Intermittent issues with Atheros QCA6174 on XPS 13 9380

I'm experiencing intermittent wifi issues with an Atheros QCA6174 on
an XPS 13 9380 notebook. I started pinging my AP and noticed that
ping times go from <10ms to >10,000ms when this happens.
64 bytes from 192.168.0.1: icmp_seq=1154 ttl=64 time=3.18 ms
64 bytes from 192.168.0.1: icmp_seq=1160 ttl=64 time=8572 ms
64 bytes from 192.168.0.1: icmp_seq=1161 ttl=64 time=7549 ms
64 bytes from 192.168.0.1: icmp_seq=1162 ttl=64 time=17518 ms
64 bytes from 192.168.0.1: icmp_seq=1163 ttl=64 time=16497 ms
64 bytes from 192.168.0.1: icmp_seq=1169 ttl=64 time=10412 ms
There's also huge package loss.
Various observations:
* There's no warning in dmesg when this happens.
* I'm only 1-2 meters from the AP and connection quality is good.
Other devices connected to the same AP don't have problems.
* rmmod & modprobe solves the issue, but only temporarily.
* I tried to set a lower speed with "iwconfig wlp2s0 rate 11M" but
that made no difference.
* This is with 2.412 GHz. My AP doesn't have 5 GHz
* The problem doesn't happen all the time. I haven't found a
clear pattern yet. However, watching videos on YouTube usually
(but not always) triggers it. (It also shows without YouTube,
but YouTube is a good way to trigger it.)
* When it happens, it happens every few minutes (without an obvious
pattern). Sometimes it goes back to normal quickly (less than a
minute) but sometimes it takes a long time and then I do 'rmmod'.
* I've tried with different kernels: 5.15, 5.14, 5.10 (all from
Debian) - all show this issue
* I downloaded the latest firmware from https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174/hw3.0/4.4.1
(WLAN.RM.4.4.1-00288)
This made no difference
* The mainboard of my laptop was swapped about two weeks ago. I don't
think I had this problem in the past (there were Internet issues from
time to time, and I assumed it's the broadband; but maybe it was a
wifi issue. It doesn't wasn't as bad as now though because I would
have noticed. Now wifi is pretty much unusuable, at least for
YouTube). The Atheros chip is the same brand, so not sure if the
mainboard switch matters. (But it's weird because I didn't have the
issues before.) I'm not sure about software changes in recent
times but I can't think of anything too obvious.
* I booted into Windows 10 and watched YouTube for two hours and
didn't notice the same problem there.
Is this a known issue? How can I provide more debugging info?
Below is some more info about my system. I've also attached some
ping logs.
