 +**WARNING:** At least some of these routers seem to have unstable wifi in 12.09. They're hit by bugs [[https://dev.openwrt.org/ticket/12372|12372]] and [[https://dev.openwrt.org/ticket/13966|13966]].
 +
 +**NOTE:** The ethernet switch in this device, AR8327N, is working fine with the OpenWRT default configuration. But some of the more advanced functions of the switch are is not yet fully supported by the driver in 12.09. Most notably, a port cannot be tagged in some VLAN's and untagged in another, see [[https://dev.openwrt.org/ticket/12181|Bug 12181]]. A patch exists, but is not yet included in Trunk due to compatibility issues with older hardware.

 +
 +==== Flashing via TFTP =====
 +
 +Pressing the WPS/Reset button during powerup makes the bootstrap loader enter the TFTP recovery mode. The procedure can be used to transfer a firmware image:
 +  - assign 192.168.0.66 to your local network interface (the router uses 192.168.0.86)
 +  - publish a firmware image via tftp: ''cp openwrt-ar71xx-generic-tl-wdr4300-v1-squashfs-factory.bin /srv/tftp/wdr4300v1_tp_recovery.bin''
 +  - configure your tftp server
 +  - wait for the firmware transfer and subsequent reboot

 +(prior to actual flashing given availability of a serial console it's a nice idea to do dry runs, by ad-hoc RAM booting a factory.bin from a TFTP host server, via uboot "tftp" + "bootm", served via WDR3600's default 6F01A8C0.img filename).

 +
 +=== mtd-utils ===
 +
 +For systems where OpenWrt mtd is not available, mtd-utils commands need to be used (subsequent commands boldly assume that it's mtd5 which equals the "firmware" mtd partition name - cat /proc/mtd to verify!!):
 +<code>
 +flash_eraseall /dev/mtd5
 +nandwrite /dev/mtd5 /tmp/openwrt-ar71xx-generic-tl-wdr4300-v1-squashfs-factory.bin
 +</code>
 +(write operation will take about 5 minutes to complete)
 +
 +Note that output of newer mtd-utils flash_eraseall recommends using "flash_erase <dev> 0 0" instead (did not test it).

When the 'SYS' light (asterisk symbol right of the power light) starts to blink, immediately push the WPS/Reset button on the back-left of the router for a short time (>1 sec).

 +On a TL-WDR4300 Ver 1.6 and Barrier Breaker Bleeding Edge, r39211, the above instructions were not terribly successful. The only way that I was able to get the router into failsafe mode was to quickly and repeatedly press the WPS/Reset button //starting before the front panel "star" LED started flashing. //When that LED finally lit, it appeared to go directly into the rapid-flashing "failsafe" indication. If the WPS LED lights (rightmost, "yin-yang arrows"), it may be that you started clicking the button a little early in the boot sequence.

 +The latest stock firware (3.13.33(130617)) features a TFTP recovery client in bootloader. To activate it press and hold WPS/Reset Button during powering on until WPS LED turns on. Connect computer to LAN1. Using TCPdump, you should see ARP requests from router having address 192.168.0.86 looking for address 192.168.0.66.

 +
 +<code>
 +# ip addr add dev eth0 192.168.0.66/24
 +</code>
 +
 +Using TCPdump, you should now see request for new firmware image:

 +# atftpd --no-fork --daemon .</code>
 +
 +After downloading, the flashing starts immediately. After cca. 1 minute, the router reboots automatically.

 +
 +The default network configuration is:
 +^ Interface Name ^ Description ^ Default configuration ^
 +| br-lan | LAN & WiFi | 192.168.1.1/24 |
 +| vlan0 (eth0.0) | LAN ports (1 to 4) | None |
 +| vlan1 (eth0.1) | WAN port | DHCP |
 +| ? | WiFi | Disabled |
 +
 +==== Switch Ports (for VLANs) ====
 +Numbers 2-5 are Ports 1-4 as labeled on the unit, number 1 is the Internet (WAN) on the unit, 0 is the internal connection to the router itself.
 +^ Port ^ Switch port ^
 +| CPU  | 0 |
 +| WAN  | 1 |
 +| LAN 1 | 2 |
 +| LAN 2 | 3 |
 +| LAN 3 | 4 |
 +| LAN 4 | 5 |
 +| (not used) | 6 |
 +
 +The switch ports may turn out to be not properly bridged in a default bootup config, causing connection failure.
 +In this case you need to setup /etc/config/network or do manual swconfig setup - see [[http://wiki.openwrt.org/toh/buffalo/wbmr-hp-g300h#wired.stations.cannot.ping.each.other]] and [[http://wiki.openwrt.org/doc/uci/network/switch]] for advice.

 +==== U-Boot 1.1.4 modification for routers ====
 +Forum member [[https://forum.openwrt.org/profile.php?id=72549|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 [[https://github.com/pepe2k/u-boot_mod|GitHub repository]].
 +
 +This modification started from [[http://code.google.com/p/wr703n-uboot-with-web-failsafe/|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.).

 +=== GPIO ===
 +-> [[doc:hardware:port.GPIO]]
 +The AR933x platform provides 30 GPIOs. Some of them are used by the router for status LEDs, buttons and other stuff. The table below shows the results of some investigation:
 +

 +To make the GPIOs available via sysfs, the required ones have to be exported to userspace, as it is explained on a page of the [[http://squidge.sourceforge.net/gpio/|Squidge-Project]]. Kernel modules occupying that resource need to be removed before (e.g. "leds-gpio" and "gpio-buttons"). In output-mode, voltage levels of the GPIOs were measured against GND, after the value 1 or 0 had been written to /sys/class/gpio/gpioX/value. In input-mode, the value of the file /sys/class/gpio/gpioX/value was read when the GPIO was floating (initial state), pulled to GND or pulled to Vcc.
 +
 +The 5GHz LED seems not to be controlled via GPIO.
 +
 +==== Hardware Modifications ====
 +
 +
 +
 +=== USB Modification ===
 +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.
 +
 +{{:media:gl850g.png|}}
 +
 +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.
