Clearing the Password or Updating the Firmware in Routers Using a Manager Port: RM356, RT311, RT314, RT328, RT338, RH340, and RH348

This procedure uses a terminal emulation program such as HyperTerminal to put the router into boot mode, then sends it the new firmware or default configuration file using the XMODEM file transfer protocol. HyperTerminal is included in the standard Windows installation, under Programs Accessories Communications Hyperterminal.

Updating sends a firmware file to the router. Firmware files are typically named filename.bin, and can be found in the Downloads for a product in under Support in NETGEAR's Web site.

Clearing the password is accomplished by sending a default configuration file to the router. Default configuration files are typically named romfile0 or romfile0.nnn. Your original romfile0 can be found on utility disk that was supplied with the router. If you have updated the router's firmware, use the romfile0 that is included with new firmware.

Download the files to your PC and remember their location. Connect a standard PC serial cable from one of your PC's COM ports to the serial Manager port on the rear of your router, then follow the appropriate instructions below.

Note:

• The FirstGear Configuration Utility cannot be used to upload firmware.
• The RM356 uses a special serial cable that was supplied with the router.
• For a more detailed description of these procedures, refer to the Reference Manual that was supplied with the router.

To Upgrade These Router's Bin File

1. Click Start > Programs > Accessories > Communication > HyperTerminal.
2. In Connection Description enter a name of your choice.
3. Click OK.
4. In the Connect To window select Direct to COM1 in Connect using, and click OK.

Data bit	8
Parity	None
Stop bits	1
Flow control	Hardware

6. Click OK. A HyperTerminal Screen displays.
7. Power cycle the router and when the power is turned on, you will notice the session completing a test. When the window reads "PRESS ANY KEY TO ENTER DEBUG WITHIN 3 SECONDS" press any key. If you are late, then recycle the power and try again.
8. Once you enter the debug mode type the command atur and quickly press ENTER. (Some users have reported that atur does not work, and atur3 should be used, instead.) This message appears “Starting XMODEM upload (CRC mode)...."
9. When you see characters like "CCCCCC……CCC" go to the TRANSFER option on the top menu bar and click Send File > Browse.
