Generate a PDF using LaTeX to share WiFi configuration as a QR code and written text. The QR codes are supported by iOS 11 and the Android app Barcode Scanner (also available in F-Droid) by ZXing Team.

Edit wlan-config.tex and change foo and bar to your SSID and password.

\newcommand{\ssid}{YOUR SSID}
\newcommand{\password}{YOUR PASSWORD}

Then run make to create a PDF called wlan-sheet.pdf using the provided WLAN configuration. It is also possible to generate QR codes with WEP and no password. But why would you want to use this for a WLAN without a password and why would you want to use WEP?

If you really want to use WEP, change to the following in wlan-config.tex.

\newcommand{\authtype}{WEP}

The second page has a QR code with the URL to the webadmin interface of the router and the login details in text format.

\newcommand{\webadminurl}{YOUR ROUTER URL}
\newcommand{\webadminuser}{YOUR ROUTER USERNAME}
\newcommand{\webadminpass}{YOUR ROUTER PASSWORD}

To change language to Swedish replace

\selectlanguage{english}

with

\selectlanguage{swedish}

or use the same pattern for changing to German, Polish or Czech.
