Fig. 28. TFTP Server. 

 After the dialog box of the TFTP server program appears, be sure to specify the working 

folder within which the downloaded firmware files reside. 

Make sure the Accept read requests check box of TFTP Server is selected. 

The LAN IP address of the AP and the IP address of the TFTP server must be in the same IP 

subnet for TFTP to work. 

 Due to the unreliable nature of wireless media, it’s highly recommended that the TFTP server 

and the to-be-upgraded wireless AP be connected by Ethernet, and on the same LAN, so that the up-
grade process would be smooth. 

After the firmware is upgraded, be sure to delete the contents of the Web browser cache, so 

that the Web management pages can be shown correctly. 

 A failed upgrade may corrupt the firmware and make the AP unstartable. When this occurs, 

call for technical support. 

If you want to remotely upgrade the firmware of a deployed AP from the Internet, adjust the 

Timeout and Max no. of retries settings of TFTP Server for remote TFTP upgrade to succeed.
