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 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, 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.

I'm not using a usb to serial, or do I need a usb to serial adapter?
04-14-2014 08:47 AM
For console access.... yes you do and the blue Cisco flat console cable.
04-14-2014 08:56 AM
Okay. I will let you know the update once I have the adapter. Thanks for your help. though.

Actually, I got putty to open. I just have to change the connection type in putty from SSH to Serial. Now the console window opens and it prompt ap>

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.

Here is another doc you can reference:

What do you mean by WLC?
04-14-2014 10:00 AM
Its another device... if you don't have one, then you don't have to worry... just follow the guides I have posted and you will be able to web into that AP and configure it.
