-Note: I've tested many trunk versions; ​the wireless is not workingSo, please DO NOT update your RT-N56U router untill the bug is fixed!!!+  * full support with the barrier breaker stable release [[https://​dev.openwrt.org/​milestone/​Barrier%20Breaker%2014.07]]
  
 +Wireless network seems to have bug if you want to run both interfaces at the same time, see https://​dev.openwrt.org/​ticket/​17659 . A workaround is:
 +  - Set the country code to a specific country on BOTH the 5 GHz radio AND the 2.4 GHz radio.
 +  -  Go to System > Startup, scroll down to Local Startup, add the line "sleep 2 && /​etc/​init.d/​network restart"​ before the line "exit 0", and click Submit.
 +  - Click System > Reboot > Perform reboot.
 +**Note:** latest trunk has this problem fixed. (tested r44618 and up)

 ===== Installation ===== ===== Installation =====
--[[doc:howto:generic.flashing|Installing OpenWrt]]+There are two ways to install OpenWrt. Over the WebUI and TFTP. 
 + 
 +== Download == 
 +Either (recommended if you want a stable system) download a stable version of Barrier Braker [[https://​downloads.openwrt.org/​barrier_breaker/​14.07/​ramips/​rt3883/​openwrt-ramips-rt3883-rt-n56u-squashfs-factory.bin|squashfs-factory.bin]] for the initial flash. Use a "[[https://​downloads.openwrt.org/​barrier_breaker/​14.07/​ramips/​rt3883/​openwrt-ramips-rt3883-rt-n56u-squashfs-factory.bin|sysupgrade]]"​ file for any future updates if already on openwrt. 
 + 
 +Or (recommended if you need a system with all the newest features and do not care if the system may break) download latest snapshot of Chaos Calmer [[https://downloads.openwrt.org/​snapshots/​trunk/​ramips/​rt3883/​openwrt-ramips-rt3883-rt-n56u-squashfs-factory.bin|squashfs-factory.bin]] for the initial flash. Use a "​[[https://​downloads.openwrt.org/​snapshots/​trunk/​ramips/​rt3883/​openwrt-ramips-rt3883-rt-n56u-squashfs-sysupgrade.bin|sysupgrade]]"​ file for any future updates if already on openwrt. 
 + 
 +**Warning**:​ Do NOT flash snapshot image of Chaos Calmer for initial flashing as nothing is ON in snapshot image. This means unless you have a serial connected you will not be able to access the router. You can, however, easily update from a stable release to a daily snapshot, but make sure "Keep Settings"​ checkbox is checked. 
 + 
 +Alternative trunk builds (by moonman) with Luci included. Compiled with //​-march=74kc//​ instread of //-mips32r -mtune=74kc//:​ https://​olegtown.pw/​openwrt/​ 
 +As trunk advances some packages become broken and don't build. Be sure to check "​broken_packages"​ directory to make sure a particular build is not missing packages that you need.
  
-Use build root (selecting the RT-N56U configs ​in make menuconfig) to build your image. +== Install via WebUI == 
-Then flash the device with the (windows program that comes with the hardware). +  * Log in your routers admin interface 
-//The original web gui will not let you install any image.//+  * Administration -> Firmware Upgrade -> Choose **openwrt-ramips-rt3883-rt-n56u-squashfs-factory.bin**.
  
 +== Install via TFTP ==
 +  * Unplug router power cord
 +  * keep reset button down
 +  * plug the power cord back 
 +  * release the reset button.
 +  * led blinks slowly when ready for flashing
 +  * Assign your PC 192.168.1.11/​24 on eth0
 +  * tftp 192.168.1.1
 +  * tftp> bin
 +  * tftp> put openwrt-ramips-rt3883-rt-n56u-squashfs-factory.bin
