rt-n56u-qos

ASUS RT-N56U/N65U/N14U custom firmware with QOS

Upstream: http://code.google.com/p/rt-n56u/
Prebuilt Images: https://www.mediafire.com/folder/z09g335s500o4/Padavan%27s_RTN56U_firmware_QOS_mod

========

Modifications:

  1. Added BFQ I/O scheduler
  2. Added OpenWRT QOS script for QOS into the firmware
  3. Added patch for newer systems with texinfo >= 5 to bootstrap cross-gcc 4.4.7
  4. Added gcc 4.7.3. All images are compiled with this now.
    Starting with *3.8-081-moonman-6 all builds are compiled with gcc 4.8.2 (with better optimizations for 74kc)
    Starting with *3.8-084-moonman-7 all builds are compiled with gcc 4.9.1 ** Beware: any version of gcc past 4.4.7 causes problems in builds, particularly native ipv6 does not work, and ** PPTPD does not accept connections. I've reverted back to 4.4.7 until these problems are resolved.
  5. All images are compiled with appropriate compiler optimizations instead of generic mips32r2:
    RT-N14U: -march=24kec -mtune=24kec
    RT-N56U/RT-N65U: -march=74kc -mtune=74kc

=========

How-To:

  1. If NOT coming from stock f/w, reset internal storage after flashing:
    Advanced Settings -> Administration -> Settings ->
    Router Internal Storage (/etc/storage) -> Reset
  2. Disable HW Nat:
    Advanced Settings -> WAN -> Hardware offload NAT/Routing IPv4 -> Disable
  3. SSH (or WinSCP) into the router and modify /etc/storage/qos.conf for your connection
  4. Change QOS_ENABLED variable in qos.conf to YES (all caps)

=========

To build:

  1. Follow the steps outlined here:
    http://code.google.com/p/rt-n56u/wiki/HowToMakeFirmware
  2. Additionaly install sudo if it isn't installed. (it isn't, by default, in Debian)

========

I use ArchLinux installation with debian sid chroot.

Install "debootstrap" from aur and create a chroot.
Place this script in <chrootdir>/bin and make it executable
(I called this script "start")

#!/bin/bash

PATH=$PATH:/bin:/sbin:/usr/sbin
export PATH

/bin/bash

to chroot use

arch-chroot <chrootdir> /bin/start
