[maemo-developers] [maemo-developers] poor WLAN performance

Hi, as far as I know you can choose 10mW or 100mW when setting up and
storing a wireless connection (in advanced preferences). What applies
for a new connection (not a stored one)?

Maybe it's using 10mW instead of 100mW. Could it be a software bug
then, instead of hardware? I'm just guessing...
