Hello,

I have a Cisco 877W (ADVIPSERVICESK9-M), Version 12.4(15)T7 and a
Toshiba Laptop with an Intel
Wireless Interface - Intel PRO/Wireless 3945ABG. The
laptop runs Vista.
Toshiba A200-27U
Model No. PSAE6E

I look around occasionally with inSSIDer and from time
to time see a very strange SSID indicated. I understand
that inSSIDer gets its information from the Vista driver
and sure enough :-
c:\>netsh
wlan

netsh wlan>show networks mode=Bssid
(plain show networks is similar with less detail)

gives me :-
(note SSID name should be after "SSID 3 : "
as can be seen in subsequent examples.)

SSID 3 :
Network type : Adhoc
Authentication : Open
Encryption : None
BSSID 1 : 00:00:00:00:00:00
Signal : 99%
Radio Type : Any Radio Type
Channel : 13
Basic Rates (Mbps) :

This is consistent with inSSIDer except that inSSIDer
shows channel 0. Which does not exist. inSSIDer
says SSID "Unknown".

The signal strength is the same as that indicated for
my Access Point which is in the same room.
inSSIDER says RSSI -50. Also the ONLY AP
nearby that is using channel 13 is my own one.
Chanel 13 is legal in the UK. 1-13 are allowed.
No one else uses it so I do.

Anyone any ideas? Note that inSSIDer does not
always show this "rogue" Unknown SSID.

Is my PC opening an Adhoc network to anyone who
happens along?

My Cisco router's entry is:

SSID 2 : bod43
Network type : Infrastructure
Authentication : WPA-Personal
Encryption : TKIP
BSSID 1 : 00:19:56:95:xx:xx
Signal : 99%
Radio Type : 802.11g
Channel : 13
Basic Rates (Mbps) : 1 2
Other Rates (Mbps) : 12 18 24 36 48 54
## I have changed the allowed rates for my own purpose.
## Basically, if at long range use 2M and stick to it
## which I find more reliable than letting it wander.

Another local AP:

SSID 1 : O2wirelessEExxxx
Network type : Infrastructure
Authentication : Open
Encryption : WEP
BSSID 1 : 00:90:d0:f2:xx:xx
Signal : 13%
Radio Type : 802.11g
Channel : 1
Basic Rates (Mbps) : 1 2 5.5 11
Other Rates (Mbps) : 6 9 12 18 24 36 48 54

Thanks.
