System is Tumbleweed with KDE Plasma desktop. I have been following the "Network Manager and my 'Use Case' thread with interest and have managed to setup a working ethernet network connection using systemd-networkd, thanks to the examples posted there. I also have a wireless card in this computer, and was using Network Manager to manage both wired and wireless connections. Now that I have disabled Network Manager, I would like to find a similar systemd-networkd solution for my wireless card. I believe I have to use wpa_supplicant to communicate passwords etc with the router, followed by the systemd-networkd configuration. I have created /etc/wpa_supplicant.conf --- ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=wheel # home network; allow all valid ciphers network={ ssid="Hillingdon Wi-Fi" <== Name as seen by mobile phone, for example scan_ssid=1 key_mgmt=WPA-PSK psk="my-wifi-password" <=== not the real password } --- But when I do # wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -d wpa_supplicant v2.10 Successfully initialized wpa_supplicant Initializing interface 'wlan0' conf '/etc/wpa_supplicant.conf' driver 'default' ctrl_interface 'N/A' bridge 'N/A' Configuration file '/etc/wpa_supplicant.conf' -> '/etc/wpa_supplicant.conf' Reading configuration file '/etc/wpa_supplicant.conf' ctrl_interface='/var/run/wpa_supplicant' ctrl_interface_group='wheel' Priority group 0 id=0 ssid='Hillingdon Wi-Fi' Could not read interface wlan0 flags: No such device nl80211: Driver does not support authentication/association or connect commands nl80211: deinit ifname=wlan0 disabled_11b_rates=0 nl80211: Remove monitor interface: refcount=0 netlink: Operstate: ifindex=0 linkmode=0 (kernel-control), operstate=6 (IF_OPER_UP) Could not read interface wlan0 flags: No such device wlan0: Failed to initialize driver interface Failed to add interface wlan0 wlan0: Cancelling scan request wlan0: Cancelling authentication timeout Off-channel: Clear pending Action frame TX (pending_action_tx=(nil) QM: Clear all active DSCP policies wlan0: CTRL-EVENT-DSCP-POLICY clear_all There seem to be two problems: 1. No such device (fatal!) 2. Driver does not support authentication - but NM succeeded in setting up a connection. Can anyone suggest what I'm missing here, please? TIA -- Bob Williams No HTML please.
