I was updating the firmware on my cisco aironet access point and it froze right in the middle of the flash. When I plug the access point in now, the status light pulses between green, orange and red; the radio light blinks red; and the Ethernet light blinks green. Is there any hope for this access point? I need assistance please!!

If you have a Cisco console cable I would advise plugging it in and opening hyper terminal to see what messages, if any, are showing up during the boot process.

PLEASE READ ALL OF THE STEPS BEFORE ATTEMPTING:

There are a few solutions to try.  First, I would try resetting the access point to factory using the following steps:

Step 1 Disconnect power (the power jack for external power or the Ethernet cable for in-line power) from the access point.

Step 2 Press and hold the MODE button while you reconnect power to the access point.

Step 3 Hold the MODE button until the Status LED turns amber (approximately 1 to 2 seconds), and release the button. All access point settings return to factory defaults.

Once this is complete you will need to either assign a static IP address (using hyperterminal) or connect it to a DHCP server that will assign it an IP address (using the Cisco IP Setup Utility to determine the IP address assigned).  You could also just guess the IP address if your DHCP range is limited.

Once you know the IP address, you can retry the firmware upload.

At this point, let me know if you have a console cable and I will provide steps for you to connect to the access point via hyperterminal.

If there are any prompts for username or password, the factory reset should be set to "Cisco"

If you get a prompt, type the following:

enable
config t
interface BVI1
ip address {IP Address} {Subnet Mask}
end
wr

{IP Address} and {Subnet Mask}, enter the actual IP and Subnet you with to use with a space in between.  From there you should be able to plug in a cat5 and telnet or use a browser to log in and update the firmware.

Let me know if this works for you or if you run into any snags along the way

When I get to the config t....it comes back as "Invalid input detected at ^ marker...and the marker is under the "o" in config. It picked up an ip through dhcp...I can ping it but cannot get to the website for the access point. Thank you so much for helping me with this!!

Ah, yes.  This is what you will need to do...

Have both your console cable plugged in and a cat5 from your machine to the network connection on the access point.  Make sure you placed your firmware image file in your TFTP directory.  You will need to boot the access point up with a hyper terminal window open on your machine.  When it has finished booting and you have a prompt, enter the following:

set IP_ADDR {IP Address}
set NETMASK {Subnet}

NOTE:  IP_ADDR and NETMASK must be in all caps.

Next line type:

tftp_init

This will prepare the access point to accept a TFTP connection and untar the image file:

tar -xtract tftp://{IP address of your TFTP server }/{directory on the TFTP server that contains the image }/{Image File Name} flash:

Here's an example:

tar -xtract tftp://192.168.0.1/images/c1200-k9w7-tar.123-8.JEA.tar flash:

The image will inflate and you need to press the spacebar when the screen fills up or inflating the image will time out.  

Enter the set BOOT command to tell the access point that you want it to use the image that you just untarred.  There will be another directory inside of the untarred directory.  It will look something like this:

set BOOT flash:/c1200-k9w7-tar.123-8.JEA/c1200-k9w7-tar.123-8.JEA

Notice the directory made is just the name of your image minus the .tar extension.  You should be able to enter the command "show flash" if you are unsure of the directory name that was made.  

You can then check your settings be using the "set" command.  If everything looks good, enter "boot" and enter "y" if it prompts you to say yes or no to reboot.  Once it reboots you should be able to login using the browser.  Remember the default username and password will probably be "Cisco"


Let me know.  Good luck :)

I think the access point it beyond this...I try to set the ip address and it gives me "Invalid input detected at ^ marker...and the marker is under the "I" in IP. LOL! Now What? It's pretty bad isn't it!! Thank you again for your help and time!!

Did you use all caps?  One thing I forgot to mention...

Let the access point boot until it begins to inflate the image. When you see these lines on, press Esc:

Loading "flash:/c350-k9w7-mx.v122_13_ja.20031010/c350-k9w7-mx.v122_13_ja.20031010"
...###########################################################################
################################################################################
################################################################################
####################

Then try the steps above.  You can find this information on this link:

alishad,

The firmware you install is for LWAPP APs. Are you using this access point with a controller?

You have loaded the wrong IOS version. You installed the light weight IOS.

Step 1 Log into the CLI on the controller to which the access point is associated and enter this command:

config ap tftp-downgrade tftp-server-ip-address filename access-point-name

(where:
a) tftp-server-ip-address is the IP address of the TFTP server

b) filename is the full path and filename of the access point image file, such as
D:/Images/c1240-k9w7-tar.123-7.JA.tar

c) access-point-name is the name that identifies the access point on the
ocntroller.)

Step 2 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED blinking green.


Step 3 After the access point reboots, reconfigure it using the access point GUI or the CLI.

Just went through this with a 1130 myself thought I would add some info I found out.
1. The .tar file has to be renamed to c1130-k9w7-tar.default
2. Holding down the Mode button for 20-30 seconds until the radio button goes red will cause the access point to look for the tftp server.
3. It may just have been my AP but I watched as it booted while holding down the Mode button and it defaulted to 10.0.0.1 as its IP and 255.255.255.255 as the mask. Which caused the tftp server to fail since it was not on that subnet. To correct the problem I added a 10.0.0.# IP address on the tftp server, restarted the tftp server using the new address, and the AP downloaded the new IOS immediately.
