iwn not working Thinkpad T420

[dvogit]

I just installed FreeBSD 12.1-RELEASE on a T420; during installation it did not find any Wi-Fi Networks, even though there were over 10. I do not have ethernet.

I did follow the instructions in the Handbook for wireless networking, but I did not have working DHCP.

I first entered the Network Info in /etc/wpa_supplicant.conf with no success.

I did the configuration in /etc/rc.conf and it almost worked. But it reported: psk: bad value in dmesg

Here is the configuration:
ifconfig_wlan0=“WPA inet <ip> netmask <netmask> ssid ‘<ssid>’ psk ‘<password>’”

Isn't the wireless switch on the right side turned off?

I did the configuration in /etc/rc.conf and it almost worked. But it reported: psk: bad value in dmesg Here is the configuration:
ifconfig_wlan0=“WPA inet <ip> netmask <netmask> ssid ‘<ssid>’ psk ‘<password>’”

That configuration belongs into wpa_supplicant.conf(5)? In rc.conf(5), you want

wlans_iwn0="wlan0"
ifconfig_wlan0="defaultif inet <ip> netmask <netmask>"
create_args_wlan0="WPA regdomain ETSI country DE anywhere roaming manual powersave"

(you can omit defaultif) and /etc/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant
eapol_version=2
ap_scan=1
fast_reauth=1
country=DE

network={
ssid="xyz"
scan_ssid=1
psk="very_secret_pw"
priority=5
}

I guess /etc/rc.d/netif & companion /etc/network.subr do not understand WLAN special options in a standard ifconfig(8) command line.

Is the driver loader? iwn()

WiFi works according to FreeBSD Wiki: Laptops

I fixed it, the WiFi did not use PSK. It used EAN for security
