Wireless Interface Detected, but Not Detecting Networks
« on: June 13, 2010, 03:55:16 AM »
I am using the Gnome version of PCLinuxOS (kernel: 2.6.32.11-pclos2)

My wireless interface is apparently properly detected (RT2561 / RT61) and the module is loading, but wireless networks are not being scanned or identified.  The wireless network I'm trying to connect to is type WPA2-Mixed.

I believe I had this problem with the KDE version of 2009.2, and it was a simple fix,  but I can't remember what that was.

Here is some diagnostic output:

[root@hostname ~]# lspci
02:03.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
02:09.0 Network controller: RaLink RT2561/RT61 rev B 802.11g

[root@hostname ~]# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

wlan0     IEEE 802.11bg  Mode:Managed  Access Point: Not-Associated   
          Tx-Power=0 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
         
[root@hostname ~]# wpa_cli list_networks
Failed to connect to wpa_supplicant - wpa_ctrl_open: Success


Here are some of the files:

There was no /etc/sysconfig/network-script/ifcfg-wlan0 , so I created one and attempted to restart networking:


[root@hostname ~]# /etc/init.d/network restart

Problem solved.

In my defense, the wireless button is right next to the power button and I swear the wireless LED doesn't always work.

ROFL!  No need to defend yourself.  I hate switches.   ;D :D
