Abstract: In network devices, during manufacturing, input for designation of a region code to be a non-specific region code is stored in a BIOS memory of the network device, and a specific region code is stored off the BIOS. During boot up, the BIOS is checked for a specific region code to regulate wireless transmissions at a physical location of operation. Responsive to receiving the non-specific region code from BIOS, the specific region code is requested from a region code server based on a network device identifier. Once received, the region code is stored in flash memory, until rebooted or otherwise reset, rather than BIOS.
