- LAN speed: 10/100/1000
- LAN ports: 4
- WAN speed: 10/100/1000
- WAN ports: 1
- Serial baud rate of Bootloader and factory firmware: 57600

Installation through telnet:
- Copy kernel.bin and rootfs.bin to a USB flash disk, plug to usb port
  on the router.
- Enable telnet with link: http://192.168.1.1/setup.cgi?todo=debug
  (login if required, default: admin password)
- You will see "Debug Enabled!"
- Telnet 192.168.1.1 and login with "root"
- ls /mnt/shares/ to find out path of your USB disk. 'myUdisk' for
  example.
- cd /mnt/shares/myUdisk
- mtd_write write rootfs.bin Rootfs
- mtd_write write kernel.bin Kernel
- reboot

nmrpflash can be used to recover to the netgear firmware if a broken
image was flashed.
