I installed centos 7 on a laptop with an intel 6300 wireless card in it.During the install, the wireless card was available and I was able to connect to my lan.After the install, I don't see the card in the network settings.lspci shows it is there.03:00.0 Network controller [0280]: Intel Corporation Centrino Ultimate-N 6300 [8086:422b] (rev 35)How can I get centos 7 to recognize it?edit:  I see also that centos has the right firmware for this device in /lib/firmware (cross referenced with the intel website)edit 2:  this command is showing it there as a device.  How do I get it from the unmanaged state?[root@localhost network-scripts]# nmcli dDEVICE      TYPE      STATE      CONNECTION virbr0      bridge    connected  virbr0     em1         ethernet  connected  em1        virbr0-nic  tap       connected  virbr0-nic lo          loopback  unmanaged  --         wlp3s0      wifi      unmanaged  --   
Intel 6300 wireless card won't work on CentOS 7 - worked during install though!

ran yum install NetworkManager-wifi and rebooted and my wifi card showed up.was able to connect - posting this answer from that connection :)
