Note: With only @n-steph I had fever issues but still issues were present.

Title:
ath10k_pci:
This problem happens for me, with newest firmware, newest kernel, as of
today - but turns out only in the following situation:
- wireless router supports both 2.4 and 5 GHz
- same SSID name is used for both ranges
I.e. after disabling 5 GHz support on the router, the wifi card no longer
I have had some success (3 suspends now and not a crash) by using a
newer version of the firmware from upstream, specifically this version:

firmware/blob/master/QCA6174/hw3.0/4.4.1.c2/firmware-6.bin_RM.4.4.1.c2-00057-QCARMSWP-1
Download that, and replace the file
I am seeing this occur on 16.04 and that too only on my home network. I
am using a D-Link DIR-150M router. Hope this helps in solving this bug.

Just wanted to add a note here. I had noticed this only happened on my
home network, and nowhere else.
I had tried hard-setting the channels and bands but nothing affected it
on my Linksys WRT1200AC even with moving it around the house and using
extenders. At my co-working space I rarely had the

For those on Bionic and who recently met the trouble, try down-grading
linux-firmware to 1.73 from 1.73.1. Test.
I have a different wifi chipset and met problems wifi with the update solved by
the downgrading.
Of course, YMMV. If this helps, then a new bug report must be filed for each
chipset
I have never had problems wit heat or sleep, so I would see this issue
completely unrelated.
Also it did work for me, fine, for months in the past and I changed
nothing to the system.

I'd made precisely one change to the config on the XPS9370; which was to
add deep sleep to the kernel boot parameters for grub, vis.
```

I changed nothing on my wifi, so the issue must have been introduced by
some change in ubuntu.

I'm having still (06/2018, Ubuntu 18.04, latest linux-firmware) the
issue with the crashing ath10k_pci firmware, mostly after the laptop
goes to suspend mode.
My workaround currently is restarting it via:

sudo modprobe ath10k_pci

I face very similar problem, but I have v2.1 hardware of QCA6174 (I assume you

I installed Kubuntu Bionic Beaver (18.04) from fresh.

I tried what Wren tried, but this did not fix the problem for me. I

Before pulling in the new firmware, I tried the upstream kernel per the
wiki instructions I found in the Ubuntu wiki. The same problem existed
there. Now, I am running the artful kernel with the bionic firmware
files that I manually copied over as indicated above.
