I've suggested this to every AirBnB I have stayed in. Sadly I am up to about 75-100 of them and have come across this a grand total of zero times.

It might have to be setup by an Airbnb host but the past few places I've stayed at had the ability to press a button inside the Airbnb app to automatically connect to their WiFi. Definitely saves some of the less tech-savvy hosts from having to figure out how to create a WiFi QR Code and print it out

I've started deploying purpose-specific APs that I simply plug and unplug as I see fit.

So, for instance, if I want to use tor, I have an actual tor ap that is normally powered off. I plug in the PoE connection and a bit later I have an SSID that is Tor only.

I also have a "guest users" AP that has no password at all. Plug it in when needed. Unplug when people leave. Shrug.

I use the Ubiquiti frisbee APs that are PoE. Sometimes I insert a "slug"[1] between the switch and the AP which strictly enforces their purpose - like hard locking them to a VPN.

It's remarkable how something as trivial as typing 26 characters is onerous on our glassy slabs, but image processing to resolve a high-resolution two-dimensional barcode in a video stream is easy.

Computers are fast and they usually don't complain when you make them do work.

On the contrary, I've known some that get quite loud.

What a weird design. Alphanumeric QR code encoding includes [0-9A-Z $%*+-./:]. So many characters to choose from and they decided to choose ';' ruining the possibility of using compact alphanumeric encoding. Perfectionist inside me is angry!

Especially weird considering SSIDs are allowed to have : and ; in their name. Should have gone with something like $

I've done something similar, but didn't like the static passwords. My guest wifi password is the current date, in YYYY-MM-DD format, it's been a great way to keep my guests (mildly) satisfied. The format changes on occasion

So guests who stay overnight have to enter a new password after your script runs at 00:01?

I'm in an Airbnb and the access point has the same name for 5ghz and 2.4ghz. Apple doesn't let you manually switch. The only way I've found to switch when one is not working is to toggle the wifi on/off fifty times. I think there must be some sort of crazy interference going on because I can literally be sitting right next to the router and 5ghz has about 5k of bandwidth available.

In my experience, Apple devices tend to connect to whichever seems stronger at the time of connection, and then only ever change to a different AP when the connection gets extremely weak. Or randomly, just to mess with you.

That's unfortunate. I've tried to reset the router but it still loads the old settings. Next time I go back to the US I'm going to bring back mesh routers.

This 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…

You can always put the password on the same piece of paper as the QR code. So if they don't know how to scan the code, they can type it in, no need for your to spell it either.
