Hi everyone! :-)

Yesterday I managed to find a driver for my USB wireless dongle, and it is now 
correctly recognized by the kernel. However, I don't know how to configure it. 

The system-config-network opens up in text mode and is not very forthcoming (it 
lists ethernet, ISDN and modem as possibilities for configuring a new device). 
I don't know how to create an /etc/sysconfig/network-scripts/ifcfg-whatever 
manually for my wireless card. NetworkManager doesn't see the device since the 
ifcfg* script doesn't exist. What am I supposed to do? (Google also didn't 

The device is listed by lsusb as:

# lsusb | grep 802
Bus 001 Device 005: ID 1286:1fab Marvell Semiconductor, Inc. 88W8338 
[Libertas] 802.11g

The libertas kernel module is loaded:

# lsmod | grep liber
libertas              105931  0 
cfg80211              164625  1 libertas
lib80211                4194  1 libertas

How do I find out the name of the device, and how do I create the ifcfg script 

Best, :-)
