Hey,
I have no Internet through WLAN connection if my fedora starts new.
sudo systemctl restart NetworkManager
fixes this, but only until I start the system again, then I have to repeat the process.
Here someone suggests to
remove and reinstall your kernel WiFi Device driver
through:
sudo modprobe -r iwlwifi && sudo modprobe iwlwifi
at my device I end up at:
modprobe: FATAL: Module iwlwifi is in use.
Someone knows what to do to fix this? thx!
What do you see in the system logs related to wifi (journalctl -b -g wifi) before restarting NetworkManager, when you do it, and later?
thx 4 the quick reply!
before:
journalctl -b -g wifi

Make sure this is not a DNS related problem:
tracepath -n 8.8.8.8
tracepath -n 2001:4860:4860::8888
Also try collecting a more detailed log:
journalctl --no-pager -b -u NetworkManager.service
You can post the output to paste.centos.org.
sudo systemctl restart NetworkManager

Let’s isolate issues related to power saving, MAC address randomization and DNS.
Also modify the connection settings to use a custom DNS provider:
nmcli connection show
nmcli connection modify CONNECTION \
ipv4.ignore-auto-dns yes \
ipv6.ignore-auto-dns yes \
ipv4.dns 8.8.8.8,8.8.4.4
thx again
/etc/NetworkManager/conf.d/
is empty
I applied
nmcli connection show
nmcli connection modify CONNECTION \
ipv4.ignore-auto-dns yes \
ipv6.ignore-auto-dns yes \
ipv4.dns 8.8.8.8,8.8.4.4
I replaced “CONNECTION” by the name of the WIFI that the trouble appears with. After a restart the problem still occurs.
When the linked code is pasted to the terminal, it should create the config files in the specified location and restart the service to apply the changes.
Yeah you were right, the files were created. But unfortunately it did not fix the problem.
Can you check connection to any other wireless network?
Perhaps the issue is related to a specific combination of Wi-Fi settings, e.g. 2.4GHz / 5GHz, or open / hidden SSID, or WPA2 / WPA3 PSK, or TKIP / CCMP ciphers, or WMM / roaming mode, etc.
When I restart and try to connect to the hotspot of my smartphone it occurs as well and I remember being in another place using wifi that before worked without issues I had to run sudo systemctl restart NetworkManager as well to fix it.
I check the infos u gave from what is saved in my notebook and on my router:
| device | 2.4 GHz / 5GHz | open / hidden SSID | WPA2 / WPA3 PSK | TKIP / CCMP | WMM / Roaming |
|---|---|---|---|---|---|
| router | 2,4 GHz & 5GHz | open | WPA2 | CMPP (according to the router) | WMM (says the router) |
| smartphone | 2,4 GHz & 5 GHz | open | WPA2 | where to find? | where to find? |
I just witnessed, that after a restart that follows a system update, the Internet is detected fine. No sudo systemctl restart NetworkManager necessary. If I then just restart again, the Internet is not detected and sudo systemctl restart NetworkManager is necessary to get it back.
