On: Guest WiFi using a QR code

[megraf]

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

Is this automated or do you need to change every time Guests are expected?

This is automated, with a shell script and DDWRT

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