quite a few networks to choose from, but.. those with a ! on the rssi
column aren't considered because the signal is too low and all others
are encrypted not open. Do you by any chance have some scan results
from Linux or something available to compare too? if there is a
significant diff in the signal quality I might have to look into the
antenna setup.
