I am not able to connect to any wifi network. I see dozens of hotspots, but I can't connect to anyone; I can see if they're open orencrypted, and with advanced configurator I can even see the active channel, the frequency... but I can't connect!I tried at least 5 different firmwares with no luck.I heard about some changes to perform to a .DAT file in etc/wireless, but it's not clear at all WHICH changes to do!Any help?
