[SOLVED] Connecting to a network via console

Dornith · 09-14-2013, 09:54 AM

I just installed CentOS and I want to learn the tools for connecting to the internet without Gnome. Right now I'm trying to connect to my home network but I can't get it to work. I turned off Network Manager and am currently working as root. I'm pretty sure we use WPA2 with dhcp and ipv4 and I checked that the driver is up to date. Here's what I've tried:

Code:

iwconfig wlan0 essid <NetworkId> key s:<Password>
    SET failed on device wlan0 ; Invalid argument

wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -Dwext
Trying to associate with 00:13:10:ec:77:ce (SSID='<NetworkId>' freq=2452 MHz)
Associated with 00:00:00:00:00:00
CTRL-EVENT-DISCONNECTED bssid=00:13:10:ec:77:ce reason=0
Associated with 00:13:10:ec:77:ce
WPA: INVALID EAPOL-key MIC when using TPTK - ignoring TPTK
WPA: Could not verify EAPOL-Key MIC - dropping packet

This is my /etc/wpa_supplicant.conf:

Code:

network={
	ssid="<NetworkId>"
	psk="<Password>"
	key_mgmt=WPA-PSK
}

I figured out the problem, a bunch of little things.

Firstly I had to convert my password with wpa_passphrase like so:

Code:

wpa_passphrase <NetworkId> > /etc/wpa_supplicant.conf
<Password>

Secondly, I had to take wlan0 down (I thought I already did but that was before I turned of Network manager so it might have turned it back on):

Code:

ifconfig wlan0 down

So in final what I had to do was this:

Code:

su
<RootPassword>
service NetworkManager stop
# chkconfig NetworkManager off #Uncomment this to make it permenant
ifconfig wlan0 down
wpa_passphrase <NetworkName> > /etc/wpa_supplicant.conf
<NetworkPassword>
wpa_supplicant -Dwext -iwlan0 -e/etc/wpa_supplicant.conf
dhclient -r
dhclient wlan0 #This one might take a moment
ifconfig wlan0 up
exit
