Cisco 800 Series Aironet AP fix

Cisco 800 Series Aironet AP fix

Issue converting a 881W from LWAPP to Autonomous mode

We finally figured this out and thought it would be a great thing to share.

First of all in the AP bootloader:

ap: ether_init
Initializing ethernet port 0…

ap: tftp_init
tftp_init success: You can now use tftp file system!

ap: flash_init

Then check the IP address of the AP:

ap: set
DEFAULT_ROUTER=10.0.0.1
IP_ADDR=10.0.0.1
NETMASK=255.255.255.224

Then configured your PC on the same subnet and on the router and configured the switchport F0 to be on the same subnet as the AP:

interface FastEthernet0
switchport access vlan 2
!
interface wlan-ap0
description Service module interface to manage the embedded AP
ip unnumbered Vlan2
!
interface Wlan-GigabitEthernet0
description Internal switch interface connecting to the embedded AP
switchport access vlan 2
!
interface Vlan2
ip address 10.0.0.2 255.255.255.224
!

Then in the bootloader:

ap: copy tftp://10.0.0.5/ap801-k9w7-tar.124-21a.JY.tar flash:/ap801-k9w7-tar.124-21a.JY.tar

where 10.0.0.5 is your PC IP where you have a TFTP server.

Once you have downloaded it you have to extract the image (Verify to download the right one. Not the LWAPP one)

ap: tar -xtract flash:/ap801-k9w7-tar.124-21a.JY.tar flash:/

It can take a while.

Once it is extracted just type:

ap: boot

Then you should be fine.
