Caveats
•
CSCsg99322—CB21AG client does not roam smoothly between two lightweight access points
A CB21AG client does not roam smoothly between two lightweight access points. If a client
associated with a lightweight access point that has an RSSI of –90 dBm but then tries to associate
with another lightweight access point that has an RSSI of –45 dBm, the client does not roam to the
new AP for between 5 and 10 seconds. During that delay, the CB21AG client sends out a probe
request to which the second lightweight access point responds. However, the CB21AG client does
not send out an association request.

CSCsd80390—The “No machine certificates were found on your computer” message is misleading
When using the Cisco AIR-CB21AG-A-K9 802.11/a/b/g client adapters and running ADU 2.6.0.1,
if you try to select ADU clients using EAP-TLS authentication, you see a message stating that no
machine certificates were found on your computer, even though the application automatically finds
the machine certificates. Also, if you select Use machine Information for Domain Logon under
EAP-TLS configuration, you get the same error message. This message will not cause any problem
and should only be seen once.
