Planex MZK-W04N-XX

CPU: Ralink RT2880F
Flash: 8MB
Wi-Fi: Ralink RT2860 (maybe RT2820 - hard to see) 802.11N, 3 antennas look to be non-removable
Switch: IC+ IP175C 4LAN+1WAN 10/100

Serial console

Serial console is available at 57600 8n1 on J1 (I had to desolder / solder a 0.1" pin header), pinout:

1: VCC (closest to edge of board) (?)
2: RXD (data from PC to router)
3: GND
4: TXD (Data from router to PC)

And then boots to some lame GUI-ish login program…


So I ordered a MZK-W04N instead of the USB equipped MZK-W04NU … The MZK-W04N is a totally different beast. Oops.

I haven't been able to find GPL source for this thing, but it def is running U-Boot and Linux. Seems similar to the Asus RT-N15, Belkin F5D8235-4, Linksys WRT-160N, etc.

===== UPDATE 10/jun/2010 ======

Planex (PCi) W04n-XX is IDENTICAL to Edimax 6524N router. The only difference is ROM & RAM sizes.

How to flash without serial cable: Configure your PC with static IP address between and (ex. Connect your pc to mzk-w04n-xx port 1. Remove the power cable from the router. Press and hold reset button, while inserting the power cable, hold pressing the reset for 10 seconds. Now w04n-xx is accepting tftp flashing on fixed IP

Enjoy. By RyLoS (you can reach me on Press and keep pressed th
