ASUS WL-330N & WL-330N3G
Ralink RT3050F
The device is a mobile 150Mbit wireless N router with
- Single Internal antenna
- Single 100/10 Ethernet Interface
- 4 MB Flash
- 32 MB SDRAM
- WL-330N is supported since R31100 Note by JayBeOh: Use the 3G-.bin file for this device as well. There is a file specifically created for this device but it does not work (at least not when flashing via Recovery mode)
- WL-330N3G is supported since: R31450
- Both supported by Attitude Adjustment 12.09: download firmware (same for both according to above comments, tested on 3G only)

Opening the case
Note: This will void your warranty!
- There is one screw underneath the serial and mac sticker on bottom of the device.
- Sides of plastic case are held together with small clips. Three on both long sides, two on end with no connectors.
The case can be very difficult to open, but be careful not to destroy the plastic in the process as the case makes up half the body of the Ethernet socket.
Serial
The serial port on bottom side of PCB, left from USB port. There's two solder pads marked with TX and RX. Be careful when soldering and add drop of glue to prevent pulling fragile pads from pcb.
Settings: 57600N8, 3v3 TTL
Note: The pads may be covered in solder mask, in which case you will have to carefully scrape them clean with a sharp blade or tweezers before soldering.
JTAG
JTAG pins can be seen after removing metal RF shield. Location and number of pins match with Ralink datasheet JTAG info. Functionality of JTAG has not been tested.
Installation
Note: OpenWrt supports this device since Attitude Adjustment 12.09.
Note: Be carefully while installing version 15.05.1 cause there's broken wireless security and it discover yourself after a hour since you connected to AP.
Note: Correct work with HUAWEI HiLink devices avaliable since LEDE 17.01.4.
Installation using console port
- download a stable image
- or build your image from SVN trunk(Target: Ralink RT288x/RT3xxx, Subtarget: RT305x based boards, Target Profile: Default Profile)
- Prepare a TFTP-Server and place the openwrt-ramips-rt305x-wl-330n3g-squashfs-sysupgrade.bin (or bin/ramips/openwrt-ramips-rt305x-wl-330n-squashfs-sysupgrade.bin) in its directory
- Rename the binary to test.bin (longer filename failed once, test.bin is the default)
- Connect to serial port (57600N8)
- Power-ON your WL-330N3G (or WL-330N)
- When asking “Please choose the operation” enter “2” (Load system code then write to Flash via TFTP.)
- fill out (WL-330N3g-)device and (TFTP-)server IP-Adresses
- enter the filename: test.bin
Press enter and wait until flashing is complete and the device reboots. The OpenWrt should be accessible on it's default IP (192.168.1.1).
Recovering should be possible as the bootmanager is not overwritten.
Installation using recovery mode
Note: Tested on WL-330N3G.
It is possible to load an OpenWrt or LEDE image this way, e.g. bin/ramips/lede-17.01.4-ramips-rt305x-wl-330n3g-squashfs-sysupgrade.bin. The example uses a firmware image downloaded from ASUS, it has a .trx extension, but the format is the same as the OpenWrt/LEDE image. The ASUS WEB-interface firmware update page does not accept an OpenWrt/LEDE image, it probably checks the image header. In the ASUS header the router model is specified, the OpenWrt/LEDE header does not include the router model.
- Connect the router to the Ethernet port of your computer.
- Power on your Router and press the restore or WPS button
- Keep holding the restore or WPS button approx 7 seconds more until the power LED blinks slowly (about 0.2 Hz). If you are running tcpdump on the Ethernet interface you should see ARP requests from 192.168.1.1 for 192.168.1.20.
- Configure your Ethernet IPv4 address as static: 192.168.1.20 netmask 255.255.255.0. Note the IP of .20 is critical - the bootloader accepts tftp only from this IP.
- Use tftp to upload a firmware file in binary mode to the device:
Under Windows this can be done with “tftp -i 192.168.1.1 put WL-330N3G_1.0.2.0.trx”.
Under Linux you can use the “tftp 192.168.1.1” command, on OpenWrt devices you can use tftp-hpa and send the following commands:
# tftp 192.168.1.1 tftp> binary tftp> trace Packet tracing on. tftp> rexmt 1 tftp> put lede-17.01.4-ramips-rt305x-wl-330n3g-squashfs-sysupgrade.bin sent WRQ <file=lede-17.01.4-ramips-rt305x-wl-330n3g-squashfs-sysupgrade.bin, mode=octet> received ACK <block=0> sent DATA <block=1, 512 bytes> [...] sent DATA <block=5377, 4 bytes> received ACK <block=5377>
Instead of the openwrt or lede image (lede-17.01.4-ramips-rt305x-wl-330n3g-squashfs-sysupgrade.bin) you can upload other images (eg. the original ASUS-Firmware: WL-330NG_1.0.2.0.trx).
- Wait, flashing may take a couple of minutes. Do not power off!
- The device will reboot when flashing is done. If you flashed OpenWrt/LEDE, telnet into 192.168.1.1 and set root password according to Log into your Router Running OpenWrt.
