Android TV screen cast not working after FW update

Routers
1

Hello,

I have updated the firmware on my Slate AX (GL-AXT1800) from v4.6.11 to 4.8.2. After the upgrade, screen casting form my cell phone to my Android TV is no longer working. It was working right before the upgrade so this must be related to the router firmware. Both devices are on the same wifi network. Perhaps there is a new setting that must be enabled to that two wifi devices can talk to each other. Please help debug and provide fix.

Thank you.

I can add that I am using the router in wifi repeater mode connecting to a hotel network.

Also, AP isolation is turned off in Network → LAN.

ok, I now found the mistake. IGMP snooping was turned off during the upgrade. After turning it on, the screen casting is working again.

Perhaps someone will find this useful in the future.
