Software Update

Software updates are possible only through the serial cable connection. You cannot use the Telnet

have the ability to transfer data using the XMODEM Protocol.

To update the software:

Select Menu 24 - System Maintenance.

Enter 7 to select Software Update.

A message is displayed asking if you want to continue.

Press y and wait for the Debug Mode command prompt.

Enter the command atur and wait.

After about 30 seconds, the router displays the Starting XMODEM upload... message.

Transfer the new software ﬁle to the router using the XMODEM Protocol of your serial

communications software.

Enter the command atgo to restart the router when the router displays the OK message.

Command Interpreter Mode

Select option 8 from Menu 24, Maintenance, to enter the command interpreter mode. This mode

allows you to diagnose, test, and conﬁgure your router using a script or speciﬁed set of commands.

A list of valid commands can be found by typing help at the command prompt. For more detailed

information, check the NETGEAR Web site at http://NETGEAR.baynetworks.com.

Caution:

This procedure deletes the existing software before installing the new

software. Do not attempt to use this menu unless you have the new software version.

Note:

NETGEAR recommends that you change the Manager port baud rate to 38400

before updating the software. Doing so results in an update time of 5 to 10 minutes.
