I am a bit lost with this issue and hoping someone can maybe point me in some troubleshooting directions
Setup
Hardware: NovaCustoms NV41 with Coreboot
OS: Qubes 4.2.1 (installed as 4.2)
Network card: Intel AX-200/201 WiFi module
sys-firewall: Fedora 39 ( 6.6.25-1.qubes.fc37.x86_64)
sys-net: Fedora 39 (6.6.25-1.qubes.fc37.x86_64)
What’s happening
For nearly as long as I have had the laptop (3 months), random times throughout the day I will lose network access for anything from a few seconds to maybe a minute at a time before connection is restored during this time the laptop can not pass any network traffic. It will then just start working again on its own.
From what I have seen on the network in this time no other devices are experiencing this as other devices will work when the nv41 does not so I don’t believe it’s access point issue.
In the xfce panel the network manager shows that the wifi conenction is there and there’s a good signal strength.
None of the appVMs are able to make network connections e,g, browsing, ping (name or ip) , ssh, vpn connections
To what kind of network do you connect? How is/are your routers/switches configured?
Please post the output of
[user@sys-net ~]$ lspci -k
and
[user@sys-net ~]$ sudo dmesg
and
[user@sys-net ~]$ lsmod
Did you fiddle with any kind of powermanagement?
Hi @OvalZero
To what kind of network do you connect? How is/are your routers/switches configured?
Currently:
WiFi6 with WPA3 dlink (previously other hardware - WiFi5 and WPA2 to same results)
|
V
connected to router
|
V
connected to internet
As mentioned other devices connected to wifi work, and I can also connect out directly from the router
Did you fiddle with any kind of powermanagement?
no it was all stock, other than 2 days ago changing max charge via coreboot settings
Output of the 3 commands can be seen here
https://cryptpad.fr/code/#/2/code/view/uUeVLEn4i+UNTRMDIED4Py6w3frEfFU6I-c8K5J+jaI/
The dmesg looks to have caught around the time I had some problems and rebooted up until now

I’d try out and switch to the latest kernel image before tweaking kernel module params. (I’m sorry, I can’t test it for you. I got a different wifi chipset.)
Edit: Up until kernel 5.1x? (I’m not sure about the exact minor versions) there were problems connecting to 5GHz wifi with constant link resets.
I’ve had troubles with qubes at the beginning due to mac “cloaking” (i.e. arp spoofing) settings in nm. My switches (with LPS) didn’t like this, until i set permanent mac ids for known networks in nm on the laptop.

no need to be sorry. I understand this is likely to be a niche problem 
I’ll enable testing and give newer kernel a try
Thanks apparatus, this is also a good avenue to try
