Scanning Access Points configured with JAPAN Channels

[WLAN]

Hi,

I have configured the below mentioned configuration for my Access Point.
These wireless networks are not appearing in windows client network list. I
have tried explicit scan also. Still it is not showing networks with 184,188
channels. But it is showing all remaining networks.

Country code: JAPAN
SSID for WLAN 1: Wireless Network1
WLAN 1 mode: 5 GHz 54Mbps (802.11a)
WLAN 1 auto channel: Enabled
WLAN 1 channel: 184 (4920MHz)
WLAN 1 alt. channel: 188 (4940MHz)
SSID for WLAN 2: Wireless Network2
WLAN 2 mode: 5 GHz 54Mbps (802.11a)
WLAN 2 auto channel: Enabled
WLAN 2 channel: 188 (4940MHz)

I am using CISCO AIRONET 802.11a/b/g WIRELESS ADAPTER. This problem can
occur due to the following reasons.

(1) Do I need to set any region settings at Adapter?
(2) Does adapter firmware depends upon
country? How do I check the adapter firware?
(3) Is there anything wrong with adapter vendor driver? Do I need to set
anything in driver level for supporting JAPAN channels.

Anyone please help me to identify and resolve the above problem.

Thanks

5GHz is the "A" in a/b/g card, the default config must be B/G 2,4GHz, try to
change the setting in your card software or card driver to use 5GHz.
