From a Macintosh computer:

Open Telnet from your hard drive.

Go to the File Menu > Open Connection > and in "Host/Session Name" type in the Ethernet IP address of your router.

Click "Connect."

3.Initiate the TFTP file transfer from your router's configuration screens.

(Note: The following example details firmware upgrade via tftp. In order to do this procedure, your router will need to have internet access. You will also need to verify that the WAN IP address of your Netopia is a valid, routable IP address.)

From the Main Menu, go to Quick Menus > TFTP.

Enter the TFTP Server Name "tftp.netopia.com."

Enter the Firmware File Name "nirxxx.bin" and select "Get Router Firmware From Server" and "Continue."

Example: If the latest firmware version is 4.72, the Firmware File Name would be: nir472.bin.

Note: To upgrade daughtercard firmware on the R2020, R7100 or R7200 enter the firmware file name in the "Firmware File Name" field and then hit enter on "Get Wan Module Firmware From Server".

Once the TFTP file transfer has begun, you will see the "TFTP Current Transfer Bytes" increasing.

(Note: If the file transfer fails due to a 'DNS ERROR' verify that the correct DNS Server IP information has been configured in your router.)

Be sure to leave your router alone, and allow the TFTP transfer to continue until complete.

At the end of the firmware download, all the lights on the router with flash for about 30 seconds, and the router will restart itself.

You will need to reinitiate your telnet session to access the router's configuration screens. (Your current telnet session will hang even after the router has restarted itself.)

NOTE: Under no circumstances should you interrupt this process. When you telnet back to your router, the new firmware version supplied at the top of the Main Menu will indicate a successful firmware download. Every release of firmware includes changes, and may include feature variations not applicable with your current configuration. These variations can sometimes cause corruption of the router configuration, which will require you to reset the router to factory defaults, and erase your existing configuration. It is unlikely that you will have to reset your router to factory defaults, however, as a precaution, we recommend that you save either a written copy of your configuration or a configuration file from the Netopia router prior to upgrading the firmware. Your router's configuration file can be saved for backup via either an Xmodem or TFTP file transfer as well.
