"ShinyTortoise78, no spaces, capitalization on the first letter of each word. Seventy Eight is the numbers 7 then 8, not spelt out as a word" "Uhh English is my 3rd language and I don't know how to spell tortus. is there a QR code I can scan?"
The optimal solution is thus: "What's your wifi password?" "It's written right there on the fridge"
Is that an O or a 0?

vs Whats's your Wifi password? A: I don't know it's written on the back of the modem.
Aha... apparently you have met ALL of my relatives who have absolutely no understanding that they could login to the device and change the password to something better.
Some of the rental hardware no longer allow users to login as admin. Some of the ones that do the ISP landlords make a lot claims that leases/monthly fees go up if they think to try. There's a growing disparity between modem/router hardware owners and "this lease seemed like the best deal from the cable/phone company" average users.

#145I 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%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}

Both my Pixel phone and Samsung tablet pick up URLs and SSIDs from the QR code using the stock camera app.
My last phone, LG Nexus 5X, couldn't do this. My current phone, Unihertz Jelly 2, also can't do this. Guess I have to buy the "premium" brand Androids for this feature.
You're not missing out. My moto g power (2020) can sometimes manage the feature, but only sometimes. Sometimes it just won't scan with the regular camera and you've got to open a dedicated qr scanner... So you're really better off starting with the dedicated qr scanner... except I have a button on the home screen for the camera and have to dig for the dedicated app.

#148This is super cool and would be awesome for situations where your guests are familiar with QR codes. But from my experience the process would go something like this: Visitor: What's your wifi password? Me: No password needed! We have a cool QR code you can scan that will auto-join you! Visitor: Oh cool, how do I use a QR code? Do I need an app? Me: Nope, just point your camera at it. Visitor: Like .. .take a picture…
I agree with scenario one but also think you went too simplistic on the second scenario. Even with a simple wifi password like you suggested, you still need to specify the uppercase letters and plenty of people might have trouble spelling tortoise correctly on the first try. Nevermind the fact that my friends group tends to be about 50% passwords of the type you used and the other 50% of them use a randomly generated…

I keep teaching my family members to fish, and they keep asking me for fish.
Re: Guest WiFi using a QR code
#149A QR code by itself is completely unreadable to a human. Can't this have the SSID / password too? All too often you see what should be simple textual data wrapped in this obtuse form which only specific machines can read. Text and a QR code can be read by everyone. See: https://twitter.com/adambowie/status/1521078234057695233 > for context
Agreed. Where I used to work, IT started replacing the guest wifi (password changes monthly) with QR code instead of printing out the password on a piece of paper. It's really cumbersome when I want to join on my laptop.

What if instead of QR, it was a special human-readable text format that was optimized for image recognition? Like a special font or something.
I suspect that the cameras on low-end phones would struggle with OCR text in suboptimal conditions (low-light or damaged text). QR codes have redundancy, which makes them resilient in a variety of conditions that plaintext isn't. Also, you can 'hide' ugly tracking urls in QR codes (e.g. a short-link that lets you count number of scans or update the redirect location).
