We are facing an issue where all our 802.11b Clients are stuck in Status "Probing". Please see the attachment (WLC_3_80211b_probing.JPG)
802.11b is already enabled, and we have changed the 11mbps data rate setting from "Mandatory" to "Supported" as per some older posts on this forum.
The controllers Wireless >> 802.11b/g/n >> Network settings can be seen attached (before the 11 mbps change)
I have also attached "debug client <mac-addr>" output from one 802.11b client (001cbfbe2fc4.txt )
Please let us know the possible resolutions for this issue.
