The following caveats are resolved in client adapter firmware 5.60.21.
•
CSCei14830—CB20A hangs when using fast roaming and an SSID of more than 16 characters
If you configure an infrastructure access point with an SSID containing more than 16 characters and
then configure a CB20A client adapter with the same SSID and enable fast roaming, the client
adapter associates to the access point. However, the client hangs when the access point’s dot11
interface is closed and then reopened.

CSCei27491—Client experiences Max PSP issues
When the client adapter is using Max PSP mode, it may fail to get a DHCP IP address and may

CSCsa81143—MIC mismatch errors for CCKM with CMIC/CKIP
Message integrity check (MIC) mismatch errors occur when the client is roaming between access
points, the RF coverage is very poor, and Cisco Centralized Key Management (CCKM) is configured
with CMIC/CKIP encryption. These errors tend to occur at the very edge of the cell when the client
could be roaming between two or more access points.

CSCsb47648—Client cycles between association and disassociation
A 350 series client adapter running 5.60.xx firmware may cycle between association and
disassociation with some third-party access points. In some cases, this may result in the link being
unusable.

CSCsb90261—Clients fail to associate to some third-party access points
350 series client adapters running 5.60.08 or 5.60.17 firmware may be unable to associate to some
third-party access points. The problem may result from the client adapter sending its association
request frame with WME and RM information elements, even if the access point’s beacons/probe
responses have indicated that the access point does not support these features.

CSCsb97784—Client sends IP address 0.0.0.0 in response to show dot11 network-map command
350 series client adapters do not provide their IP address to the access point when the administrator
issues the show dot11 network-map command. However, the client adapters do show the correct
IP address when the administrator issues the show dot11 association command.
