OEM easy installation
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.
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
Terminal Upgrade Process
mtd write /tmp/openwrt-DSL2650U-squashfs-cfe.bin && reboot
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

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 - ? (can be: 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).
P4 Ethernet port RJ45 1X1 connector without shield
R196, R197, R201, R202 75 Ohm 0805 size smd resistor
С136 Electrolytic capacitor (I used 220uF*16V)
U14 Unknown IC (just short circuit pads 3 & 5)
Adding WPS button Mod
The board involves the installation of a button (SW3) and LED (D2), it is necessary to check.
