Hacking DIR-818LW (with RTL8881AB) with openwrt

[Click to see all post about my openwrt hacking on DIR-818LW]

Today, I have got myself a D-Link DIR-818LW (rubbish bin looked alike) router, with hardware revision B1. According to the internal photos found on FCC and information found on wikidev, it uses RTL8881AB as its SoC (with Lexra RLX5281 CPU which also found here) which includes 802.11ac. Another chip onboard RTL8192ER have provided 802.11bgn 2T2R (there are two antennas for 11n and 1 antenna for ac), and RTL8367RB for Gigabit switch.

I was hoping to install openwrt on this router, as the original firmware does not provide wifi bridge/repeater functionallity. A bit of Google search found this, which got an openwrt image for RTL8881AB and RTL8367RB.

Also, there are source code for D-Link stock firmware too! (HUGE Thanks to GPL!)
Original Firmware (v2.05b1):
ftp://ftp.dlink.eu/Products/dir/dir-818lw/driver_software/DIR-818LW_REVB_FIRMWARE_PATCH_2.05.B01.ZIP

GPL source code (v2.03b1, older than the released firmware a bit):
https://dlink-gpl.s3.amazonaws.com/GPL1400446/DIR818LW_GPL203_Readme.txt (md5: 9535d6e47e9c955f97a8cc967d41f30f)
https://dlink-gpl.s3.amazonaws.com/GPL1400446/DIR818LW_GPL203b01.tar.gz (md5: 0c9714c9da99c9c535274423de8de678)

Note that Lexra toolchains were included into the GPL source code package!

Now, I am gonna explore the hardware and I will update more :)
