After using Networkmanager and Wicd for a few years each I craved for a less complicated networking setup on my laptop. I did some reasearch and found that nothing outthere fits my need so I decided just to use the minimal basic setup.


I created a simple network file to use systemd to do the DHCP:




The Name tells systemd on which interfaces the config should be applied. wlp* would also be valid The DHCP Parameter should be selfexplaining. ipv4 would also be valid. The RouteMetric tells systemd that any route announced by the DHCP Server should get this specific metric. I use a lower metric for any routes on my wired interfaces to force traffic to go through the cable if possible.


Ofcourse wpa_supplicant is nessesay on Linux to use any kind of Wireless network. I use wpa_gui for the lazy hours to create the config for me. Writing/Editing the config manually is still needed sometimes

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=network


This is as simple as possible. ctrl_interface defines the socket on which wpa_ui or something simalar can connect to wpa_supplicant update_config allows wpa_supplicant to overwrite the configfile if nessesary. ap_scan tells wpa_supplicant to decide which network to connect to. It would be also possible to let the driver to that (ap_scan=0)

After a while I found out that wpa_gui creates the network config snippit with the disabled=1 parameter by default. This prevents wpa_supplicant from connecting to the network automatically if while by scanning. For most networks I disable this parameter manually.

wpa_supplicant.conf (5)
