WiFi crashes and I can only reboot to fix

viniosity · 2019-03-14 19:19:42

I have an HP Envy x360 13" laptop that works very well on Arch Linux except sometimes the wifi stop working and I can't get it back running. I've been on different Network Managers and this problem also happened on Ubuntu after kernel 4.19.1 sometime. To be clear, I have tried restarting my NetworkManager and that doesn't work.

I looked at dmesg but if I should be searching another log, please let me know. This is one of my biggest problems and what's tempting me to move back to a Mac or Chromebook.

It's a laptop issue but I think it's kernel related so I'm posting it here. Mods, please feel free to move it if you'd prefer it elsewhere. Thanks in advance.

Hello your wifi is certainly managed by a kernel module (mac80211 ?)
Have you tried to rmmod it and insmod or modprobe it again?

V1del · 2019-03-17 12:43:45

Please use [ code ] tags not quote tags for pasting output. And please post more of that dmesg/journal (the entire thing would be best) as the excerpt you provided is likely to only be a follow up crash to the actual problem, which is happening earlier.

Trilby · 2019-03-17 13:19:03

And what are the actual symptoms? When the wifi "crashes" disabled all networking services and try to connect manually. What step fails and with what error message?

viniosity · 2019-03-17 14:38:02

Sorry, @V1del - I updated it to use code blocks. I have more of the dmesg trace but it seemed repetitive. Perhaps I cut that trace too soon. I'll grab more next time it crashes.
@ivanoffI, I have not tried this but I will next time it happens - thanks for the tip!
@Trilby, one second the network is there the next wifi is gone. Pings say "Network is unreachable". My wifi scanner shows no networks. If I stop NetworkManager and start an alternative like netctl, then wifi-menu similarly fails to find any networks. Restarting the laptop brings it back up.

I will try the rmmod trick next time it happens and also post a longer trace.

Thank you, everyone.

Go. Through. The. Steps.

For example, does the interface still show up in `ip` output? Is it up?

Could be power saving, also there's https://bugzilla.kernel.org/show_bug.cgi?id=91171
Post a complete journal ("sudo journalctl -b") covering the issue (you can eg. dump a former boot, like "… -b -1") and "iwconfig wlo1"

iw dev wlo1 set power_save off

would disable power saving but that's pointless if this isn't the cause (The last comment in bug #91171 mentions WOL triggering this)

--------
Edit: Oh, and please outputs of lsusb/lspci before and after this happens and "rfkill" after it happened
--------

@ivanoff, mac80211 is the IEEE 802.11 subsystem, not a specific device driver.
