Getting started with a new Device Page
- 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.
- 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.
- 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.

OEM easy installation
Flash factory image through stock firmware WEB UI.
Note: Reset router to factory defaults if it has been previously configured.
- Browse to
http://192.168.1.XXX/webpages/pages/userrpm/firmwareUpgrade.htmlIP address depends on DHCP. - Upload
openwrt-ramips-mt76x8-tplink_re305-v3-squashfs-factory.binfile to repeater. Be carefull to usefactoryversion! - Wait for it to reboot (2-3 minutes)
- Via LAN, SSH to 192.168.1.1 and set a root password, or browse to
http://192.168.1.1if LuCI is installed.
Tested with EU/3.0 1.0.1 Build 20190221 Rel. 63495 and “RE305(EU)_V3_200826”

Enter values for “FILL-IN” below
| Bootloader tftp server IPv4 address | FILL-IN |
|---|---|
| Bootloader MAC address (special) | FILL-IN |
| Firmware tftp image | Latest OpenWrt release (NOTE: Name must contain “tftp”) |

Upgrading OpenWrt
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:
sysupgrademtd
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
Failsafe mode
Basic configuration
You can use the device as a
Wireless or wired repeater (Range extender)
Wireless access point (Provide WiFi using cable)
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
Specific Configuration
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)
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

The TP-Link RE305 has the following buttons:
| BUTTON | Event |

| EXAMPLE No buttons at all. | - |
Back to OEM Firmware
To revert the device to the original OEM firmware, follow these steps (adapted from the RE200 guide, also applicable to the RE305 v3):
1. Download OEM Firmware: Obtain the OEM firmware from the official TP-Link Support page. → RE305 V3 Firmware
2. Prepare the Firmware:
Use the tool “tplink-safeloader” from the OpenWrt development environment (Image Builder) to prepare the firmware for a sysupgrade. For example:
build_dir/host/firmware-utils/bin/tplink-safeloader -z oem-firmware.bin -o oem-sysupgrade.bin
Transfer and Flash: Updating via LuCi interface or transfer the resulting file (e.g. via SCP) to the “/tmp” directory on the device, then run:
sysupgrade /tmp/oem-sysupgrade.bin -F → Upgrading OpenWrt firmware using LuCI and CLI
The -F flag forces the upgrade since the OEM firmware does not include upgrade metadata.
Post-Upgrade: After the first reboot, it is advisable to perform an OEM firmware upgrade to ensure the software version is displayed correctly.

Opening the case
DANGER: HIGH VOLTAGE inside!
Opening this device exposes
parts under high voltage (110/230 VAC)!
- Risk of deadly electrical shock
- Risk of irreversable damage to other components attached, e.g. your PC connected via serial
Make sure to keep your fingers, conductive tools and serial cables away from the high voltage at all times!
Capacitors can still retain dangerous voltages
after disconnection from mains!
Continue at your own risk!
Note: This will void your warranty!
