HowTo: WPA with wpa_supplicant

**kevdog** · November 16th, 2009

I love doing it manually as well, but is there some reason you have to do this manually? Network Manager or WICD isn't sufficient?

Ok, I need to pick someone's brain.

I have an old Dell Inspiron 5100 that I just picked up a Broadcom internal wireless card for (BCM4309). I installed the B43legacy driver for it, and managed to get it connected using NetworkManager. Only one problem. It connects at 80-90% signal strength, but the speed is slow to none (i.e. it only actually resolves websites on rare occasion).

So I disabled NetworkManager, and tried the steps in this tutorial. Same thing. It *sometimes* connects, and when it does, the speed is dead slow.

Any ideas as to what might be causing this?

Hmm, Network Manager fails to connect. It spends ages trying and then eventually 'fails' showing the form to enter the passcode. I had tried wicd but as 9.10 reinstalled Network Manager hadn't tried again. Thought I'd get it working manually first.

When I open interfaces to place those two lines in, it has nothing with in it. I'm a noob so I don't know if that's a problem or not.

It's been roughly 4.5 years since this how to was created and for those that wonder if it still works the answer is YES.
I disabled network manager under System > Preferences > Startup Applications
and am now connected without it using 9.10.

Actually I'm using Ubuntu Ultimate Edition 2.5, which is based on 9.10, so if you don't have Startup Applications you can install it with

Code:

sudo apt-get install gnome-session-properties

For those using AES encryption instead of TKIP just change them around in the instructions when doing it.

EDIT: I also removed these 2 lines, otherwise I would get an error.

pairwise=CCMP AES
group=CCMP AES

Thanks to the OP for the how to, to Chili555 for pointing me to it, and to others that have added to it over the years.

This is by far one of the most helpful howto's in this entire forum. I keep coming back every few months when I have to re-install my system cause I play around with it too much..

Works every time!

I only read the first three pages of posts but it still helped me a lot. I just tried FreeBSD and had to configure wireless 'manually' with wpa_supplicant because of the Atheros based PCMCIA card. It was basically the same thing. Here's what my .conf file looks like if it will help anyone:

Code:

ctrl_interface=/var/run/wpa_supplicant
network={
  ssid="my_access_point_name"
  proto=WPA
  key_mgmt=NONE
  wep_key0=<10 digits in here - no quotes>
  wep_tx_keyidx=0
}

So there is a _lot_ of possibilities in that file.

Thanks for the help.

Oh yeh - this was in Xubuntu FWIW

Hi,

I'm trying to connect to a AP by command line but I can't yet. Using the network manager it's possible but I need the command lines to use in my code programming.

Here it's what I tryed:

Code:

sudo iwconfig wlan0 mode managed channel 6 key restricted s:'12345' essid 'cassiano-PC_AP'

and the tail: sudo tail -f /var/log/syslog

Code:

05:55 cassiano-linux kernel: [13476.935795] wlan0: direct probe to AP 00:15:af:84:29:d3 (try 1)
Aug 13 14:05:55 cassiano-linux kernel: [13476.935943] wlan0: deauthenticating from 00:15:af:84:29:d3 by local choice (reason=3)

Aug 13 14:05:55 cassiano-linux wpa_supplicant[828]: CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys

I think that the error is:

Code:

Aug 13 14:05:55 cassiano-linux wpa_supplicant[828]: No network configuration found for the current AP

And when I connect with the network manager appears this on the tail:

Code:

NetworkManager: <info>  Activation (wlan0/wireless): connection 'Auto cassiano-PC_AP' has security, and secrets exist.  No new secrets needed.
Aug 13 14:31:31 cassiano-linux NetworkManager: <info>  Config: added 'ssid' value 'cassiano-PC_AP'

Aug 13 14:31:31 cassiano-linux NetworkManager: <info>  Config: added 'wep_tx_keyidx' value '0'

and this:

Code:

Aug 13 14:31:32 cassiano-linux wpa_supplicant[828]: Associated with 00:15:af:84:29:d3

My /etc/wpa_supplicant.conf

Code:

ctrl_interface=/var/run/wpa_supplicant

network={

        scan_ssid=1

        auth_alg=OPEN
        wep_key0="12345"
        wep_tx_keyidx=1
}

And when I run this:

sudo wpa_supplicant -dd -iwlan0 -c/etc/wpa_supplicant.conf

Code:

The easiest way to configure wpa_supplicant is to connect to a wireless network using NetworkManager and then copy the config settings out of the daemon logs. This post here shows you how.

**PatchesTheCaveman** · January 4th, 2011

Hi t_anjan. Happy New Year!

For iwconfig to return useful output, you must run it as superuser:

Code:

sudo iwconfig

Unfortunately, I have no experience with ndiswrapper so I can't help you with that.

However, there is a native Linux driver for your wireless adapter I'd be glad to help you get working if you're interested.
