Hi, my question is how we can upgrade firmware of Air AP 1242AG-E-K9 ?
I am with these things:
-Cisco console cable
-Cisco Air AP 1242AG-E-K9
-Cisco Poe adapter
-Cisco AP antennas
- And I am with access to Cisco resources to download firmwares.
But how I can install new firmware?
Am I on the right way?
First I find that link:
https://www.cisco.com/c/en/us/support/wireless/aironet-1240-ag-access-point/model.html#~tab-downloads
I want Lightweight AP IOS Software.
And I should download it:

You really, really need to read this: FN - 63942 - Wireless Lightweight Access Points and WLAN Controllers Fail to Create CAPWAP/LWAPP Connections Due to Certificate Expiration - Software Upgrade Recommended
The AP is probably >10 years old and the MIC has expired. This is why the AP won't join the controller.

Can I do it offline without connection to wireless controller ?

I don't understand the logic.
Yes, the CAPWAP IOS can be upgraded without the WLC, HOWEVER, once the AP joins the controller, the controller will downgrade/upgrade the IOS (found in the AP) so it will be in line with the controller.

Hi.
I don't know the password for enable mode of access point.
How we can reset and upgrade this access point to lightweight from autonomous ?
I downloaded image file for lightweight ios.
I started tftp server on my window 7 pc.
I changed my IPV4 settings to 10.0.0.2 255.0.0.0.
I turned off AP.
I pushed mode button and hold it for 20 seconds when I tuned on AP.
And nothing....... I see only
process_config_recovery: set IP address and config to default 10.0.0.1
process_config_recovery: image recovery
image_recovery: Download default IOS tar image tftp://255.255.255.255/c1240-k9w7-tar.default

When I put my pc and Ap in network 10.0.0.0 255.0.0.0.
I see I don't have connection between them.
My Pc is joined to Domain and when I change my IPV4 settings I see my network type is public, and I can't change it.
Is this my problem?
I put my downloaded image in root dir of tftpd application.
Cctr+break and ESC they didn't work.....

Thank you.
But can you tell me more about how to put new IOS without risks to break the AP?
Now I used tftp server but it is not recommended because UDP is not securely to transfer the IOS firmware from one host to Cisco AP?
About my problem early with tftp I solve it with BVI1 interface, and I put there ip 10.0.0.1 255.0.0.0 and in my PC I put ip 10.0.0.2 255.0.0.0.
Now I am ready to connect AP with lightweight IOS firmware to my switch, where I receive for example vlan 10 where my controller is communicate too. To port where I will connect AP I just will setup access port for vlan 10 am I right?
Now my AP will find the controller?
Or really I need to do these things?:
Using DHCP option 43 or via the CLI on the AP enter the WLC name & IP address.
capwap ap primary-base (WLC-Name) x.x.x.x
Tomorrow I will try, thank you for all your answers .
