Cisco Cisco Aironet 350 Wireless LAN Client Adapter

Workaround: None.

CSCsj23076—Signal quality in CASSU is not consistent with current signal quality in the ADU

The signal strength quality percentage in the CASSU interface is not the same in the ADU interface. 
When the device is taken out of access point range, the current signal quality is still 100% in the 
ADU, but signal quality is 0% in the CASSU.

Workaround: None.

CSCsj64455—Supported Features Advertisement information element bit 0 is 0 not 1 on the client

When client MFP is disabled on the controller for a particular WLAN, beacons and probe responses 
that originate from APs in this WLAN have the SFA IE bit 0 set to 0. When a client associates with 
WPA version 2(MFP) EAP, the SFA IE bit 0 is 0, not 1. When a client associates with WPA version 
2 (MFP) EAP with CCKM, the SFA IE bit 0 is 0, not 1.

Workaround: None.

CSCsj84780—ADU dimmed after installation

The ADU interface is dimmed even though the CB21AG client adapter is not configured to use 
Windows Zero Configuration (WZC).

Workaround: Uninstall and reinstall the ADU software.

CSCsj85294—Clients with CB21AG at 100% CPU because of DPC and ISR

Wireless clients with CB21AG adapters sometimes run at 100% CPU for extended periods of time, 
which causes slow wireless connections and disconnections. The process monitor spikes to 100% 
CPU utilization because CPU is consumed by Deferred Procedure Calls (DPCs) and ISRs.

Workaround: None.

CSCsk01565—After LEAP domain logon, ADU usually asks for the authentication again

The client uses LEAP security with the automatic prompt option and WPA data encryption. When 
the device is booted up, the user logs onto the domain. LEAP shows the progress of the 
authentication and gets an IP address to log in. After login, LEAP asks for authentication data again.

Workaround: None.

CSCsk04387—PAC expires itself with local RADIUS server even if no expiration date is set

A network has two access points with local RADIUS servers for EAP-FAST authentication. Even if 
the PAC has no expiration date, the PAC expires a few days after the initial authentication.

Workaround: None.

CSCsk07088—WLC shows parsing error when client performs send message test in DC mode

After the client is configured with at least one valid WLAN profile, the client is associated to the 
diagnostic channel. When the client initiates the send message portion of diagnostic channel mode 
testing, the WLC shows a parsing error.

Workaround: None.

CSCsk08004—PC-MY18A computer (NEC MateNX) freezes when the ADU is installed

PC-MY18A computer (NEC MateNX) with PI21AG stalls with ADU installation and must be 
rebooted.

Workaround: None.

CSCsk08053—Destination MAC address invalid with DNS ping test

After you connect CCXv5 client to the infrastructure device, start the DNS ping test from the 
Diagnostics tab and wait for the test results. The MAC address is invalid.
