Raspberry Pi 4 fails to establish a connection to Wi-Fi despite being linked via Ethernet.
You're experiencing connectivity issues with your Raspberry Pi 4b when trying to access the internet via wireless after connecting to Ethernet. The Wi-Fi indicator keeps showing a name, preventing a stable connection. Here are some possible solutions beyond reinstalling the OS:
- Check for firmware updates or patches that might resolve this issue.
- Ensure the Ethernet cable is securely connected and not damaged.
- Try resetting the network settings on the Pi (resetting Wi-Fi and DNS).
- Verify that your router supports the necessary protocols (like WPA3) and that it's not blocking the connection.
- Disable any firewall or security software temporarily to rule out interference.
- Update your Raspberry Pi OS to the latest version, which may fix underlying bugs.

Remove the wireless configuration from /etc/wpa_supplicant/wpa_supplicant.conf. Open the file with sudo nano and delete any lines that resemble network settings like the one shown. After editing, restart your device or run sudo service networking restart. You should now be able to set up Wi-Fi from the desktop.
