Introduction

It is possible to restore the 501R to the factory defaults if you have forgotten the administrator password.
This requires physical access to the 501R to use the RS232 console port.

This procedure uses the developer debug interface to the 501R and should be done with caution as experimenting with the other features may irreversibly corrupt the router.
Procedure

1. Connect a RS232 serial cable from your PC to the console port on the 501R.
2. Set your terminal emulator programme to 115 kbit/s, 8 data bits, no parity, 1 stop bit, and no flow control.
3. Reboot the 501R (pull the power plug).
4. Press and hold the A key while the 501R boots up. The following screen will appear:

[I] ADSL Router Information
[S] Software Download (X-Modem)
[E] Erase Current Parameter
[D] Debug Tools
[C] Change Console Baud Rate
[R] Reboot…

5. Press E to erase the configuration and restore to factory defaults. The screen will display:

OlErase success . ..

6.Press Esc then R to reboot
7. Change your terminal emulator programme to 9600 bit/s, 8 data bits, no parity, 1 stop bit, and no flow control.
8.Reprogram the 501R with your configuration. Write to flash and reboot.
