Wireless Access

What's the difference between SH and WW firmwares?

The differences for now are the two charachters, but where do you see the SH and WW? Do you have a link or example of the software and product you are referring to?

SH:

 This firmware is engineered for United States and Canadian products and to comply with required regulatory standards. Using this firmware on a device outside of the United States or Canada may void your warranty and may render the device unusable. Downloading this software implies the device is geographically located within the United States or Canada.

WW:

This firmware is engineered to comply with required regulatory standards specific to your country. Using this firmware on a device located in the United States or Canada may void your warranty and may render the device unusable. Downloading this software implies the device is geographically located outside of the United States and Canada.

For your device it probably has to do with the radio settings / channel availability.
