| − | This article explains how to connect to a wireless network with Linux. It has been tested with SUSE Linux 12.2. For the commands below you need to be logged in as root user.
| + | There shouldn't be any siniifncagt differences between 2005.0 and 2005.1. I've yet to get the standard gentoo wireless configuration working, but it's not been a huge issue as the RaConfig2500 seems to work ok. All in all things are still working fairly well with the exception of my DVD burner, which appears to have failed. I'm debating sending it back for warranty replacement or just buying a new one and putting it in myself. |

| − | Find out what wlan devices you have
| |
| − | # hwinfo --wlan --short
| |
| − | network:
| |
| − | ''wlan0'' Ralink 802.11 bg WLAN
| |
| − | In this example, you have one wireless network device. It is named ''wlan0''.
| |
| − | | |
| − | = Activate the card =
| |
| − | In this example we will use SUSE Linux 12.2 and a Conceptronic USB WLAN adapter with a RALink chipset. To activate the card, set it up with
| |
| − | yast2 lan
| |
| − | Yast will offer to install the packages iw and kernel-firmware as well. This is important because the firmware must fit to the drivers' version. So accept installing iw and both iw and kernel-firmware will be installed. Then yast will create a script /etc/sysconfig/ifcfg-wlan0 containing your device's parameters. If you select it, yast will also do everything around wpa-supplicant so you can use WPA secured WLAN.

| |
| − | ifup wlan0
| |
| − | | |
| − | And your device will be activated.
