TP-Link TL-WDR3600

Dual Band (concurrent) and Gigabit Ethernet. Advertised as 600 Mbps it is Dual-Stream (2×2) on the 2.4 Ghz Band and Dual-Stream (2×2) on the 5 Ghz Band. This wiki entry is fairly brief, but most things in the TP-Link TL-WDR4300 wiki entry apply here.

The latest firmware available is the release build Chaos Calmer 15.05 (sysupgrade link), with working ethernet and dual-band wireless (disabled by default).

With the WDR3600 router, there is a catch: the stock firmware is obtained from the OEM: http://www.tplink.com/en/support/download/?model=TL-WDR3600

The most easy way to revert the WDR3600 back to stock firmware is by flashing the original firmware version TL-WDR3600_V1_130129. With this firmware version there is no need to cut off some pieces before flashing.

So after downloading the firmware package unpack it and you got the file wdr3600v1_en_3_13_26_up(130129).bin

In the next step you copy the firmware over to the device:

scp /path/to/the/file/wdr3600v1_en_3_13_26_up(130129).bin root@192.168.1.1:/tmp/factory.bin --> or whatever ip you've set

after that you log into the router:

ssh root@192.168.1.1

Finally you write the firmware with:

mtd -r write /tmp/factory.bin firmware

Wait a while, it takes some time. No further steps needed. It is suggested to reset your current configuration before reverting to the stock firmware. This might work as well if you try to go from gargoyle firmware to stock but it is suggested to go from gargoyle → openwrt → stock firmware.

1. you could read about bootloader in general and about Das U-Boot in particular.

Forum member pepe2k made a modification of U-Boot 1.1.4 for Qualcomm Atheros SoCs based devices (the project is still being developed, so new devices and SoCs will be supported in the future). Up to date information, binary images and sources can be found on official GitHub repository.

This modification started from wr703n-uboot-with-web-failsafe project, but supports more devices, all modern web browsers, has a lot of improvements and other modifications (like U-Boot NetConsole, custom commands, overclocking possibilities etc.).

More information:

• Official repository on GitHub: U-Boot 1.1.4 modification for routers
• Discussion about this project on OpenWrt forum
• An article (in Polish) about one of the first version of this project on www.tech-blog.pl

The task was to make ext-root without using the default ports.

It turns out that the GL850G chipset used by the TP-Link in WDR3600/4300/4900 models can handle up to four ports.

Analysing the router's PCB it appears that pins 8(D-), 9(D+), 11(D-) and 12(D+) are unused. Aditionaly each factory USB port has separate power section.

GND is at the TP7 pin point. +5 V was taken directly from the MOSFET.
