I'm having this problem with my chromecast: "We could not communicate with your Chromecast. It's possible that your Chromecast and device are connected to networks that are unable to talk to one another. This may require a small change to your Wi-Fi router settings. Learn more here." When I do in fact click on "here" it takes me to this support page that talk about AP Isolation, and how I should disable it. I have a Netgear WPN824v3. I have searched through ALL the settings, and I have found nothing on AP/Client Isolation. In fact, I've even pinged the devices from the CMD and I the pings are successful, so my devices can communicate with one another. So what is the problem!? I got it to work yesterday, but then within the hour this happened, and now I can't get it to work. Help!
