Wifi not working

Bill,

Did you run the WiFi config tool on the desktop?  Are you using a Pi 2 or Pi 1.  With the WiFi dongle installed, run the following commands and let me know their output.

lsusb
sudo iwlist wlan0 scan
cat /proc/cpuinfo | grep Hardware
lsmod

When I try to config from the desktop I get the message
  " could not get status from wpa-supplicant

It all seem as if this wpa-supplicant is missing

Bill,

What does it output if you type the following.

 sudo cat /etc/wpa_supplicant/wpa_supplicant.conf  

You need to change the psk and ssid properties to match the name of your wireless device and password.

Please update the file to look like the following.  Replace MY_WIFI_NETWORK with the name of your WiFi access point, and replace MY_WIFI_PASSWORD with the password (the quotes are required).

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="MY_WIFI_NETWORK"
    psk="MY_WIFI_PASSWORD"
    proto=RSN
    key_mgmt=WPA-PSK
    pairwise=TKIP
    group=TKIP WEP104 WEP40
    auth_alg=OPEN
}

You can edit the file with nano with the following command.

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Press CTRL+X, save the file and run the following to connect the WiFi.

sudo ifdown wlan0
sudo ifup wlan0

After a while if you run the following command, you should see an IP address associated with wlan0.

ifconfig

Are the capitalized words in your response actually capitalized in the file?  For example, does it say Allow-hotplug wlan0 or does it say allow-hotplug wlan0?

When I input sudo ifup wlan0
I get

wpa_supplicant: /sbin/wpa_supplicant daemon failed to start
run-parts: /etc/network/if-if-pre-up.d/wpasupplicant exited with return code 1
Failed to connect to wpa_supplicant - wpa_ctrl-open: No such file or directory

If anyone else has this problem, it sounds very similar to a problem I had getting my wifi dongle to work with OctoPi. Here is the info I followed, I hope it helps someone else! http://www.tested.com/tech/3d-printing/ … ng-octopi/

I keep getting the same error as well. I'm using the new Raspberry Pi 2 B 1GB:
pi@atlas3d ~ $ sudo ifdown wlan0
pi@atlas3d ~ $ sudo ifup wlan0
wpa_supplicant: /sbin/wpa_supplicant daemon failed to start
run-parts: /etc/network/if-pre-up.d/wpasupplicant exited with return code 1
Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory
wpa_supplicant: /sbin/wpa_cli daemon failed to start

dmsg shows the wifi dongle

Here's my wpa_supplicant.conf file:

Not sure what else I can do. I'm running WPA2 on my router and everything else connects. With Ethernet I've updated to the latest scanning software giving me a Network screen that show's nothing in the dropdown for networks. If I use Hidden it also fails to work.

Any help appreciated.
