Reloading the Access Point Image
If the wireless device has a firmware failure, you must reload the image file using the Web browser
interface or on all access points, by pressing and holding the MODE button for around 30 seconds. You
can use the browser interface if the wireless device firmware is still fully operational and you want to
upgrade the firmware image. However, you can use the MODE button when the access point has a
corrupt firmware image.
