Re: [CentOS] Need help configuring wireless NIC
Hi Marko if your WLAN interface does not show up in ifconfig or in ls -l /sys/class/net/ then - your system recognizes that it has to load the modules you mention when you plug in your WLAN interface - but the modules are incapable to install the interface correctly if you say you cannot bring to work ndiswrapper because its compilation fails, then you are in bad luck. I once had a similar problem with a D-Link card (featuring the adx TI-chip). What I did: I waited until a new version of ndiswrapper was available, compiled this one, and off I went. suomi On 03/27/2012 08:46 AM, Marko Vojinovic wrote: On Tuesday, 27.

[CentOS] Need help configuring wireless NIC
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 help...). 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 lib802114194 1 libertas How do I find out the name of the device, and how do I create the ifcfg script properly?
