Why would ONLY my guest wireless network be working?
Beginning suddenly, my main home wifi stopped working. The devices connect easily to the wireless network and show high signal quality, but there is no connectivity to the internet. Everything works fine while wired, and I can access my LOCAL network correctly (Apple TV, Remote, File Sharing, Screen Sharing, etc), but my main network will not allow me to access the internet.
The Airport Utility does not show any problems (Double NAT, etc).
Throughout all this, the Guest Network works as expected as does my wired network.
Using WiFi explorer and inSSIDer, I am showing some other neighbor networks at high signal strength, but not sure if that is THE cause of the issue.
I have several variations on Airport Express, Time Capsule, and Airport Extreme, and this problem is the same across all of them, so I don't believe it's hardware dependent.
Any troubleshooting steps or remedies would be appreciated.
