new aironet 1220 dead after firmware upgrade

Hi I have just had shipped 2x aironet 1220B series AP's .

I just went to upgrade there software using


using the web browse to image option , all apeared to go well, but now when the AP reboots it sits with all 3 green led's permanantly on.

it dosnt pick up an IP & I can do nothing with it

If I connect via console I see the follwing during boot

Motherboard: IBM405 200MHz, 8192KB FLASH, 16384KB DRAM, Revision 04

Bootstrap Ver. 1.00: FLASH, CRC 1C914641 (OK)

Initialization: OK

Memory Bank total used left

DRAM 16742624 0 16742624

Config 524288 0 524288

FLASH 7602176 0 7602176

Memory Bank:File address size encoding type flags

Type '=' for main menu.

c -- Copy file

f -- File dir

l -- downLoad file into DRAM

u -- Upload file

p -- xfer Protocol

n -- coNsole

r -- Run

s -- System info.

Unfortunatly all of this is output just bewfore all led's go green it does not accept any input via hyper term & appears to hang at this point ? I have tries reset option but to no avail. It appears I have no way with communicating with the AP at all.

according to the memory bank readout , all my mem is empty /unused ?? can someone explain what the heck is going on ?

Many thanks

Re: new aironet 1220 dead after firmware upgrade

I don't have the solution, just a similar problem. I have 2 AP1220B's that I thought I should upgrade to the IOS firmware. The first went fine, and I have no problem with the result. In fact, it solved a laptop connectivity problem I couldn't fix otherwise with hours of troubleshooting.

The second AP apparently didn't take the upgrade, and it is completely unresponsive with 3 solid green lights on. When connected thru the console using Hyperterminal, I don't even get the boot information that Darren gets. Hyperterminal shows a connection, but there is no data shown with attempted reboot and no response to commands.

I have the sense that there are likely others with the same problem--and others that will have the problem when they go to upgrade to IOS.

I, for one, will be very dissapointed if my $600 AP becomes a paperweight.

I upgraded my AP's and ended up having to remove the wep key and put it back in. Something happened to the wep key. Also, the B radio periodically goes down now.

Hi Gents there is an excellent document that just got posted the other week to step through how to recover from this.

Re: new aironet 1220 dead after firmware upgrade

I found success working through the "Recovery From A Failure" in that document yesterday. The AP is up and running with IOS. I like this solution better than another one I found posted directly on the message board that reinstalled the old firmware so that you can try the upgrage again. The above cited solution installs the IOS firmware directly. THANKS.
