Airplay isn't showing up on MacBook Air using WiFi

Just bought Apple TV for conference room in our office. Had it hooked up to WiFi, airplay wasn't coming up. Hooked it up to ethernet and iOS devices got Airplay.

The only way to get the MacAir to see it is to change the office system from WiFi to direct. It's a Cisco router. WiFi always works well until we hooked up the Apple TV.


Our IT guy is looking into Multi casting because he found others having trouble.


Anyone have any thoughts or suggestions?


Thanks in advance!

About AirPlay and Airplay Mirroring


AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer). For non-qualifying Macs you can try using Air Parrot.

Using AirPlay


Thanks to the $15 Beamer, AirPlay streaming is still possible on Macs that do not support Airplay and mirroring.

Other solutions are the Air Parrot, StreamToMe, and AirServer.

If the ATV and your MBA are both on WiFi, can you see the Apple TV? If one device is on Ethernet and the other on WiFi, can you see your AirPlay icon in menu bar?


From the ATV UI, find out the IP address of the ATV and run a Wireshark capture on local LAN segments for the IP of the MBA and IP of the ATV?


iStumbler has a Bonjour browser (or any other Bonjour browser for MAC will also work - http://www.tildesoft.com).

Few extra details:


Both networks on the same (wired and wireless) 10.10.20.x/23

We can ping the ATV and MBA and Windows device from wireless and wired.

The Cisco wireless controller is a 2504

Wireless Access point: AIR-CAP2602I-A-K9

Entire network is using a single Vlan

All connectivity on the wireless side (internally) is not being filtered / access controlled

Multicast was turned off (since turned it on)

IGMP snooping was off (Since turned on)

mDNS is enable and working. It shows the ATV device in the mDNS list.
Apple-TV.local.

Mac address

Ip address

Vlan ID

Type

TTL (in seconds)

Time left (in seconds)



This morning this is what worked using windows machine with airparrot:


Connect with the wired network works every time (wireless ATV), (Wired laptop airparrot): Disconnect wired LAN, connect wireless LAN (Airparrot works until airparrot is closed)


Mac devices: ATV (wireless)

iPhone, iPad (wireless): works every time

MBA (wirless): Works none of the time. The square airplay(display?) icon now shows up but says no device detected.


If the ports were blocked in the wireless controller why would it work sometimes and not others?

This suggests that the MBA may have an issue. If iPhone/iPad works, then there is a possible firewall on the MBA which is causing problems. Can I, again, suggest downloading Wireshark on the MBA and capturing packets on the wire. If you have the ability to capture on the hop before the wireless MBA towards the MBA, it would help as well. I would also suggest comparing wired vs wireless packets on the MBA when it can and cannot see the ATV.
