Unable to activate wifi on Linux

[pfeerick]

Glad it's all working now!

I never bother with iwconfig unless there is something wrong that needs diagnosing... I just make sure the /etc/network/interfaces has something like this in it...

Code:

auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

and in /etc/wpa_supplicant/wpa_supplicant.conf I have (at a minimum)

Code:

network={
ssid="YOUR_NETWORK_NAME"
psk="YOUR_NETWORK_PASSWORD"
}

and wireless comes up on reboot or with 'sudo ifup wlan0' ... but there's more than one way to skin a cat. Thanks for posting the steps for other people. More ways you know how to do it the better... then you can pick which way you prefer!

Well in fact it works ...
Simply iwconfig tool is not installed by default in Ubuntu longsleep image

Here is the way to activate wifi:


sudo apt-get install wireless-tools
iwconfig
sudo ifup wlan0
sudo iwconfig wlan0 essid "Use this one Mom"
# wpa_passphrase essid pwd > /etc/wpa_supplicant.conf
sudo wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf
sudo dhclient wlan0

Hope it may help others
