I tried to install unofficial (due to various drivers, in particular
the Intel WiFi network driver) Debian bullseye. During the
installation, I was asked for the network card, and I chose a wireless
one: wlp179s0, which is in my case WLAN/Bluetooth Adapter PCIe (WL-PCI
ASUS PCE-AX3000 BT5.0) Dual-Band (2,4 GHz/5 GHz), Bluetooth-Version
5.0.
Over the course of the installation process, did you get any messages
regarding missing firmware? I'm not sure this would explain the issue
you're describing, but that's an easy item to check for…
I was asked for the WLAN ID, which I provided (the SSID of my router).
Then I was asked for the type, which I provided as WPA/WPA2 PSK in my
case (WPA2 for my router). Then I was asked for the WPA-Passphrase,
which I typed in (WPA2 password for my router). Then a progress bar
depicting an authentication attempt with the access point appeared.
For a few minutes the bar continuously made progress (the messages on
the fourth console are attached) and finally reached 100%. Then I saw
a failure message asking me to verify the WPA-parameters which I
input.
I repeated the process several times, with the same result: no network
during installation. The wireless card itself and the SSID-password
combination are o.k. because I got connection using Debian live from
the same installation drive. (Moreover, on a similar machine with the
same network card the nerwork happily starts with NetworkManager,
though with ifupdown there is a delay of several minutes at boot; cf.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=993826). Any
bugfix? Any help?
The live test is quite useful, thanks for mentioning it. I'm wondering
whether this could be due to missing crypto modules inside our image,
which I've seen to be the reason for failure to associate from the
installer, while the installed system was fine. Any chance you could
start the live image again, save the output of `lsmod`, and attach it
here, using reply-all?
