Most modern Linux distributions such as Ubuntu, Fedora, OpenSuse and many more come with the NetworkManager installed and enabled by default. This page describes the steps necessary to connect to the bfh Wifi using NetworkManager.
We've experience a whole number of troubles when connecting to the Wifi for the very first time. Unfortunately, NetworkManager is not the most stable of software. Here's a number of steps you can take in order to try to fix it.
Maybe your distribution is using another tool to manage the Networks. Also keep in mind, that NetworkManager has different frontends for Qt and GTK based interfaces. Options might be named differently in those?
The first step to take before every retry is to delete old settings you've made to the Wifi.
It has happened, that NetworkManager just stopped working correctly. Restarting the daemon might help in that case. To do that, you'll either need to be root or use sudo.
Attention! Depending on your distribution, the NetworkManager service might be named different. Common ways are
sudo /etc/init.d/NetworkManager restart
Obviously, the name of your kernel module depens on your Device's network card. If this is all too complicated for you, just reboot the computer. All of this has to be done as root.
# List loaded modules lsmod # rmmod dependencies rmmod iwldvm # rmmod the kernel module rmmod iwlwifi # reload the dependencies (the driver module will be reloaded automatically) modprobe iwldvm # restart NetworkManager /etc/init.d/NetworkManager restart
