Chromecast not showing up as a Cast destination on a corporate network

[ZZman]

For some reason after setting up the device via Home, the Chromecast does not show up in Chrome as destination for casting.

This is our public network, so a simple password is all that is required to login. The device I am trying to cast to IS on the same network. Thanks.

Does that network have the client/AP isolation security feature enabled? If so, this will not work as the phone or tablet cannot communicate with the Chromecast. I would also check these settings, which are required for Chromecast to work properly.

Enable: 

• Universal Plug and Play (UPnP)
• Multicast
• Internet Group Management Protocol (IGMP)

Disable:

• AP/client isolation
• Virtual private networks (VPNs) 
• Proxy servers
• Internet Group Management Protocol (IGMP) Proxy
• MAC Address Filtering
