I carelessly bought an Ubiquiti UniFi 6 Extender (also known as U6-Extender-EU - it has the Schuko plug, not the American Type-B).
I figured it worked like all other WiFi extenders I ever used (you plug it in - it turns on and gives you an open WiFi SSID - you connect to it, scan the waves and bridge it to the WiFi you want to extend - done) but it does not, it requires another Ubiquiti device to inherit its configuration from in what they call "wireless uplink".
My hopes to send it back and get a refund are getting slimmer and slimmer, so I'm looking if there is any chance to flash it with OpenWrt and use it in some capacity.
I logged in with the factory default configuration (reset the unit - you find an open SSID named as the MAC address on its label - you SSH to 192.168.1.20 with ubnt/ubnt as login/password) and I see that I can run some commands.
In the future, the MT7621 UniFi6 family can be supported by a single
config@1: U6 Lite
config@2: U6 IW
config@3: U6 Mesh
config@4: U6 Extender
config@5: U6 LR-EA (Early Access - GA is MT7622)
So, is there any chance to make this Ubiquiti U6 Extender work with OpenWrt?
