Cisco Cisco Aironet 350 Wireless LAN Client Adapter Release Notes

The following caveats are resolved in client adapter firmware 5.60.22.

CSCsd77174—350 clients cannot roam if there are too many access points

Wireless clients might become stuck during roaming. Wireless sniffer traces show that the 350 does 
not send out authentication requests after it receives probe responses. The ACU table that tracks 
access points that the 350 hears is full.

CSCse23905—Broadcast key rotation causes Windows ID4201 event

When the Windows client uses the ACU as a supplicant and the access point is configured to use 
broadcast key rotation, ID4201 logs are generated on the client's event viewer every rotation period.

If you are a Cisco registered user, you can use the Cisco TAC Software Bug Toolkit, which consists of 
three tools (Bug Navigator, Bug Watcher, and Search by Bug ID Number) that help you to identify 
existing bugs (or caveats) in Cisco software products.
