Hello! Is it possible to downgrade the firmware of an airport extreme base station? I want to connect a computer to my home network but its wireless options (usb adaptor) only allow 40/128 bits hex and ascii encoded passwords. My airport extreme base station is running the latest firmware update, 5.6 was it I guess, were I can only create WPA or WEB passwords. So, while I find my network with the mentioned machine I can not connect because there is no password option the computer and the base station share. I think there are firmware "downgraders" for such things on the apple homepage, but after some serious searching I was not able to find anything. Of course I could reset the whole base station but I don't want to rebuild my network with all the settings for this. Thanks in advance for any kind of help!
