Dear All,
as a follow-up please be informed that the issue is resolved by changing
to another cable router. My laptop connects without issues to my new
Vodafone Station (Arris TG3442DE) which I received as replacement for
the Connect-Box.
Kind regards,
Claudio

Dear All, Dear Will,
(Will, I copy you as I learned from one of your E-Mails that you own a
Dell XPS 13. Do you have issues with 5 GHz?)
Issue: WiFi freezes roughly every 5 to 30 min in Fedora 31. It is
stable in Windows 10 (Dual-Boot). Clicking on the WiFi-Network in
Gnome Settings restores the connection. After waiting for ~5 min the
connection re-establishes itself. After disabling 5 GHz in the
Connect-Box (my Cable Router) the connection is stable in Fedora 31.
How reproducible: Always, however the time until WiFi-freeze varies.
Having other devices located close seem to make the connection less
stable.
Actual Result: WiFi is stable on 2.4 GHz band and unstable on 5 GHz band
Expected Result: WiFi is stable on 2.4 GHz and 5 GHz bands
Steps to Reproduce: Surf the web using Firefox. When the connection
freezes, the WiFi Icon in the top right corner remains the same and
changes to a question mark after some time. After 5 min the connection
re-establishes.
Workaround: Assign separate SSIDs for 2.4 GHz and 5 GHz bands and
connect the laptop to the 2.4 GHz SSID. When connected to the 5 GHz
SSID the connection drops again.
Hardware: Dell XPS 13 (9380) with Killer Wireless-AC 1435
OS: Fedora 31 Dual-Boot with Windows 10. The laptop came pre-installed
with Windows 10.
Driver: firmware-6.bin_WLAN.RM.4.4.1-00140-QCARMSWPZ-1 (Fedora Offical
Repo) or firmware-6.bin_WLAN.RM.4.4.1.c3-00059 (github.com/kvalo)
Regdomain: I live in Germany, country code "DE". The EEPROM is not
adjusting to "DE" when connected to my Cable Router, but adjusts to
"DE" if connected to my phone hotspot.
Cable Router: Compal Connect-Box (Liberty Global, UPC, Unitymedia,
Software-Version: CH7465LG-NCIP-6.12.18.25-2p6-NOSH). Same SSID
assigned to 2.4 GHz and 5 GHz band, WPA2, autochannel, channel
optimization is on (and cannot be disabled). In thread [1] two users
report similar issues with Virgin Media Hub 3.0, which seems to be
same router as my Connect-Box [2], [3].
Is this a (known) bug in ath10k or is my Cable Router the culprit?
Note that it works under Windows 10 with 5 GHz. Any help, e.g. how to
get better logs to assign the cause to the cable router is appreciated
as I can contact my ISP with this information and hopefully get a
firmware update for the router one day (or a new router). I am aware
of thread [4], but from my logs I cannot see anything hinting into the
direction that NetworkManager or Power Saving is the cause.
Thank you and kind regards / happy holidays,
Claudio

Note to the logs: I noticed that WiFi did not work at 22:20 h.
Connection re-established itself roughly at 22:25 h. All logs copied
at 22:27 h. Afterwards WiFi remained active until 22:48 h, then
stopped again.
