In one of our locations all TC55 devices can not connect to the existing wifi infrastructure.
The AP is Motorola AP-5131 with fw. 220.127.116.11-005R . Encryption in the AP is set to: WPA/WPA2 TKIP .
I have tried both JB and KK images - no success, devices are stuck at "Authenticating..." .
On the same AP we have a dozens MC9596 , MC3190 , MC32NO ( Win CE ) that are connected with the same settings ( pass, encryption etc. ) . The new devices are added to the AP MAC filter / policy .
Based on my initial findings, this seems to be more an Android 4.X issues: Issue 36638 - android - Android 4.1.x Jelly Bean does NOT connect to 802.1x/PEAP WiFi networks - Android Open Source …
Maybe you could provide sw. patch or advice something else to try ?
Issue was resolved after AP firmware upgrade.
