Dell XPS 9360 with QCA6174, 5GHz Connection drops after few minutes

I have a Dell XPS 9360 with Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter.

It have a archlinux installation dual booted with Windows

$❯ uname -a
Linux dark-space 5.4.75-1-lts #1 SMP Thu, 05 Nov 2020 12:39:20 +0000 x86_64 GNU/Linux

$❯ lspci -k
...
3a:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)
        Subsystem: Bigfoot Networks, Inc. Device 1535
        Kernel driver in use: ath10k_pci
        Kernel modules: ath10k_pci
...

The problem is I am able to connect to my 5Ghz connection but after few minutes it freezes up with no traffic.

$❯ iw dev wlp58s0 link

I am able to connect to my 2.4Ghz connection properly but not 5Ghz one.

But the same 5Ghz connection works properly in my windows.

I have also updated my firmware to latest version according to  https://wiki.archlinux.org/index.php/De … )#Wireless

dmesg | grep ath

But the issue is still not resolved.

No solution to propose but I have the same issue on my XPS 13 9370. 2.4GHz works OK and 2.4GHz & 5GHz work fine under Windows.
If anyone has any solution... What I can read all over the place is "get rid of the card and get an Intel one", but I think the network card is soldered to the motherboard ><

If I'm reading version numbers right then the one in linux-firmware is technically newer

5GHz works fine here, but it's a gigabyte board rather than whatever's in that dell.

If it might help here's some link info from iw
