Where are you located? Your log says you are using the EU regulatory
domain; however, that is no longer valid. You should add a line like
options cfg80211 ieee80211_regdom=XX
to /etc/modprobe.conf.local. From your name, I would guess the XX
should be DE.
It is likely that the 20 dBm is set by mac80211 as the maximum allowed
by your local regulations. That value is in fact correct for most
locations in the EU.
My rtl8187b runs at a full 54 Mbs and operates at at least 15 m from
my AP. I don't run AP firmware that lets me see the signal strength
from the STA.
