Hi there.
I am struggling with a rather annoying problem.

I decided to "dig up" an old minipc, a Dell OptiPlex 3040 micro and install FreeBSD on it.

uname -a
Code: 
FreeBSD crap 14.0-RELEASE-p3 FreeBSD 14.0-RELEASE-p3 #0: Mon Dec 11 04:56:01 UTC 2023     root@amd64-builder.daemonology.net:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64

I bought a TP-Link TL-WN821N USB dongle to avoid using a cable connection (Link to TP-Link spec).
I have read rtwn(4), rtwn_usb(4), looked through many threads here on the forum and got to this point....

I have wlan0 added, however I cannot connect to any network.
I tested connecting to the router (2.4GHz, password), I also created a hotspot on my phone (2.4GHz, no password)
I tried establishing a connection manually using wpa_cli, ifconfig, networkmgr and zero results.

Here is my coniguration (I tried different combinations, but on these settings there is at least some effect - created wlan0)

There is a problem with the creation of wlan0 during system startup.
Once I log in and remove and reinsert the card wlan0 is created.

Then when I call the command
ifconfig every few seconds I see that the system is scanning the networks stored in
/etc/wpa_supplicant.conf. The channel changes.
It connects to that one open network, but does not get an address and the status is always
Code: 
status: no carrier

Sorry for the haos in my post, but I can't very well describe my problem.

In short: I can't connect to any network.
