My iPhone keeps getting kicked off network - Help please

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

I failed to find a way to show the current TX pwr ... is there a way to check it?

[david_black_594]

It's under the AP group.  Go to Access Points, select the AP Group View by clicking the weird icon on the right (one square on top of another), select the System Default box on the left side of the window.  You should see 2 tabs - 2.4 and 5GHz.  (I'm pulling from memory here so my directions may be off a little)

Click the 5GHz tab, check all channels except 120, 124, 128

If you don't see those channels, go to Admin and Services/System/Country Code and select "Optimize for Performance"

Now go back to the 5GHz tab and clear 120, 124, 128

Set TX Power to the desired value (example -3)

Click the 2.4 tab, uncheck all channels except 1, 6, 11.  

Set Channelization to 20

Set TX Power to the desired value (example -8 or -9)  Should be 5 or 6 less than the 5GHz setting.

Test and see if things improve.  Measure the RSSI in some of the weak spots as described earlier.  Adjust transmit power as needed.

Sorry, I was not precise enough: I meant the result of the  "self-healing" process in terms of automatically reduced TX power.

[jp]

Here's some feedback: I switched smart-roam and Channelfly off, and I am running  self healing since 10 days now. The iPhone users report that the situation did indeed inprove.
I'd still be interested to learn to what values self healing actually adjusted the TX power of my APs.

Thank you.  I will try and report back
