H3C TX1800 Plus / TX1801 Plus / TX1806

One page - one device. Do not put two devices on the same page.
Please create separate pages for each device.

H3C TX1801 Plus is a dual-band Wi-Fi 6 router. Internally it is very similar to TX1800 Plus and TX1806 models. The three (maybe more in the future) models are part of the TX180x series, which various ISPs (e.g. China Telecom) have customized and offered as part of broadband connection plans. These devices, especially used ones, can be purchased relatively cheaply ($10~$30) on major Chinese e-commerce sites (e.g. JD.com/TaoBao.com). With OpenWRT installed, they offer great performance and flexibility at affordable cost.

Installation

→ Install OpenWrt (generic explanation)

TFTP + TTL Installation: 

Although a TTL connection is required for installation, we do not need
to tear down it. We can find the TTL port from the cooling hole at the
bottom. It is located below LAN3 and the pins are defined as follows:
|LAN1|LAN2|LAN3|----|WAN|
--------------------
    |GND|TX|RX|VCC|

1. Set tftp server IP to 192.168.124.99 and put initramfs firmware in
   server's root directory, rename it to a simple name "initramfs.bin".
2. Plug in the power supply and wait for power on, connect the TTL cable
   and open a TTL session (Baud 115200), enter "reboot", then enter "Y"
   to confirm. Finally push "0" to interrupt boot while booting.
3. Edit u-boot env to ensure use the first image slot:
   => setenv bootflag 0
   => saveenv
4. Execute command to install an initramfs system:
   => tftpboot initramfs.bin
   => bootm
5. Backup nand flash by OpenWrt LuCI or dd instruction. We need those
   partitions if we want to back to stock firmwre due to official
   website does not provide firmware download link.
   # dd if=/dev/mtd1 of=/tmp/u-boot-env.bin
   # dd if=/dev/mtd4 of=/tmp/firmware.bin
6. Upgrade sysupgrade firmware.
7. About restore stock firmware:
   flash the "firmware" and "u-boot-env" partitions that we
   backed up in step 5.
   # mtd write /tmp/u-boot-env.bin u-boot-env
   # mtd write /tmp/firmware.bin firmware

Upgrading OpenWrt

→ generic.sysupgrade

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

LuCI Web Upgrade Process

  • 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

Terminal Upgrade Process

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

Specific Configuration

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

Network interfaces

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

Switch Ports (for VLANs)

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

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 H3C TX1801 Plus ? 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.
