My iPhone keeps getting kicked off network - Help please

[douglas_liman]

This is the log for around the time it was kicked off (I have smart roam on at level 2 btw)

So start from disabling ChannelFly, it alone is capable to get iPhones disconnected. As usually - 2 smart technologies, expecting "standard" behaviour from the other side, don't work together at all. Unfortunately, iDevices are always a pain -- they typically have weaker RF capabilities and always the highest user expectations. Users don't understand that the fact that they have paid a lot for the terminal, don't buy them a better environment, they are equal to any other device there.

I did everything everyone said here - disabled smart roam - no channel fly - lowered transmit power - turned on self healing 

and my phone just dropped the nework and i sat directly under an access point for 3 minutes before it picked it up again

The other detail i did not include is that i am using a 2.4 network for my phone because it gives me more range outside

[david_black_594]

Have you tried using 5GHz only and if so, was the behavior the same? The 2.4 band is full of trashy interference, especially if surrounded by lots of other WiFi networks.   I’m often amazed that it works at all. My guess is that if you switch to 5GHz, you will have much better luck.  If you need more range, you can add another AP or two.

When you say that the iPhone took 3 minutes to connect, do you mean you were trying to access something and the phone’s connection icon just kept spinning and spinning? Just a guess but there could be a lot of congestion on the channel - so much so that the authentication and association management frames are having a real hard time getting through without errors. If you insist on using 2.4, be sure to use channels 1, 6, or 11.  Try to pick the one with the least amount of traffic snd noise. 

[douglas_liman]

It didn’t see any network.  For like two minutes.  The phone call was dropped (I’m in a remote place so I have to use wifi calling).  I would go to settings and neither my 2.4 network I use for the phone nor the 5/2.4 network I use for computer were showing up.  So I’m guessing I would have the same problem on 5 network.   I did select those three channels - all three.  And then I also tried it allowing all channels.  Same problem.  It just happened again ten minutes ago.  Is there a specific log that could tell me what went wrong.  Since I know the exact time 

[douglas_liman]

This is the log from before and after - i notice several things: 1 - i see a smart roam kick off when i have turned off smart roam (what is the ssh way to confirm that it is off?)  2 - a lot of activity around a mac id i don't recognize
