Hi Stefan. Thanks for Your prompt response! Since I seem to understand firmware is taken from linux iwlwifi, my idea was to understand which one(s) you picked up and how you built the package iwx-firmware-20191022p0. Maybe worth trying with some other .ucode in there.. don't know, just guessing. I am not an expert
What do you mean by specific environment? It is a PCI-E card installed on my desktop. Yesterday I did a fresh snapshot of 6.7 installation and configured the card with WPA2. Even before configuring it and being able to connect to the network (stuttering) dmesg frequently printed that message related to "SCAN". I tried to measure the speed as soon as I got a desktop working, and it goes from some hundred to 800/900 Kbits per second. Probably this very slow rate has to do with unlucky firmware and continuous connection resets. Gmail is not able to load, for example. What is the speed you get? Is it stable? I wish I could help You more. Giacomo.
