On my XPS 9370 the problem was only reproductible on 1 type of wireless
access point and only when the network SSID was set to use both the
2.4Ghz and 5Ghz bands.
Configuring the access point to have different SSID for the 2.4Ghz and
5Ghz WIFI bands solved the issue.

Same problem for me. Dell XPS 13 9380 ubuntu edition.
Happens at least once a day, sometimes more often. Seems to happen more when
the network load is not high.
I've upgraded to the latest firmware, but without improvement.

I think the firmware is the same, so only the board-2.bin file needs to
be copied.
I am still seeing the issue with new board-2.bin.

Using the firmware from Comment #5 above stopped the wireless and my my
Bluetooth mouse from working, so I have reverted it to the standard
Ubuntu version.
sudo lspci -vvv -s 02:00.0 gives:
02:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network
Adapter (rev 32)
According to [1], new firmware can fix the issue.

Correct. Since I have been using Deep instead of S2Idle I have seen the
issue less -- though it has only been a couple of days as I was not
using this machine over the holidays. Even when it does break, Deep
suspending and resuming the machine brings the wireless back up and
working.

Do you mean the issue happen less frequently when using S3 instead of
S2Idle? I thought this should be the other way around.

Normally (maybe always?) it is when the network is idle. Thanks.
