30 dB of isolation.
