I have a Lenovo Ideapad 100S 14'' IBR-14'' Intel Celeron CPU N3060 @ 1.60GHz, 32GB SSD, 4GB RAM, but I am both at a loss what wifi I have there, as there are several different generations, and how to find which driver I have to use in FreeBSD.

How to go about it?


To find what kernel wifi the driver to use, do:

$sysctl net.wlan.devices 
net.wlan.devices: iwm0

So we know now we have to use iwm0.

You can also find the corresponding hardware doing:

$ pciconf -lv iwm0
iwm0@pci0:2:0:0:    class=0x028000 card=0x82708086 chip=0x08b48086 rev=0x93 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Wireless 3160'
    class      = network

So now we know it is a model with an Intel Wireless AC, and the iwm0; which are very good news, as this model was sold to me as capable of doing bgn, and not 802.11n AC.

While in the past the Intel 3160AC driver had to be compiled, nowadays, it is already supported by the default kernel.

Now to set it up, we will load the module, the firmware and the supported wifi authentication protocols in /etc/rc.conf:


Also in /etc/rc.conf, will define the wpa_supplicant, DHCP client, activate the interface and define the country as PT for it to transmit in a stronger frequency more appropriate for my country:

create_args_wlan0="country PT"

Now search for wpa_config and install it:

#pkg search wpa_config
wpa_gui-2.6                    Qt-based frontend for wpa_supplicant
wpa_supplicant-2.6             Supplicant (client) for WPA/802.1x protocols
#pkg install wpa_gui wpa_supplicant

Edit now /etc/wpa_supplicant.conf:



Upon restarting, you can see the lines, or later with dmesg.

iwm0: hw rev 0x160, fw ver 17.352738.0, address f4:06:69:xx:xx:xx
wlan0: Ethernet address: f4:06:69:xx:xx:xx
iwm0: iwm_update_edca: called
iwm0: iwm_update_edca: called
wlan0: link state changed to UP

We have now wifi connectivity, IP address and Internet connectivity.

$ ifconfig wlan0
wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    ether f4:06:69:xx:xx:xx
    inet netmask 0xffffff00 broadcast 
    media: IEEE 802.11 Wireless Ethernet OFDM/54Mbps mode 11g
    status: associated
    ssid xxxx channel 13 (2472 MHz 11g) bssid 30:b5:c2:xx:xx:xx

    scanvalid 60 protmode CTS wme roaming MANUAL
    groups: wlan 

Finally for configuring it graphically, you can use wpa_gui ; if using Lumina you can also install pcbsd-utils to have the wifi icon on the tray.

To list for the available SSIDs in the command line do:

#ifconfig wlan0 list scan
