Airplay & Screen mirroring

[khnguyen98]

Hi All,

Sorry if this question is duplicated and a long post 😊. I have a question regarding the Airplay and screen mirroring issue from my iPhone with a smart TV (LG). My phone can see the LG when I'm trying to mirror the screen. However, it came with error message and can't mirror. I'm trying another iPhone on the same network, and failed. When I use a Windows laptop to do wireless connect display, it worked just fine. So I narrowed down just the Boujour or something with my phone/TV. I then connect both of them to another Wi-Fi lab without Meraki in the environment, I can mirror without any issues. What am I missing here with Meraki setup? Here's my setup: I  have a MR 36 and MX68 on a flat network with no VLANs. I set MX68 on the "Passthrough or VPN concentrator" and all the IP addresses coming from ISP gateway. For the MR36, it's on the "Bridge mode".

AirPlay uses Bonjour (mDNS) to discover devices on the same network.

Also take a look at this.

Check the Bonjour Forwarding.

I tend to avoid configuring Bonjour forwarding on the AP, and instead configure it only on the MX. I've had some difficulties with Bonjour on the MR.

I believe the MR's have issues when your _service_ is not listed under their preprogrammed services.  The MX will forward others if you set it to all services.

You shouldn't need bonjour forwarding if the devices are on the same L2 network.

Have you got any firewall settings on the SSID blocking local connections or block local LAN?

It's likely the windows laptop works because it's using Miracast which is a "Wi-Fi Direct" technology and doesn't require both devices on the same network.

@Brash looks like this policy in the MR (I believe it's there already because I can't recall I set it) probably causing my issues: 

I will try to remove or allow it later today to test it out. Thanks.

[alemabrahao]

Yes, that's probably the problem, set it to allowed.

[khnguyen98]

So I've changed that Deny policy to Allow and it still didn't work either. I'm still stuck at this point.

I suggest you perform a packet capture.  

Otherwise I suggest you open a support case.

I've changed the Policy mentioned above in MR. I still have the issues. I'm stuck at this point.
