The
Intel Centrino Advanced-N 6205
WiFi adapter can be found also in the Lenovo X230 series. The laptop is well
supported by FreeBSD, and the iwn(4)
driver covers the WiFi
chipset, so connecting to a WiFi network should be no problem. Unfortunately,
the performance is rather poor, especially while using the 5 GHz channels.
It may help to disable IEEE 802.11n with:
# ifconfig wlan0 -ht
Otherwise, a Android-based mobile phone can be used to connect to a WiFi
network by USB tethering instead. Using an Android device requires to load the
urndis(4)
driver at first:
# kldload if_urndis
Add the kernel module to /etc/rc.conf
in order to load the
driver while booting:
kld_list+="if_urndis"
Connect the Android phone to the Laptop using a USB cable. Make sure that WiFi
and USB tethering are enabled on the phone. A new network interface
ue0
will be created once the device is connected:
# ifconfig
ue0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
ether XX:XX:XX:XX:XX:XX
hwaddr XX:XX:XX:XX:XX:XX
Enable the interface and obtain an IP address by DHCP:
# ifconfig ue0 up
# dhclient ue0
The laptop should be connected to the WiFi now.
