====== wifi rpi ======

===== configure key =====
Using the WNA3100M netgear adapter
<sxh bash>nano /etc/wpa_supplicant/wpa_supplicant.conf</sxh>
replace
<sxh bash>ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1</sxh>
with
<sxh bash>
network={
    ssid="your_ssid"
    scan_ssid=1
    psk="your_password"
    proto=RSN
    key_mgmt=WPA-PSK
    pairwise=CCMP
    auth_alg=OPEN
}</sxh>
reboot the rpi


knowing that :
  * ssid: your wifi name
  * scan_ssid: value of 1 means broadcast and value of 2 means hidden (suggest you enter value of 1)
  * psk: your wifi password
  * proto: your choice of RSN or WPA. RSN is WP2 and WPA is WPA1. (most config is RSN)
  * key_mgmt: your choice of WPA-PSK or WPA-EAP (pre-shared or enterprise respectively)
  * pairwise: your choice of CCMP or TKIP ( WPA2 or WPA1 respectively)
  * auth_alg: OPEN option is required for WPA and WPA2 (other option, SHARED &amp; LEAP)
