Issue converting a 881W from LWAPP to Autonomous mode

Hi everybody,

It may stupid but I was trying to upgrade the IOS image of the AP and I did a wrong manip.

I downloaded the IOS image (ap801-rcvk9w8-tar.124-10b.JA3.tar) from my TFTP server to the flash of the AP. Everything went find so far.

But than I did an archive archive download-sw /overwrite ap801-rcvk9w8-tar.124-10b.JA3.tar and my AP reboot in LWAPP mode.

I should have done: archive download-sw /overwrite tftp://10.0.0.1/ ap801-rcvk9w8-tar.124-10b.JA3.tar instead!

Now I don't how to go back to autonomous mode. archive commando is not available anymore in LWAPP mode.

Any ideas?

Best regards,

Laurent

Re: Issue converting a 881W from LWAPP to Autonomous mode

A bit more details to my previous post to help you troubleshoot my issue.

On the router (881W) I did :

881W#service-module wlan-ap 0 reset bootloader

so I could access the bootloader of the AP. Now I have the following prompt:

ap:

I did format all the flash with this commando:

ap: format flash:/


Are you sure you want to format "flash:" (all data will be lost) (y/n)?y
flashfs[0]: 0 files, 1 directories
flashfs[0]: 0 orphaned files, 0 orphaned directories
flashfs[0]: Total bytes: 31481856
flashfs[0]: Bytes used: 1024
flashfs[0]: Bytes available: 31480832
flashfs[0]: flashfs fsck took 43 seconds.
Filesystem "flash:" formatted

But now I don't know how to load the correct IOS image on the AP to go back to autonomous mode. Any ideas?

Best regards,

Laurent

Re: Issue converting a 881W from LWAPP to Autonomous mode

Well actually I solve the problem. I just want to explain what I did for people who are running in the same kind of problem.

First of all in the AP bootloader I did:


ap: ether_init
Initializing ethernet port 0...

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

ap: flash_init

Than I checked 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

Than I configured my PC on the same subnet and on the router I 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

!

Than I did 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 my PC IP where I have an TFTP server.

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

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

Than you should be find.

Don't forget to rate the post if you think it is useful.

Perfect. Thank you for your

Perfect. Thank you for your help. I applied this method to convert AIR-CAP2602E-A-K9 to Autonomous Mode witch image ap3g2-k9w7-tar.152-2.JB.tar.

I had a error:

Error writing flash://ap3g2-k9w7-mx.152-2.JB/Y5.bin (Not enough space on device)

I did format the flash with command: format flash:/

This process take very long time (1 hours), but is successfully.
