Hi,
I have new Nvidia Jetson Nano board with Intel wireless 8265/8275 onboard, but the wifi is really, really bad - the power of detected signal is very low and the connection breaks off all the time. I need to use nano as an onboard computer for a small robotic system, but for now the only possibilty to work remotly is by using ethernet cable (so that’ s not the most flexible option).
I checked if the card is detected by using
lshw -C network

Then, I did, because all forums say it can be du to power:
sudo iw dev wlan0 set power_save off
iw dev wlan0 get power_save off
Power save: off
(but after restarting I had to do it again)
It’s not router since I checked two of them already and the hotspot from my phone. The wifi works pretty nice on my laptop and my phone.
What else can I do?
PS I’m using micro-usb as power supply (i thought maybe the powers it too low, but i would be weird, right?).
