- Make sure NetworkManager supports wifi and manages the wireless device
#nmcli d DEVICE TYPE STATE CONNECTION wlp2s0 wifi unmanaged -- enp9so ethernet unavailable -- lo loopback unmanaged
If NetworkManager doesn’t manage your wireless ethernet controller then you cannot expect it to see wifi networks and connect to them. NetworkManager would normally manage all devices automatically after a fresh boot. You might want to check presence of the wifi package. If you don’t have that package installed, you don’t have wifi support in NetworkManager.
# rpm -qa | grep NetworkManager-wifi
# rpm -ivh NetworkManager-wifi*.rpm- If you installed NetworkManager-wifi rpm package, it need restart NetworkManager service
# systemctl restart NetworkManager- Connect using nmcli, firstly you need view available wifi networks
nmcli dev wifi list SSID MODE CHAN RATE SIGNAL BARS SECURITY tplinkxxx Infra 11 54 Mbit/s 90 **** WPA1 WPA2 …
- Then choose the wifi network you want to connect, e,g: tplinkxxx
# nmcli --ask dev wifi connect tplinkxxx
Password:Finally, it will create ifcfg-tplink-xxx.cfg in /etc/sysconfig/network-scripts/ dir, and connected to wifi.
