Why have a non-'guest' network? Force anything secure over a proper VPN E.G. wireguard.

Hadn't really considered that. A bit inconvenient, I don't know that I'd want to VPN inside my own network just to access my servers.

Surely this is desirable while away from home too?

Not sure I could enforce QoS priority on the wireguard traffic. Easier with a non-guest SSID. Is there a huge performance benefit if there's just one SSID running in my airspace? Also, for the OP, sounds like it's time to put the kids on the guest network.

You can QoS tag by whitelisted mac addresses if it's just priority to known devices generally. At best your router may be able to slightly shape devices on the network (strategically dropped packets). QoS over the air doesn't really work as there's zero control of any devices tying up RF spectrum, and zero ability to defend against DoS attacks (E.G. neighbor trying to stream 4K over wifi).

Bit of a self-plug I know, but this reminds me of something I had made a while back ( https://github.com/kmanc/wifi_qr ). Nice work! Always fun to see others' take on neat projects

It took me a second to understand what this does, but wow what a neat project! Thanks for sharing, this sort of overkill is my favorite kind~ Cheers @koins!

Lol thanks! I strive to bring more nerd-value than real-value :P

Maybe! The problem I was trying to solve was that a 30 character password randomly generated is a pain to type out by hand haha. That said I think having the text would be a step in the right direction

Bootstrap it with a shorter password: 1. Have the display show a 5-digit PIN (TOTP or something that changes every minute or few) 2. Let anyone connect to your network, if they go to a browser window it will show the capture portal 3. Enter the 5-digit PIN and press "enter" and the page will show the 30-digit password so the user can copy+paste 4. User pastes password into WiFi screen and logs in Make sure to rate-li…

Yeah that's certainly another solution. I haven't played around much with the captive portal capabilities of my networking gear but maybe I should

The optimal solution is thus: "What's your wifi password?" "It's written right there on the fridge"

"oh, I have to get up from my table, carry my laptop over to your fridge and attempt to type in the password without dropping anything?" (I have a horrible short term memory and struggle with short phrases)

If someone wasn't smart enough to realize they could take the piece of paper off the fridge, I'm not sure they'd be able to operate a computer

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…

So support both? Just post a paper on the wall with the name/password spelled out, and also a QR code. If people know how to scan then it's fast, if not then they can read+type the old way.

Wouldn’t it be easier/maybe more practical to print the password to the e-ink screen as well? (QR code error correction is usually enough to let you just knock out part of it and put the text right there.)

Just use diceware; 3-4 randomly selected words is enough entropy but still easy to type.

I print wifi QR codes on wood signs and on cork coasters for Airbnb/VRBO hosts. It's a good little side business. https://www.etsy.com/shop/ligninandlight?section_id=28828952

I 3D printed a QR code puck for my house wi-fi. It's an easy demonstration of at-home fabrication that elicits some conversation, without having to hand over a password.

> without having to hand over a password.

I mean, you're still giving them the password, just in machine readable format.

"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?"

Just make your WiFi password simpler
