There is absolutely no need to increase tx power. Instead improve your antenna, because that will work in both directions (receive branch and transmit branch) while increasing tx power will work in transmit branch only.
It doesn't make sense if you disturb all stations on the channel but receive nothing, because most APs and CLIENTs running 100mW.

I recommend to install Arch Linux:
https://archlinuxarm.org/
Install only services and drivers that you really need.
https://archlinuxarm.org/platforms/armv6...stallation
You'll learn a lot about Linux and if everything finished, you'll have a small, fast and nearly perfect system.
