generally it is not the signalstrength which let you connect at higher speeds,
it is the noise level. So you can have a low signal without noise and you may
connect at high speed and on the other hand you may have a strong signal and
high noise and the speed is 1Mb or do not connect/associate at all

tha card default in autoselect is probably 11b so it do not connect at 11g
until you configure it to
ifconfig mode 11g media OFDM/54mbps
should do the job,, tha card still connect at lower speed depending on what it
can with the selected AP
in order to not jumping around you can try setting bssid _MAC_desired_AP_
so long as your card is in monitor mode you may not connect nor get traffic at
all
