Difficulty Configuring and Connecting to Wifi

Post by sushemsu » 2011/10/06 22:58:11

I am having difficulty configuring my wifi on a headless centos installation
I have read over many tutorials and unfortunately don't have enough experience to determine what I am doing wrong
After reviewing the few options available, Wpa_supplicant was the direction I moved towards to using with my wpa ap, but when issuing a command to start the connection(to my knowledge) I receive a connectivity issue, and believe it's just a configuration issue.

[code]
The Command
"
wpa_supplicant -c/etc/wpa_supplicant.conf -i wlan0
"

The Error :
"
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys

Trying to associate with 00:23:69:55:83:17 (SSID='Strange' freq=2437 MHz)
Associated with 00:23:69:55:83:17
"

The Config (wpa_supplicant.conf)
"
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
ap_scan=1
network=
{
ssid="Strange"
scan_ssid=1
#key_mgmt=WPA-PSK
psk="password"
}
"

ifconfig wlan0
"
wlan0 Link encap:Ethernet HWaddr 00:26:C7:CF:8E:F4
BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:23 errors:0 dropped:0 overruns:0 frame:0

RX bytes:2599 (2.5 KiB) TX bytes:204 (204.0 b)
"

ip addr
"

The Hardware Switch is Enabled
also
Network controller: Intel Corporation Centrino Wireless-N 1000
is installed and to my knowledge the wifi hardware is supported after looking into the tutorial on the centos wiki for the drivers on the Centrino Wireless-N 1000 adapter

With the upstream move toward increased use of GUI interfaces and a default of NetworkManager rather than the network service it seems configuring without a GUI has become more difficult and is certainly not well documented. NetworkManager wants to run it's own copy of wpa_supplicant and that may interfere with your efforts.

Please provide a link to the instructions you were following, and [url=http://www.centos.org/modules/newbb/viewtopic.php?topic_id=28723&forum=54]provide more information about your system[/url] by running "./getinfo.sh" and showing us the output file.
