Ts47xx WIFI
This board optionally supports 802.11 through the WIFI-N-USB-2 module using the ath9k_htc driver.
Scan for a network
ifconfig wlan0 up
# Scan for available networks
iwlist wlan0 scan
In this case I'm connecting to "default" which is an open network:
Cell 03 - Address: c0:ff:ee:c0:ff:ee Mode:Managed ESSID:"default" Channel:2 Encryption key:off Bit Rates:9 Mb/s
To connect to this open network:
iwconfig wlan0 essid "default"
You can use the iwconfig command to determine if you have authenticated to an access point. Before connecting it will show something similar to this:
# iwconfig wlan0 wlan0 IEEE 802.11bgn ESSID:"default" Mode:Managed Frequency:2.417 GHz Access Point: c0:ff:ee:c0:ff:ee Bit Rate=1 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=70/70 Signal level=-34 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0
If you are connecting using WEP, you will need to define a network key:
iwconfig wlan0 essid "default" key "yourpassword"
If you are connecting to WPA you will need to use wpa_passphrase and wpa_supplicant:
wpa_passphrase the_essid the_password > /etc/wpa_supplicant.conf
Now that you have the configuration file, you will need to start the wpa_supplicant daemon:
wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -B
Now you are connected to the network, but this would be close to the equivalent of connecting a network cable. To connect to the internet or talk to your internal network you will need to configure the interface. See the #Configuring the Network for more information, but commonly you can just run:
dhclient wlan0
Note: | Some older images did not include the "crda" and "iw" packages required to make a wireless connection. If you cannot get an ip address you may want to connect over ethernet and install these packages with "apt-get install crda iw -y". |
