How can isolation be disabled?

I found the setting.  Go to the router admin web page and login as admin.

Select “Advanced” tab.

Go to “Setup” / “Guest Network” page.

Scroll down to “”Wireless Settings (2.4 GHz)-Profile.

Check the box for “Allow guests to see each other and access my local network”.

Scroll down to “”Wireless Settings (5 GHz)-Profile.

Check the box for “Allow guests to see each other and access my local network”

Hit Apply.  Wait for reboot to finish.

Now your main WiFi Network connections and Guest Network connections can all talk to each other.  I needed to do this to allow each Guest connected device to talk to each other, for example an iPad and a Tablo DVR, otherwise they would not see each other and the Tablo would not work on the iPad.

Seems like Netgear wanted, by default for security, Guest Network users to not only be isolated from the main network but also from each other.  My use of the Guest Network needs all guests to see each other.  Ideally there should be a checkbox for all Guest Network clients to access each other and a separate checkbox for the Guest Network clients and main network clients to access each other.
