How to config WiFi on ThinkPad T530?

[smartly]

I install all driver and tools.

example:

Code: Select all

apt update
apt install firmware-iwlwifi wpasupplicant

Has been able to scan to WiFi hotspot, like:

Code: Select all

# ifconfig wlan0 create wlandev iwn0
# ifconfig wlan0 up scan
SSID/MESH ID    BSSID                     CHAN RATE   S:N        INT CAPS
dlinkap          00:13:46:49:41:76   11   54M -90:96   100 EPS  WPA WME
freebsdap          00:11:95:c3:0d:ac    1   54M -83:96   100 EPS  WPA

I create wpa config /etc/wpa_supplicant/wpa_supplicant.conf:

Code: Select all

ctrl_interface=/var/run/wpa_supplicant
network={
        ssid="SSID"
        psk="PASSWORD"
}

Try link to my AP:

Code: Select all

# wpa_supplicant -i wlan0 -D bsd -c /etc/wpa_supplicant/wpa_supplicant.conf

But it's failed.
I install kfreebsd 10.3 kernel

If the kfreebsd configuration is the same as the linux configuration, try this.

Do not configure wpa_supplicant.conf, but configure /etc/network/interfaces or /etc/network/interfaces.d with the stanza:

Code: Select all

# Wifi
auto wlan0
iface wlan0 inet dhcp
    wpa-essid ESSID
    wpa-psk SHAREDKEY

Substitute the name of your wifi device for "wlan0", your ssid for "ESSID", and the wpa private shared key (NOT passphrase) for "SHAREDKEY".

Use the wpa_passphrase utility to generate the SHAREDKEY from your ssid name and passphrase. Generally:

Code: Select all

wpa_passphrase  ESSID PASSPHRASE

with appropriate substitutions for "ESSID" and "PASSPHRASE".

The wpa_supplicant daemon is implied by the interfaces configuration and automatically started. This is tested on my T530 with jessie and the linux kernel. YMMV with kfreebsd.
