I put centos 7 on a little zotac box that has 2 wired adapters, and 1 wireless.
On the wireless interface, I can see both 2.4, 5 of my local wireless router. I can see my cellular hotspot. I can enter network keys and for all appearances appear to connecting. However I have not been able to ping local or remote ips.
I have set the wireless ip staticly and set to dhcp. if it sounds too weird or fubar, I can reinstall without any loss aside from time.
