I print out a sheet with some text (including the network SSID and password) and a QR code to connect to the guest wifi using libre office writer. It has a built in qr code generator. The QR code text for a wifi password is here: https://en.m.wikipedia.org/wiki/QR_code#Joining_a_Wi%E2%80%91Fi_network https://en.m.wikipedia.org/wiki/QR_code#Joining_a_Wi%E2%80%9.... No need for any special third party tools.

There's also the LaTeX qrcode package, bundled with distributions like TeX Live. Minimal working example reduced from my own template: \newcommand*{\SSID}[0]{NETWORK} \newcommand*{\PASS}[0]{PASSWORD} \documentclass{letter} \usepackage{qrcode} \begin{document} \begin{center} \LARGE{``\SSID'' WiFi QR code} \qrcode[height=5cm]{WIFI:S:\SSID;T:WPA;P:\PASS;H:false;} \end{center} \end{document}
