Reset Cisco 1140 Access Point

Hi,

 

I need help resetting the Cisco Aironet 1140 model AIR-LAP1142N-A-K9.  I need to access its web browser but I don't know the password.  I perform the mode reset method, but that didn't do anything.  Maybe I have to access its CLI, but that I don't know how.  Any help would be gladly appreciate. 

Thanks.

Hi,Default username password

Hi,

Default username password for AP is Cisco/Cisco.

From the model name it looks like your AP is in lightweight mode "AIR-LAP1142N-A-K9".

Now two things:

1.) Is you need to access it via CLI:

telent/ssh is disabled on LWAP(lightweight APs) by default. We can only access them via console cable unless they get registered to a controller.

2.) If we have to access the Web interface of the AP then we have to first convert these LWAPs to autonomous mode. There is no web GUI in LWAPs and for the conversion process we'll need console connection to the AP.

 

Thanks,

Ishant

Hi Ishant,

I am having a hard time accessing the CLI.  Once I plug the RJ-45 into the AP and the com port into the PC, where do I go from here?  Oh, and thanks for your prompt reply.

Do you have the correct console cable and the com port setting?

What do you see from the output from the console?  You need to be able to get into the console in order to help you figure out the issue.

Hi Scott,

The setting for the COM1 is 9600, 8 data bits, 1 stop bits, none parity, and XON/XOFF flow control.  So when I open putty and click open, nothing happens.  And yes, I am using a female db-9 to RJ-45 cable.

If you don't see any output,

If you don't see any output, then try a different usb to serial and or a different machine.  The usb to serial seems to be an issue to many when accessing any Cisco wireless equipment.  Other equipment seem fine.

So by this, you have an autonomous AP, which is good, unless you have a WLC.  So now, you need to configure the AP.  Here is the 1142 Getting Started Guide to walk you through the configuration.

ah, ethernet was disconnected

ah, ethernet was disconnected.  So once I plug it in, I manage to obtain its ip address and access its web GUI.  I created its ssid, enabled WPA and enter its "RADIUS server" by ip address and "RADIUS Service Secret", also enabled "Broadcast SSID in Beacon".  I scan my wireless network to see if the ssid is there, but it doesn't show up.

Hall of Fame Super Silver

You need to post your show

You need to post your show run-config

You have to add the ssid to the radio and its probably a good idea to start easy... create an ssid with WPAv2 and pre-shared key and test with that.

The show run-config doesn't work.  I type "show ?" but I don't see that option in the list.

How are you configuring this

How are you configuring this AP.... console or GUI?  Just make sure you create your ssid, assign it to the vlan and apply it to the radio.

By GUI.  So when I enable vlan ID, it is asking for the number ranging 1-4094, or should I click "Native VLAN"?

Native Vlan is used if your

Native Vlan is used if your not tagging that Vlan.  The AP management should always be native, so I would check that.

Hi,

 

Yes we can. If you are in cli of AP just get the output of "show run" and copy the output and paste this on the new AP. You may have to change the ip address of the AP.

 

Thanks,

good news, I manage to setup

good news, I manage to setup the ap with WPA configuration.  Bad news is whenever I unplug the power, it resets everything and I have to set it up again.  Is there a power option where the settings are saved when you unplug the power?

Cisco Employee

Good to hear that AP is

Good to hear that AP is working as per your requirement :)

 

Are you  saving the configuration? Have to enter "wr" to save the configuration from CLI.

Just type ap>wr?

Thank you so much for all

Thank you so much for all your help.  Now I just need to configure the other AP, just need to change the ssid's password.  How would I do that on the GUI?
