I’ve had LMDE6 installed since it’s release day and everything has been fine. For the past week it’s been dropping my wifi card randomly. It is not recognized by rfkill nor lspci after it happens. Only reboot helps.
Does anyone know why it might happen? Kernel is 6.1.0-21-amd64 but I don’t know has the kernel been updated recently.
Let me guess, Realtek
Edit:
What chipset?
I had some hard to track down intermittent network issues when I upgraded from LMDE5 to LMDE6 - the solution was to get a newer kernel from backports - its fairly painless…
I’d start with checking logs with journalctl as a privileged user. If the device disappears, there should be logs about it. Maybe that will point the way.
This. Sounds similar to a problem I had on my Intel chip (AX210) though I found out iwlwifi was panicking using dmesg. Probably would’ve been easier to use journalctl.
Which brand is it? I have an HP and have a similar problem, adding “pcie_aspm.policy=performance” to the kernel parameters mostly mitigates it but on Fedora like distros it may still have errors I don’t know how to fix.
Your computer is going into s1 and the driver for your card can’t wake it back up.
No. It goes off when I’m using it actively. I’ve never had any issues getting back from hibernate.
Damn, I thought I had you clocked.
Getting hot maybe? Some of those baseband chips are downright tiny and can’t really dissipate the heat they build up under heavy use…
Did you look at dmesg/journalctl to to see what the kernel says when it falls over?
E: spelling/autocorrect
How recent is your computer? Debian based distros, due to their focus on stability tend to have quite old packages, namely kernels
OP said it’s been running fine until recently, so I doubt it’s the kernel.
Kernel is 6.1.0-21-amd64 but I don’t know has the kernel been updated recently.
zgrep linux-image /var/log/dpkg.log*can tell you more.
