Default New wireless controller

I just installed an Asus PCE-n13 wireless card into one of my CentOS 5.6 systems. It uses the RaLink 2680 chip set and I was able to get the driver loaded using modprobe rt2x00pci.ko. I saw no error and now see that the module is loaded along with mac80211 and other dependencies.

Now I need to know how to create the wlan0 device. I can find nothing via Google searches on how to create that device. I assumed the driver would do that upon loading, but now I expect some ioctl to the driver command may be required.

I created an ifcfg-wlan0 file, but of course ifup wlan0 always returns device not found.

Can somebody tell me where to start on getting the wlan0 device created?

What is the output of iwconfig?

What is the output of ifconfig -a

Also, in the syslog I see this when I run modprobe rt2x00pci.ko:

Now I am thinking that perhaps the driver doesn't see the new hardware. I'll try it with the adapter removed.

Hi Emmett,

Are you sure that's the right driver?

My guess is you might want the Ralink rt2860sta driver if it's a 2680
chipset. See here:

http://elrepo.org/tiki/kmod-rt2860sta

Anyway, to know for sure, please post the output from the following
command (all one line):

for BUSID in $(/sbin/lspci | awk '{ IGNORECASE=1 } /net/ { print $1 }');
do /sbin/lspci -s $BUSID -m; /sbin/lspci -s $BUSID -n; done

Also, those Ralink wireless network drivers tend to be built with
support for NetworkManager so you should generally enable the
NetworkManager service (and disable network and wpa_supplicant services)
and let NetworkManager control the device.

Another thing to check: *Most* wireless cards also need firmware, which
is not always included with the drivers, due to various copyright / IP
issues. Without the firmware, the driver won't fully initialize and not
create the device.

Yup, looks like I am trying to load the wrong driver. I assumed that if the driver loaded it found the hardware.

[root@bus ~]# for BUSID in $(/sbin/lspci | awk '{ IGNORECASE=1 } /net/ { print $1 }'); do /sbin/lspci -s $BUSID -m; /sbin/lspci -s $BUSID -n; done
01:00.0 "Network controller" "RaLink" "RT2860" "ASUSTeK Computer Inc." "Device 130f"
01:00.0 0280: 1814:0781
02:00.0 "Ethernet controller" "Intel Corporation" "82574L Gigabit Network Connection" "Super Micro Computer Inc" "Device 10d3"
02:00.0 0200: 8086:10d3
03:00.0 "Ethernet controller" "Intel Corporation" "82574L Gigabit Network Connection" "Super Micro Computer Inc" "Device 10d3"
03:00.0 0200: 8086:10d3

I'll get the correct driver.

Also, this is a specialized server, so network manager is not an option. Plus, the wireless card will be configured as an access point and I don't believe NM will allow me ot configure it that way.

Confirmed, it's kmod-rt2860sta you want.

Set up elrepo as described on the homepage here:

http://elrepo.org

then install the driver with:

yum install kmod-rt2860sta

yum will pull in the required firmware package as a dependency.

Hope that helps.
