> Via TFTP:
> 1. Set your computers IP-Address to 192.168.1.75.
> 2. Power up the Router with the Reset button pressed.
> 3. Release the Reset button after 5 seconds.
> 4. Upload OpenWRT sysupgrade image via TFTP:
>  > tftp -4 -v -m binary 192.168.1.1 -c put <IMAGE>
> 
> Via SSH:
> Note: User/password for SSH is identical with the one used in the
> Web-interface.
> 1. Complete the initial setup wizard.
> 2. Activate SSH under "Administration" -> "System".
> 3. Transfer the OpenWrt sysupgrade image via scp:
>  > scp owrt.bin admin at 192.168.1.1:/tmp
> 4. Connect via SSH to the router.
>  > ssh admin at 192.168.1.1
> 5. Write the OpenWrt image to flash.
>  > mtd-write -i /tmp/owrt.bin -d linux
> 6. Reboot the router
>  > reboot
