Troubleshooting • Re: New router : change connection settings on a Headless RPi4B ?

Hi everyone !

I just moved, and due to a technical issue with my optic fiber connection, my internet provider is lending me a 4G Wifi-Router (ZTE U10e) for a while.

I have a headless RPi 4B that allows me to run Birdnet-Pi (https://github.com/Nachtzuster/BirdNET-Pi) and I view the results via a local web page.

Since the connection informations have changed, my RPi no longer manage to connect to the Wifi, and I can therefore no longer see the data it generates.

I tried modifying the wpa_supplicant.conf file by adding these parameters, but nothing works :

Code:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdevupdate_config=1country=FRnetwork={ssid="MySSID"psk="MyPassword"key_mgmt=WPA-PSKproto=RSNpairwise=CCMPgroup=CCMPauth_alg=OPEN}

Basically, the only thing I can do right now is take the microSD card from my RPi and put it in my computer to modify it manually.

Do you have any suggestions?

Thanks !

Jean
