Frequent wifi disconnection

[blogdemoi]

Hello,

Due to my poor wifi at home, my Birdnet-Pi sometimes disconnects from my wifi (e.g I have to relaunch my router which is another raspberry pi) and it doesn't auto reconnect to the wifi. Do you know any method to make my Birdnet-pi auto reconnects to the wifi network when this happens? Currently I can only hard reboot the Birdnet-Pi unplugging from power socket, which is bad.

Thank you.

Woah...that's really weird. Mine reconnects to the Wifi if I happen to power-cycle (accidentally unplug) the wifi. Is there anything special about your Wifi setup on the Pi? Did you hard-code any extras?

Whilst that might be a stop-gap solution, there has to be a reason that it keeps disconnecting. It's very weird.
So rebooting the birdnetpi doesn't work, you have to physically power it down?

Yes, I can't even ssh into.

Hmm...okay, I'd be putting a monitor and keyboard on it to see what state things are in when it drops out.
Anyway, try the power management thing, who knows.
FYI, mine has power management still turned on and it reconnects fine but it's certainly worth a try.

oh ok, this has been marked as answered. Sorry. As you were.

Thank you for trying to help me. I will try first mcguirepr89 solution, then the cron solution then the RJ45 cable... Now I wait for the next disconnection.

wlan0 on a Raspberry Pi has power management automatically turned on. I would recommend disabling this on boot to address your issue.

Just above exit 0 in /etc/rc.local, add this line:

iwconfig wlan0 power off

and that will disable power management (the thing that cuts the power to your wireless network card after it loses the connection to your WiFi, preventing it from reconnecting in the future).

Thank you, I will try this first.
