Hi all, I played a bit with Channel bonding and mobile devices. I noticed that when I enable 40mhz settings in the radio profile for 5ghz settings, my mobile devices refuses to connect at 5 Ghz and reverted 11ng instead, this happens to my iphone 5 and my Android devices (LG Optimus G). The moment I revert back to 20 mhz settings, they connected back at 11na settings again. What would be the config needed to get them connected at 40mhz under 5Ghz?

What version of iOS are you running on the iPhone? If you are running a 5.x version it needs to be 5.1.1 or later. For the 6.x version it needs to be 6.0.1 or later.

iOS has a "troubled" history with wireless and I have had to reset the network settings on a number of iPhones to get them connected (Settings > General > Reset > Reset Network Settings).

When you enable 40 MHz channels in the 5 GHz spectrum you will notice that the reported 5 GHz RSSI will drop by around 7-15 dBm. This is one of the costs of enabling 40 MHz channels. I have found with some devices that if you have the SSID broadcast on both the 2.4 and 5 GHz spectrums the 5 GHz RSSI drop caused by the use of 40 MHz channels can be enough to make the mobile device associate on 2.4 GHz rather than 5 GHz.

* Have you enabled band steering?

* If you create a SSID that is only broadcast on the 5 GHz radios will your mobile devices connect to it?
