Airwaves Survey shows duplicate entries per WLAN SSID

Hello Cisco WLAN-experts,

I have a nice problem for You:

Our WLAN-networks appear twice in every WiFi-Catcher !

We are running 1131LAPs in HREAP-Mode together with a 4402WLC and use two WLANs. One is the typical "Guest WLAN", another a more secure one, which we do not broadcast the SSID from.

Both 802.11b/g and 802.11a are active.

To our surprise, our 802.11b/g-only WLAN-clients see 4 instead of the expected 2 WLANs while they use tools like Airwaves Survey to scan the surrounding.

The shortened output looks likes this:

RSSI BSSID SSID Type

-44db 00-1f-9e-7f-e1-60 802.11g

-40db 00-1f-9e-7f-e1-61 guest 802.11g

-40db 00-1f-9e-7f-e1-62 guest 802.11g

-39db 00-1f-9e-7f-e1-63 802.11g

Does anybody have an explanation why the Cisco LAP is appearing with 4 different Mac-addresses in our Clients ?

Thank You for any hint in advance.

Greetings from Good old Germany

Here You can see the screenshot.

You will see that because users need to see a different mac addess per radio and per ssid. So if you have one ssid and that ssid enabled on both radio's, then you will see two mac address entries. If you only had that on one radio, then you will only see on mac address entry. Hope this helps.

Hello Fella,

thank You for this remark.

Yes we have 2 SSIDs on the 2 radios 802.11a and 802.11b/g

But why are the 4 entries all stating 802.11g ?

Are you seeing 4 also from the 802.11a or is the software not detecting the RF correctly.

No, we do not see entries from the 802.11a network. The used WLAN-cards only support 802.11b/g for which duplicate entries are shown.

Don't know why then.... you might have to open up a case with Dell or whomever is supporting that utility.
