I can not connect to wifi when centos starts

[mikefy]

Hi guys, I've installed centos7 on my 7 years old laptop. But it can't connect to Wifi automatically when it starts. I dont want to install GUI, the laptop is too old to run it, so I want to use the command line to setup this. I also read this https://wiki.centos.org/zh/HowTos/Laptops/WpaSupplicant, but it can not connect either. Would some guys can tell me how to setup step by step.... I've worked on it for 2 days. Thank you guys so much!

Setup your wifi via the NetworkManager.service

[sidusnare]

After installing NetworkManager, your connections are in /etc/NetworkManager/system-connections/
You can add connections with

Code: Select all

nmcli con add

You can use this as a template to compare your connections to

Code: Select all

[connection]
id=MYNETWORKNAME
uuid=########-####-####-#####-#############
type=802-11-wireless
permissions=group:users:;

[802-11-wireless]
ssid=MYSSID
mode=infrastructure
security=802-11-wireless-security

[802-11-wireless-security]
