I am new in Linux. Today I installed the SUSE Linux 11 then with the wifi I cant connect to the internet. I have the following system information:

SUSE Linux Release 11,
Kernel Linux
Gnome 2.28.2

If I navigate to YaST-Hardware Information there is Wireless LAN tab and this has a 'Realtek WLAN controller' value.

In GNOME Terminal I execute the following commands and get the below values:

01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 8176 (rev 01)

/sbin/lspci -n
02:00.0 0280: 10ec:8176 (rev 01)

lo no wireless extensions.

eth0 no wireless extensions.

sudo /usr/sbin/iwlist scan
lo Interface doesn't support scanning.

wlan0 Scan completed :

eth0 Interface doesn't support scanning.

In Yast/Network devices/Network settings on the Global Options tab
Network setup method is set to User controlled with network manager value. On the
Overview tab I get the following information: Realtec WLAN controller(Not connected).

On the main navigation bar,i n the right down side the network connection icon appear but the status is : No network connection. If I right click on it the Enable networking and enable wireless checkbox is set on. If I click on edit connection on wireless tab I create a new connection. After that I cant connect to any wireless network.

What I am doing wrong or what I have to install in order to connect to the Internet? Thank you for your help.
