Installation
Flash Layout
Please check out the article Flash Layout. It contains an example and a couple of explanations.
OEM easy installation
Get the firmware openwrt-96348GW-generic-squashfs-cfe.bin
- Unplug the power cord
- Press the reset button, don't release it yet!
- Plug the power cord
- Wait 10 seconds
- Release the reset button
- Browse to http://192.168.1.1
- Upload .bin file to router
- Upgrade the image
- Wait for it to reboot
- Telnet to 192.168.1.1 and set a root password, or browse to http://192.168.1.1 if LuCI is installed.
OEM installation using the TFTP method
If you want to upgrade using TFTP you follow these steps (as an alternative to the above install process.
Upgrading OpenWrt
If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
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
- Login as root via SSH on 192.168.1.1
- Use the following commands to upgrade.
cd /tmp/ wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc
- If sysupgrade does not support this router, use the following commands.
cd /tmp/ wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot
Basic configuration
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
Specific Configuration
Interfaces
The default network configuration is:
| Interface Name | Description | Default configuration |
|---|---|---|
| br-lan | LAN & WiFi | 192.168.1.1/24 |
| eth0 | LAN ports (1 to 4) | None |
| wlan0 | WiFi | Disabled |
Switch Ports (for VLANs)
This is an example to configure the switch: numbers 0-2 will be lan, labeled as Ports 1-3 on the unit, number 3 will be the Internet (WAN), 5 is the internal connection to the router itself. Don't be fooled: vlan0 = eth0.0, vlan1 = eth0.1 and so on.
| Port | Switch port | Mode |
|---|---|---|
| LAN 1 | 0 | lan |
| LAN 2 | 1 | lan |
| LAN 3 | 2 | lan |
| LAN 4 | 3 | Internet (WAN) |
# path: /etc/config/network
# port 4 = WAN
