This was eventually going to be a repository of my personal LEDE builds for the FS-WR106.
The file FS-WR106-stock-wrt-1505.zip is a stock OpenWRT Chaos Carrier 15.05 build from the manufacturer. They have not offered patches against stock 15.05 to date.
The stock firmware blob above is based on the OpenWRT WG3526 firmware build, but it holds the MAC address in another location.
The file -lede-ramips-mt7621-zbt-we1326-squashfs-sysupgrade.bin- is my build from LEDE master (r4188-e96a9a9af8) on 2017-05-25, with custom target, LuCI-ssl, and a few other changes inspired by @hnyman's WNDR builds. DO NOT USE THIS
openwrt-ramips-mt7621-zbt-we1326-squashfs-sysupgrade.bin will probably require you to delete your pre-defined wireless configurations, but wired should work just fine without reset. Please note that it has recent mt76 work done, but is still based upon kernel 4.1.x, so the SD card support is pretty worthless - but I never use that, so..
*If wireless doesn't work:
rm -f /etc/config/wireless
wifi config
for USB see https://openwrt.org/docs/user-guide/usb-drives

Update: 3/2019: This works natively with OpenWRT; use either the WG3526 build depending on your flash, or the WE1326 build, which mine is currently using: https://openwrt.org/toh/hwdata/zbt/zbt_we1326
This is primarily just leftover if anyone wants the old 15.05 build which was completely stable with the proprietary mt76 driver.
