Network with NetworkManager stop working randomly

Purgator · 2017-10-12 10:16:39

Hello i'm back again. I used to have small disconnections issues but just reconnecting to the AP usually solve the problem.

Today I got a big issue that made my WiFi totally down. If I use a wire it's ok. I will reboot to solve the issue.

Right now, I can bring this logs :

I have 2 terminals, the first one with the command «journalctl -f»
The second that launch commands.

nmcli r all off

Any idea on what's wrong here ?

Could not set interface wlp2s0 flags (UP): Input/output error

intel_iommu=off ? (basically the answer to all weird problems atm)

Purgator · 2017-10-12 13:08:38

How to check the state of iommu ?

Cause ATM :

dmesg|grep -i iommu

returns nothing.

Then it's not in use.

Notably test whether resetting the PCI controller works - NOTICE the different bus ID (yous is 0000:02:00.0)

https://bugzilla.kernel.org/show_bug.cgi?id=91171#c102 blames the WOL feature.
