Q: My Airport Extreme guest network has stopped working.
Recently all the computers and devices on my home network were not working on many websites. The browser (use Chrome) spent a long time "Resolving host" and eventually failed and gave a "DNS error message".
I run the home network on and Airport Extreme and run a Guest Network for tenants. They had the same experience. I have the router from our ISP set to have it's wireless function turned off so there is no signal interference with the Airport extreme. This set up has worked for a long time.
I read a lot of reports online about iPv6 issues and tried the "Link-local only" setting but that didn't make any difference, so I set it back to "Automatically".
I then used a Cat5 cable to plug my MacBook Pro directly into the router and switched of my computer's WiFi. Then everything worked just fine (on my computer) and all websites came up nice and fast. So I figured it was a problem with the Airport Extreme (which is in a 2TB Time Capsule - 2nd gen I believe). So I did the hard reset to factory settings on the Airport Extreme and set up my Network again. This worked. Everything works on the network again.
However, I set up the Guest Network again but it is not working. We can see the Guest Network from all the device but when you click on it the wheel just keeps turning and the prompt for password never comes up. The Guest Network just doesn't respond.
Any suggestions?
Time Capsule, OS X El Capitan (10.11.6)
