I made some small tests adding directors to my antenna, as you know them from old yagi antennas for TV on the roof of a house (building them was my hobby over 10 years ago).
I also changed the reflector-layout to get more bundled waves.

I got maybe 2% higer values, but also the dropouts were worse.

In a room, you have many interferences, so yagi-antennas are no good solution. They require very "clean" waves for good results.
They are only good, if you have direct sight to the sender (for long distances).
If the sender is in another room, simple reflectors as above are the better choice.

I tried
ifconfig rausb0 up rate 100000
But it still uses higher rates.

No, try:

Iwconfig rausb0 rate 1mb

This works with most drivers, though some don't support rate changing. It works with my rt2570.

I believe the correct syntax for the "rate" parameter with iwconfig is "k" - kilobits/sec, "M" megabits/sec, or "G" gigabits/sec.
So -

iwconfig rausb0 rate 1M

I have found that modern wifi adaptors can sometimes work more reliably by forcing them back to the old 11Mbs "B" mode. In this case -

iwconfig rausb0 rate 11M
