WiFi Issues under 25.10: Cannot connect to new WiFi Networks
I had installed Kubuntu in my home WiFi network (which works fine) but struggle with new networks. After choosing the network and entering the PW it seems to immediately "forget" it and prompts me to enter it again. PWs were always triple checked 😉 and WPA... settings were taken from other mobile devices. Does anybody have a solution...I tried to find some help in the www and tortured my AI with the problem. In the end I asked LeChat to summarise the issue (new to Linux):
Problem:
The WLAN interface wlp194s0 cannot be activated correctly, even though the configuration is correct. This is because NetworkManager cannot find the interface or the driver is not functioning properly.
Hardware:
- WLAN Interface:
wlp194s0 - Driver:
mt7925e(Mediatek) - NetworkManager is used to manage network connections.
Solution Attempts:
- **Check the status of the WLAN interface:**bash Copy
nmcli device status- The interface
wlp194s0is in adisconnectedstate.
- The interface
- **Manually activate the interface:**bash Copy
nmcli device connect wlp194s0- This command fails with the error: "Connection activation failed: The Wi-Fi network could not be found."
- **Check the connection:**bash Copy
ping8.8.8.8- The ping command works, indicating that the wired connection is functional. (NOTE: I was tethering trough my mobile via USB!!)
- **Check the driver status:**bash Copy
lspci -knn | grep -A3 -i "network\|wireless"- The WLAN adapter is identified, and the driver
mt7925eis loaded.
- The WLAN adapter is identified, and the driver
- **Install missing drivers (if necessary):**bash Copy
sudo apt install firmware-misc-nonfree- This package is not available, so it cannot be installed.
- **Reload the driver:**bash Copysudo modprobe -r mt7925e sudo modprobe mt7925e
- This step ensures the driver is properly loaded.
- **Check the logs:**bash Copy
journalctl -u NetworkManager -f- The logs show that the WLAN interface
wlp194s0is not being managed correctly by NetworkManager.
- The logs show that the WLAN interface
Conclusion:
The WLAN interface wlp194s0 is not being activated correctly due to issues with the NetworkManager or the driver mt7925e. Despite multiple attempts to reload the driver and manually activate the interface, the problem persists. The logs indicate that NetworkManager is unable to manage the interface properly, leading to the conclusion that there might be a deeper issue with the driver or the network configuration.
