ACS is not bad with logging

ACS is not bad with logging information, can you filter with the phone mac address and paste what the ACS log is when phone not connecting, after that boot the phone and reconnect successfully and paste(attach) the logs.

You have to get "debug client

You have to get "debug client <7921_mac_address>" output from your WLC CLI while this issue happening. By looking at that we can see what's going on.

Pls attach that output

First I would die a survey

First I would die a survey with the phone across your problem areas. If you have any bring higher than -67 with your aps on 25-50mw tx power I would first correct that ..

If if that turns out good then you need to make sure you have 25%cell overlap.

I mi would also do a debug on the device and see what is going on from the phone perspective ..
