Wifi command line wpa iwconfig wlan0 hardware disabled rfkill

OPTIONAL unblocking radio frequencies: sudo rfkill unblock wifi

sudo rfkill list

sudo rfkill list all

0: phy0: Wireless LAN

Soft blocked: no

Hard blocked: yes

lsmod | grep dell # dell module for hotkeys, e.g. hardware switch to enable/disable wifi

modinfo dell-laptop

sudo rmmod -f dell-laptop # remove the module

sudo rfkill unblock all

sudo modprobe -v dell-laptop

sudo rfkill unblock all

Fn + F2

sudo rfkill list all # bluetooth is listed again

sudo reboot

sudo vi /etc/network/interfaces auto wlan0 iface wlan0 inet dhcp

sudo service networking stop sudo service networking start

ifconfig # should list wlan0 , if not then perhaps a driver issue

iwlist wlan0 scanning > wifi.txt # look for the highest quality (e.g. 51/70), Address: D8:C7:C8:11:22:33 (MAC Address)

iwconfig wlan0 essid "GuestNetwork" # quotes are mandatory iwconfig wlan0 mode managed iwconfig wlan0 ap d8:c7:c8:32:57:b2

sudo ifconfig wlan0 up

dhclient wlan0 # may be unnecessary

dmesg | tail # wlan0: associate with d8:c7:c8:32:57:b2 (try 1/3) , wlan0: associated

WPA using wpa_supplicant

step 1: wpa_passphrase ssidname //prompts for passkey, then outputs hex

step 2: cd /etc nano /etc/wpa_supplicant.conf

network={ ssid="networkssidname" #psk="thePassword" psk=9a285f8f38b2e8e7a4c61d8b0db40c97242dc45cf5e99ca5465580b55e111be0 }

step 3: wpa_supplicant -ieth1 -cwpa_supplicant.conf -B //starts wpa_supplicant program to connect to wifi using interface eth1 //and config file wpa_supplicant.conf in the Background (so shell continues)

step 4: dhcpcd eth1


THIS IS FOR WEP iwconfig [interface] mode managed key [WEP key]

iwconfig eth0 channel 6

essid "cali"

mode managed

key examplekey

iwconfig essid "[ESSID]"

dhclient eth0

iwlist eth1 scan iwlist [interface] key


wpa-driver ndiswrapper wpa-conf /etc/wpa_supplicant.conf


WPA-PSK/TKIP (/etc/wpa_supplicant.conf)

ctrl_interface=/var/run/wpa_supplicant

network={ ssid="example wpa-psk network" key_mgmt=WPA-PSK proto=WPA pairwise=TKIP group=TKIP psk="secret passphrase" (hex instead of ascii?) }

then run wpa_supplicant -D madwifi -i ath0 -c wpa_supplicant.conf

can try (if problems) wpa_supplicant.conf network={ ssid=" " key_mgmt=WPA-PSK psk=" " }


ifconfig eth0 up

ath0 wlan0 wifi0 eth0 //depends on the chipset (e.g. atheros) iwconfig -a

iwconfig ath0 essid 'nameofnetwork' iwconfig ath0 key 3B5D3C7D207E37DCEEEDD301E3 //wep only

iwconfig ath0 ap 03:27:A8:BC:0F:F1 //specific AP - bssid
