I recently installed CentOS 7 as the sole OS on an Acer Aspire T. There is no GUI, as it is a server with a terminal-only interface.
What do I need to do to get CentOS 7 to be able to see and list the available wifi connections?
When I use the Network Manager Command Line Tool nmcli, I get the following, which indicates that nmcli has wifi enabled, but that it cannot see any wifi connections:
[root@localhost ~]# nmcli general status STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN disconnected none enabled enabled enabled enabled [root@localhost ~]# nmcli connection show NAME UUID TYPE DEVICE [root@localhost ~]# nmcli device status DEVICE TYPE STATE CONNECTION eno1 ethernet unmanaged -- lo loopback unmanaged -- wlp3s0 wifi unmanaged -- I then checked the firewall config, which shows that ssh is the only open service, as follows:
[root@localhost network-scripts]# firewall-cmd --list-all public (default, active) interfaces: eno1 sources: services: dhcpv6-client ssh ports: masquerade: no forward-ports: icmp-blocks: rich rules: What do I need to change in order to get CentOS to be able to see the wifi connections? There are available connections. Does the firewall need to change? Or something else?
EDIT:
I am not able to do the things that @TimS. suggested because the following tools are not pre-installed on the computer, and it is not connected directly to the internet:
[root@localhost ~]# ifconfig -a -bash: ifconfig: command not found [root@localhost ~]# lspci -v -bash: lspci: command not found [root@localhost ~]# iw dev -bash: iw: command not found [root@localhost ~]# iwconfig -bash: iwconfig: command not found I am able to open nmtui, but am not sure what parameters to enter to create a new connection. [root@localhost ~]# iw dev -bash: iw: command not found [root@localhost ~]# iwconfig -bash: iwconfig: command not found
