Problem, configuring Wi-Fi in Cisco851W

I need to configure my Cisco851W, using WEP encryption with SSID, which anyone can find in wireless network neigborhood.(with Broadcast SSID in Beacon in terms of Cisco)

I am trying to do this simple thing using Wireless Application.

I input name of SSID,

then mark "Broadcast SSID in Beacon",


input IP address,

then mark Static WEP Key,

input Key

and after clicking apply, I see in the bottom of page my SSID with nothing in the column "Broadcast SSID"

And so, when I am trying to browse wireless networks near me with my notebook, I do not see this SSID.

Is it possible to do such thing with this router?

If the answer is yes, then

What I am doing wrong?

Could you please help me.

Thanks in advance.


Below is my config

Re: Problem, configuring Wi-Fi in Cisco851W

Hi Oleg,

Perhaps this is what you are looking for :)

The command that controls the "Broadcast" of the SSID is "guest mode". Have a look;

guest-mode (SSID configuration mode)

Use the guest-mode SSID configuration mode command to configure the radio interface (for the specified SSID) to support guest mode. Use the no form of the command to disable the guest mode.

[no] guest-mode

The access point can have one guest-mode SSID or none at all. The guest-mode SSID is used in beacon frames and response frames to probe requests that specify the empty or wildcard SSID. If no guest-mode SSID exists, the beacon contains no SSID and probe requests with the wildcard SSID are ignored. Disabling the guest mode makes the networks slightly more secure. Enabling the guest mode helps clients that passively scan (do not transmit) associate with the access point. It also allows clients configured without a SSID to associate.


This example shows how to set the wireless LAN for the specified SSID into guest mode:

(config-if-ssid)# guest-mode

This example shows how to reset the guest-mode parameter to default values (no broadcast SSID):

(config-if-ssid)# no guest-mode

From this IOS Command doc;

Hope this helps!

Re: Problem, configuring Wi-Fi in Cisco851W

Thanks a lot, Rob

you point me to the right direction.

Now I can see my SSID in wireless networks list, but I can not connect to it.

When i am trying to connect my notebook waits a couple of seconds, trying to connect and then says smth like that "can't connect to selected network. This network can be out of range. Try to refresh a list of available networks."

Do you have any ideas, how to solve this?
