I’m experiencing a weird issue where my wifi connection randomly drops out.
It has been stable since october, but has start to occur after installing updates about a week ago. I dual boot and no issues in windows, and also i use ethernet (for synergy) to a windows laptop next to me which doesn’t drop out. Looking at the journalctl, seems to get stuck trying to authenticate a bunch of times, then suddenly works again. I’ve tried disabling the old powersave, but this hasn’t resolved it (/etc/NetworkManager/conf.d/wifi-powersave-off.conf).
journal:
wlp9s0: SME: Trying to authenticate with…
kernel: wlp9s0: disconnect from AP for new auth to…
…
[1740415872.3217] device (wlp9s0): Activation: failed for connection
Failed to query location: Error resolving “api.beacondb.net”: Temporary failure in name resolution
Ended up reverting to a kernel where i know it was ok. Here’s my notes if any use:
## list installed kernels:
sudo grubby --info=ALL | grep "^kernel="
## set default kernel from list (dated when i know it was working):
sudo grubby --set-default /boot/vmlinuz-6.12.11-200.fc41.x86_64
## check default is correct.
sudo grubby --default-kernel
## reboot and check running kernel
uname -r
###
# by default, Fedora keeps latest 3 kernels, so when a new one comes down, lose the oldest.
# can increment this in 'sudo nano /etc/dnf/dnf.conf' and set installonly_limit=5
# or lock a good version...
## lock the kernel so it doesn't get removed till a newer one is good
sudo dnf versionlock add kernel-6.12.11-200.fc41.x86_64
## list my locked kernels
sudo dnf versionlock list
## remove kernel when not needed anymore...
sudo dnf versionlock delete kernel-6.12.11-200.fc41.x86_64
