Q. Is it necessary to shut off all laptops and other wireless devices

during an AP upgrade?

A. No, there is no need to shut off the devices. An AP upgrade is a safe process, and

everything can remain on. Make sure that you are connected to a TFTP server.

Q. Where can I find instructions on how to upgrade Cisco IOS® on Cisco

Aironet APs?

A. Refer to Working with Software images for instructions on how to upgrade the Cisco IOS

on the AP.

Note: Use the force−reload option with the archive download−sw command.

Note: When you upgrade the AP or bridge system software by entering the archive

download−sw command on the CLI, you must use the force−reload option. If the AP or

bridge does not reload the flash memory after the upgrade, the pages in the web−browser

interface might not reflect the upgrade. This example shows how to upgrade system software

by using the archive download−sw command:

AP#archive download−sw /force−reload /

overwrite tftp://10.0.0.1/image−name

Q. I have an 1100 AP. I want to upgrade the AP radio from IEEE 802.11b

to IEEE 802.11g. If I upgrade the radio in the AP, can I use the existing

PC cards? Or do I need to upgrade the PC cards as well? The cards are

currently 802.11b cards.

A. An upgrade of the 802.11b radio to 802.11g does not result in any performance

enhancement if you only use 802.11b clients. An advantage of a radio upgrade to 802.11g is

that you can connect 802.11b and 802.11g clients with the AP. With the upgrade, the 802.11b

clients connect at 11 Mbps and 802.11g clients connect at 54 Mbps.

Q. How do you set the AP back to its factory default settings?

A. Refer to Password Recovery Procedure for the Cisco Aironet Equipment.

Troubleshoot FAQ

Q. I have made some configuration changes to the AP. When I try to save

the changes, I get this message on the AP: "Error writing new

config file "flash:/config.txt.new" nv_done: unable to

open "flash:/config.txt.new" nv_done: unable to open

"flash:/private−multiple−fs.new"[OK]". What does the message

mean?

A. This error message indicates that there is no space in the Flash to store the new

configuration. Try to delete any old crash files that exist. Or, if there is more than one Cisco

IOS Software version, delete the one that you do not use. This can free some space on the

Flash. Issue the dir flash command in order to determine if there are any old exception
