openwrt on wndr4300

So I want to install OpenWrt on Netgear WNDR4300.

Currently, stable release is 18.06.1 which is merged with LEDE.

After days of trial, I stick to 17.01.4 which can run ssr and other cool packages.

1 Prep

If the device can run a shell, gather device info by these commands. 

1
2
3
ssh user@router.ip
uname -a
cat /proc/cpuinfo

2 Image Release

It's recommanded to read start guide first, then download the appropriate image file.

First-time installation on a device, or flashing openwrt firmware, choose the factory install wndr4300 image.1 

1
2
3
tftp 192.168.1.1
binary
put lede-17.01.4-ar71xx-nand-wndr4300-ubi-factory.img

Sysupgrading an existing openwrt device on it's web admin GUI, choose wndr4300 system upgrade file. Compileing package with corresponding openwrt device's SDK file, choose ar71xx SDK.

3 Signal Strength

  • Choose Country as US, which has unlimited Transmit Power.
  • Operating frequency is another key parameter, relay radio will inherit the BSSID's mode, channel and width.
  • Frequency Width may halve and will cause channel's Bitrate halving too.
  • 2.4GHz – 20/40MHz, 5GHz – 20/40/80MHz

4 Packages

On openwrt 18.06.1, wndr4300 only has 13.71MB space to install packages, on LEDE 17.01.4, only has 13.9MB space.
