raspberyypi-2 , wlan0 get no IP number

[backslash]

trying to get wifi dongle to work

/etc/network/interfaces

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet dhcp
#wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
wpa_ssid MIJNSSID
wpa_psk MIJNWACHTWOORD
iface default inet dhcp

ps

SSID = MIJNSSID

and

SSID = MIJNSSID 2,4 GHz

(first is 5 GHz)

where do i go wrong?

All you need is:

Code: Select all

auto lo

auto eth0
iface eth0 inet dhcp

auto wlan0
allow-hotplug wlan0

iface wlan0 inet dhcp
   wpa-ssid SSID
   wpa-psk HASHEDPASSWORD


HASHEDPASSWORD comes from:

Code: Select all

wpa_passphrase SSID PASSWORD


it will spit out the hashed edition that can be included in the /etc/network/interfaces config above.
