Use QR Code to gain Wifi Access
To get Wifi access by use of common QR Code scanners, you have to QR encode the string WIFI:S:MySSID;T:WPA2;P:MyPassword;; which can be generated with the open source tool qrencode:
qrencode -t PNG -s 12 -l L -o MyNetwork.png 'WIFI:S:MySSID;T:WPA;P:MyPassword;;'
Apart from replacing MySSID and MyPassword by the right values for your network, you might need to replace WPA by WEP. I was told, a WPA2 might work as well, but WPA seems to be generic for both WPA and WPA2.
For a hidden network, a H:true is expecte as a last value, seperated by another ; and finished by a pair of them. In case of no password (no encryption), just leave the values empty.
