No. I tried it on a 4.13 kernel and the problem persists. Specifically,
1. I ping my router, everything is fine.
2. I download a large file from an ssh server at my uni. The speed is very
fast, 7.5 MB/s
3. After a few seconds, the internet drops out without any warning and I can no
longer ping
Also I want to add that I have to click `Turn Off' wifi twice if that
helps.

Title:
Wifi randomly drops out
Status in linux
Public bug reported:
On Ubuntu 18.04.3 LTS with Qualcomm Atheros QCA6174 wireless card, internet
drops out, particularly when downloading at speeds ~1MB/s say via P2P torrent.
The wifi connection (at least reported by wicd) remains active, but I cannot
ping the router or access the internet.

I updated the firmware via the instructions here:

It didn't help. I looked at journalctl --follow and dmesg before and
after the connections drops when downloading the large file, and no

I don't know how to update the firmware, so I followed these
instructions using fwupdmgr (https://itsfoss.com/update-firmware-

The issue still occurs. dmesg attached.

It seems when I update *all* firmware, not just for my wifi card, the
issue seems to be fixed. Thanks!

Hi Alexandre,
Yes I manually installed the latest firmware from the link above.
Just extract the contents to /lib/firmware and override.
I also installed the latest kernel. (currently 5.8:
https://kernel.ubuntu.com/~kernel-ppa/mainline/)

Hi Alexandre,
Try it! But download the linux-firmware.deb package in case it doesn't
work, Then you can just re-install the older firmware.

Public bug reported:
I'm using Lubuntu 20.04 on Dell XPS 13 9360. Somehow thunderbolt stopped
working. I've attached the relevant output from /var/syslog. I'm using
5.4.0-52-generic. I've updated all my firmware through fwupdmgr.
Briefly, the kernel complains

Sorry I realised my thunderbolt dock probably broke. Stupid dell thing
is low quality.

I also have this message. I use a Dell XPS 9360 with Lubuntu 22.04. Here
is my dmesg (note that I don't get any acpi warnings afterwards):

The CONFIG_EISA and related flags only affect compilation. They will not
affect an already compiled kernel. @Bram: how did you apply the kernel
parameters? I tried using the bootconfig tool, compiling it from the
ubuntu-kernel source, but they do not seem to loaded when I try cat
/proc/bootconfig.
If there is an issue with power management, the only other thing I can
think of is to disable power management in PCIe.
If you pass the kernel parameters pcie_aspm=off and pcie_port_pm=off I
think this would achieve this.
In your output of `sudo lshw -C Network`, there is “capabilities: pm”,

Why not try a 19.10 livecd?
Or you could try get the old firmware from the linux firmware git and
use a 4.x kernel and see if the problem disappears.
