Hello,
I believe I have a configuration issue as I've reduced the network complexity down to 5 total devices and the problem is present.
Printer connected via WiFi to IAP325
IAP325 connected to 4 port switch
iPhone attempting to find Airport Printer
DHCP Server
Wifi Connected Roku Player
my iPhone cannot find the airprint printer on the same network
the youtube app on my iphone cannot find the youtube application running on the Roku.
I suspect there is a multicast issue - so I turned the "Broadcast Filtering" option to disabled and no change in luck.
From what I read, I don't think I need ot enable AirGroup under Services but perhaps I do?
Thanks
