Hello Everyone,
We have a small issue with a Cisco WLC 2504 with Software 7.4.100 running in a house controlling all Audio/Video and entertainment systems.
The issue is as follows:
1. Apple iPhone cannot control wireless devices such as Belkin's Wemo Switches
2. Apple iPhone cannot control uPnP/DLNA type devices such as Smart TV's using the associated app
I can see, via PC, all devices and each of the Wemo devices are pingable.
We have enabled the broadcast forwarding on the controller as well as Multicast (AP and Global) and enabled mDNS. The iPhone can control the Sonos equipment but Sonos is a little more robust than the Belkin Wemo devices when it comes to controller based wireless deployments.
I suspect issues such as roaming between access points on the iphone. However, in a standard non controller setup (IE - Autonomous Access Points), the iphone could control all of these devices perfectly.
Having looked at all the options, this one is a little off normal logic and i am still leaning towards the iphone roaming between AP's. This is such a simple setup - 1) Single VLAN, Single subnet, static routing, WPA2 PSK (AES), Single SSID (hidden), LAP1262's, 3750-E's, No MAC filtering etc and we are not running flex connect
My next move is to configure the controller to reduce the roaming capabilities in such a way that the iphone will need very poor signal before it roams. I have had issues with Apple IOS devices before and had to really tune down the roaming element. I also had issues with WPA2 PSK and roaming with IOS devices but that was supposed to be fixed in IOS 6.1
Short of me going to site with a sniffer, can anyone shed a little light on the above that I may be missing.
Many thanks in advance
Rob
