I have a couple of hobbies that lead to various groups of people gathering at my house on a regular basis. Our groups have had many people come and go over the years, some people only come for 2-3 weeks.The problem I've always had is ensuring that with a lot of people using my wifi on and off over the years I want to make sure I update the network keys regularly. I enable and disable the guest network before and after each session. Until now I have been changing my guest wifi network keys on a weekly basis and re-printing the QR codes (2.4GHz and 5GHz) each week. The printed codes I can then pin on my wall and people can scan and join as they walk in the door.I am getting sick of printing out QR codes and using oodles of paper though.So I thought, what if I update QR codes each week, save them digitally and then dump them into a public folder. I could have a single static link that would display the network QR. I could then single print the website URL QR and have that permanently on the wall. They walk in the door and scan the same QR code but it displays a new image each week.The problem is, the person can scan the QR code off the wall, be directed to a QR image ... and then what? They can't scan it because it's on their phone. How do I make it easy for them to join my guest network?
