Cisco Cisco Aironet 350 Wireless LAN Client Adapter Guia De Informação
Q. What are possible sources of interference for the radio frequency (RF)
link of my client card?
link of my client card?
A. Interference can come from a number of sources, including 2.4 GHz cordless phones,
improperly shielded microwave ovens, and wireless equipment manufactured by other
companies. Police radar, electrical motors, and moving metal parts of machinery can also
cause interference. Refer to Troubleshooting Problems Affecting Radio Frequency
Communication for more information.

Q. Do autonomous access points (APs) support load balancing with all
Wireless client adapters?
Wireless client adapters?
A. Autonomous APs support load balancing only with Cisco 350 Wireless Cards with Aironet
extensions enabled. Because this is not included in the Cisco Compatible Extensions (CCX)
program, it does not work with any other wireless cards.

Q. How do you turn on logging in Windows Zero Config (WZC) in
Windows wireless clients?
Windows wireless clients?
A. On the client, turn on the EAPOL and RASTLS logs with these commands:
netsh ras set tracing eapol enable
♦
netsh ras set tracing rastls enable
♦
In order to disable the logs, run the same commands, but replace enable with disable. For
XP, all logs are located in %systemroot%\windows\tracing.

Q. I configured a Windows Zero Config (WZC) supplicant with a SSID
name. I have SSID broadcast disabled in the access point (AP). It is
configured for static Wired Equivalent Privacy (WEP). Association with
the AP is fine when this SSID is used. However, once I disconnect the
wireless connection from the wireless network list (windows), it is
removed from the network list. Why is this?

A. The WZC supplicant configuration needs to have the broadcast SSID enabled for this to
work as expected. If broadcast SSID is not enabled, the utility runs into issues of the network
disappearing from the list.

Q. I configured two networks with SSID broadcast enabled in the access
point (AP). However, I can only see one network in the wireless network
list (windows). Is this normal and is there any workaround to see both?

list (windows). Is this normal and is there any workaround to see both?
A. If you use Multiple Basic Service Set Identifier (MBSSID) on the AP, then the AP uses an
offset MAC address to broadcast both SSIDs. Because any broadcast SSID requires the MAC
address of the AP, without MBSSID enabled, you will only see one.

Q. When a client comes back from sleep mode, the client does not get
reauthenticated automatically to the access point (AP). It requires the
entire authenticating process to be restarted. Is this normal?
