So I just debricked my wireless router using serial connection and thought everything is OK but now I can't get any wireless signal even though interfaces are up. I tried putting my phone on the router itself and then I got a signal but if I move it just a bit the signal is lost... Router is Asus ac58u and I see the antenna connection are fine.
Is there a way to check if it's a lost cal_data or hardware issue? I read some threads about lost cal_data and most of them showed no data at all on the wireless interface while in my case it seems everything is working but range is 0 like antennas are not working.
So i found a backup of my cal_data and restored it but problem persists: wifi signal is 0 and can my phone sees it only when practically 1 inch from the router so i guess it is a hardware failure probably caused by connecting to the serial port on the router, maybe 3.3v wire fried something, so unfortunately router is bricked...
