AirPlay over ASUS RT-N56U

Had airplay problem myself after I upgraded to firmware 3.xx regarding the router (same as yours).

Disabled IGMP snooping and then it works.

In router settings:

• Wireless
• Professional
• Disable IGMP snooping for both 2,4GHz and 5GHz
• Apply

Neither davebrook nor andrew132 have discovered a fix. Both of these "fixes" are documented elsewhere, where you can see that they do not end up working. Andrew132 is not located too far from the router. The multicast setting did not fix the problem. It appeared to be fixed, but in reality it was just a coincidence. The fact that you had to turn the wifi on and off shows this to be the case. Furthermore, while I can't tell what either of you did to test, everyone should be aware that the fact that the airplay icon appears in Finder does not mean that that it is working. Often the icon persists after the actual ability to airplay is lost by the router.

The IGMP snooping merely resets the router and that temporarily fixes the problem. In any case, even if these were genuine workarounds, they would still be just that. A fix would not require you to do anything. That's why ASUS should step up here and actually fix the problem. Airplay is a standard, widely used protocol that should be supported by default.

I had the exact same problem. The 3.xxx firmware seems to have trouble with AirPlay. My router fortunately had an older version of the firmware (1.0.1.7f) originally, so I knew it worked fine. I tried termosen's response, but to my surprise IGMP snooping was already disabled for both 2.4Ghz and 5Ghz spectrums. I advise using Asus' firmware restoration utility (available at the same place as the firmware under Utilities) to downgrade to mine. It is a bit technical. You need a windows computer to run the utility, you will have to direclty plug your laptop into the router via ethernet (a LAN port, not a WAN port), and then place the router in rescue mode (by unplugging the power, holding down the reset button, and plugging it back in; don't release until the power light is slowly flashing), and then running the utility. Since restoring, my AirPlay works fine. Hope this helps.

have this same exact issue. its weird because if I reboot the router it will work until I stop streaming media again. I tried enabling to see if it holds for me...then ill disable. has anyone reported to asus?

UNKNOVVN,

My problem manifested in exactly the same way. Sometimes the airplay would return on its own. And I doubt ASUS pays much attention to these problems. They likely affect a small percentage of users due to minor variations in the hardware. So any fix would take a long time to come.

new firmware was released on the 13th and sadly it did not fix. looks like reverting is our only choice.

Exact same problem here ...

Usually when I just turn my WiFi on and off my AppleTVs appear ... now they aren't even doing that.

I finally just reverted back to 1.0.1.8n from the ASUS support site and it works flawlessly.

Hi, I had the exact same problem on my Asus RT-N56u and found that enabling "Multicast" traffic fixed it for all my devices (iPhone and iPad). The Asus blocks multicast traffic even over the LAN by default.

iTunes and the devices advertise themselves on a single multicast address of 224.0.0.251 and this was being completely blocked by the Asus router, hence the devices couldn't find each other.

I was in the fortunate position of having two wireless routers and realised that when one worked flawlessly and the Asus didn't that it was definitely something to do with networking and NOT iTunes and my devices.

This could potentially apply to many peoples scenarios on differnet routers. Find the setting that deals with Multicast traffic and make sure it is enabled or allowing multicast traffic and hopefully you'll be sorted.

I used your advice and enabled multicast for both 2.4 and 5 ghz under Wireless > Professional > Multicast to HTMIX 130/144 and not only did it work but music magically started playing through my remote speakers as soon as I applied the settings.

Thanks so much!

3.0.0.4.360 - I once had it drop out but I think it was my laptop was too far away. When I came back closer to the router it wouldn't reconnect, but finally did right away when I turned the wifi on my Mac off and then on again.

I belive I've found the fix!

Enable IGMP Snooping

Here's how:

Wireless (left hand panel-->Professional (tab)-->Enable IGMP Snooping (in the middle of page)

Since I enabled this I haven't had any issues.
