- 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
- Select openwrt-DSL2650U-squashfs-cfe.bin file
- 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/brcm63xx/openwrt-DSL2650U-squashfs-cfe.bin sysupgrade /tmp/openwrt-DSL2650U-squashfs-cfe.bin
- If sysupgrade does not support this router, use the following commands.
cd /tmp/ wget http://downloads.openwrt.org/snapshots/trunk/brcm63xx/openwrt-DSL2650U-squashfs-cfe.bin mtd write /tmp/openwrt-DSL2650U-squashfs-cfe.bin && reboot
Basic configuration
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

Main PCB Mods
Adding WAN port
Adding a second Wi-Fi antenna Mod
The board cut section the track going to the built-in antenna (coil on the board), and part of a track udischy in Wi-Fi module and add a screen between the connector / cable external antenna.
Adding LED Mod
D2 - WPS D4 - second USB port D10 - WAN port on CPU |
Adding second USB port Mod
Need to unsolder not getting the circuit elements, such as, USB port, LED (D4), circuitry for power supply. This action turns the device D1 ⇒ D2
Adding WAN port Mod
The board can be arranged WAN port (P4).
Needed parts:
- P4 Ethernet port RJ45 1×1 connector without shield
