YouHua WR1200JS

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.

Generic Router

FIXME

Getting started with a new Device Page

  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.

Keep the articles modular

  • 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.

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

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

Debricking

→ generic.debrick

Failsafe mode

→ failsafe_and_factory_reset

Basic configuration

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

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

Buttons

→ 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.
