@hansome i have a similar issue wih a AR150-EXT. I don’t believe its bricked but i do have jumper cables to flash the bios chip. I can’t connect to the device any other way as far as I know. The LED lights do turn on. Unless there is a way to flash it using the USB port but I’m not sure how to do that. I’m using Fedora and when I connect them via USB I don’t detect the device. Is there a driver I need? This happened when I tried to flash a custom firmware .bin while connected http://192.168.8.1 but then the SSID wasn’t visible and I was no longer connected. I tried to hold the reset for the 3 and 10 second time periods and still nothing.
