ZyXEL NWA55AXE

Under Construction!
This page is currently under construction. You can edit the article to help completing it.

Write a short, relevant description of the device. Include a technical overview, but avoid marketing buzzwords/useless stuff. Two to four sentences is about right. A picture is good, too. Edit the page to see how to add pictures.

FIXME Any text with a light background (like this one) provides instructions for creating the Details Page. When you have filled in correct/useful information (instead of any template that's there) remove the instructions, as well as the <WRAP> that encloses it.

FIXME

  1. This is an empty template that suggests the information that should be present on a well-constructed Device Page. This means, that you have to fill it with life and information.
  2. There are several “fixme” tags with text on a light background (like this text) throughout this template. As you fill in the page, remove those tags so that people can judge its completeness.
  3. When there are no more “fixme” tags left, delete this one too, along with the <WRAP> that encloses it.
  • Please include only model specific information, omit bla,bla and put everything generic into separate articles
  • If you have no time to write certain stuff, link to docs
  • base-system should lead the way, do not explain this again
  • DO NOT provide a complete howto here! Instead groom the general documentation.

FIXME

  1. The tables below are automatically generated, once the correct filters for Brand and Model are set.
  2. If the tables below show information for ZyXEL NWA55AXE , everything is OK and you can delete this text and the <WRAP> that encloses it.
  3. If the tables below contain “Nothing found”, it means that either
    1. the dataentry page for ZyXEL NWA55AXE is missing. Please create a new dataentry page first, then reload this page. The tables should then contain $something. If they do, delete this text and the <WRAP> that encloses it.
    2. filters are not set correctly. Most common reason for “Nothing found”: The dataentry does not contain a Version, but we are filtering here for version → Please edit this section and adjust the filters with the proper Brand, Model and Version. In case the dataentry does not contain a version, delete the line filter : Versions~. Just try, it's easy. The tables should then contain $something. If they do, delete this text and the <WRAP> that encloses it.
  4. If the tables still contain “Nothing found”: Don't panic, calm down, take a deep breath and contact a wiki admin (tmomas) for help.

None at this time.

Web UI

  1. Connect to the device via lan
  2. Set your IP to `192.168.1.20`
  3. Open Web UI at `192.168.1.2`
  4. Login with username “admin” and password “1234” in standalone mode
  5. At maintenance/firmware-package upload the factory image (see Techdata: ZyXEL NWA55AXE)
  6. The device should reboot into openwrt an be accessible via `192.168.1.1`

As the device uses a dual-image partition layout, OpenWrt can only installed on Slot A. This requires the current active image prior flashing the device to be on Slot B.

If the currently installed image is started from Slot A, the device will flash OpenWrt to Slot B. OpenWrt will panic upon first boot in this case and the device will return to the ZyXEL firmware upon next boot.

If this happens, first install a ZyXEL firmware upgrade of any version and install OpenWrt after that.

TFTP

This installation routine is especially useful in case

  • unknown device password (NWA55AXE lacks reset button)
  • bricked device

Attach to the UART console header of the device. Interrupt the boot procedure by pressing Enter.

The bootloader has a reduced command-set available from CLI, but more commands can be executed by abusing the atns command.

Boot a OpenWrt initramfs image available on a TFTP server at 192.168.1.66. Rename the image to owrt.bin

 $ atnf owrt.bin
 $ atna 192.168.1.88
 $ atns "192.168.1.66; tftpboot; bootm"

Upon booting, set the booted image to the correct slot:

 $ zyxel-bootconfig /dev/mtd10 get-status
 $ zyxel-bootconfig /dev/mtd10 set-image-status 0 valid
 $ zyxel-bootconfig /dev/mtd10 set-active-image 0

Copy the OpenWrt ramboot-factory image to the device using scp. Write the factory image to NAND and reboot the device.

 $ mtd write ramboot-factory.bin firmware
 $ reboot

FIXME Find out flash layout, then add the flash layout table here (copy, paste, modify the example).

Please check out the article Flash layout. It contains examples and explanations that describe how to document the flash layout.

Upload the Factory image using the devices web interface.

As the device uses a dual-image partition layout, OpenWrt can only installed on slot A. This requires the current active image prior flashing the device to be on slot B.

If the currently installed image is started from slot A, the device will flash OpenWrt to slot B. OpenWrt will panic upon first boot in this case and the device will return to the ZyXEL firmware upon next boot.

generic.sysupgrade

FIXME These are generic instructions. Update with your router's specifics.

  • Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
  • Upload image file for sysupgrade to LuCI
  • Wait for reboot

If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading:

  • sysupgrade
  • mtd

Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

sysupgrade

  • Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc

mtd

If sysupgrade does not support this router, use mtd.

  • Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot

Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

FIXME Please fill in real values for this device, then remove the EXAMPLEs

The default network configuration is:

Interface Name Description Default configuration
br-lan EXAMPLE LAN & WiFi EXAMPLE 192.168.1.1/24
vlan0 (eth0.0) EXAMPLE LAN ports (1 to 4) EXAMPLE None
vlan1 (eth0.1) EXAMPLE WAN port EXAMPLE DHCP
wl0 EXAMPLE WiFi EXAMPLE Disabled

FIXME Please fill in real values for this device, then remove the EXAMPLEs

Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.

Port Switch port
Internet (WAN) EXAMPLE 4
LAN 1 EXAMPLE 3
LAN 2 EXAMPLE 2
LAN 3 EXAMPLE 1
LAN 4 EXAMPLE 0

hardware.button on howto use and configure the hardware button(s). Here, we merely name the buttons, so we can use them in the above Howto.

FIXME Please fill in real values for this device, then remove the EXAMPLEs

The ZyXEL NWA55AXE has the following buttons:

BUTTON Event
EXAMPLE Reset reset
EXAMPLE Secure Easy Setup ses
EXAMPLE No buttons at all. -

FIXME

  1. This table is automatically generated, once the correct filters for Brand and Model are set.
  2. If you see “Nothing.” instead of a table, please edit this section and adjust the filters with the proper Brand and Model. Just try, it's easy.
  3. If you still don't see a table here, or a table filled with '¿': Is there already a Techdata page available for ZyXEL NWA55AXE ? If not: Create one.
  4. If you see a table with the desired device data, everything is OK and you can delete this text and the <WRAP> that encloses it.
  5. If it still doesn't work: Don't panic, calm down, take a deep breath and contact a wiki admin (tmomas) for help.

Remove the two screws indicated:

Slide the PCB tray out from the outer housing as shown:

Main PCB:

port.serial general information about the serial port, serial port cable, etc.

The Serial Port of this specific device is indicated by the red ellipse:

The board may not come with header pins attached. In this case, remove the four screws indicated in blue. You may also want to either unplug the antenna cables, or remove the nuts holding the RP-SMA ports in place in the plastic housing. Remove the PCB to allow soldering the header pins from the back side of the board.

The pinout is pretty obvious, but just in case:

V Vcc: board voltage (~3.3V; do not connect)
T TxD: signal transmitted from device to host PC
R RxD: signal received at device from host PC
G GND: ground
Serial connection parameters ZyXEL NWA55AXE
Baud rate 115,200
Data bits 8
Stop bits 1
Logic level 3.3V
