Wireless issue with WCA6174

[pegruder]

Hey folks, running CentOS 7.4 on a new Lenovo Yoga 920 with the QCA6174 wifi adapter and am having issues. When I toggle the wifi to on nothing seems to happen. I've tried recommendations from various posts including trying the elrepo with no luck. Any ideas?

lspci -nn | grep -i Net
6b:00.0 Network controller [0280]: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter [168c:003e] (rev 32)

modprobe ath10k_pci and see if your interface then appears in the output of `ifconfig -a` or `ip link show`

Well I'm not sure how you've managed to get an enp0s20f0u1 (looks like wired) and an wlp107s0 interface but the wl one is a wireless one. Now you need to configure it using nmcli/nmtui or manually using an ifcfg file.

I do have a USB wired adapter connected at the moment which should be why thats showing up. I'll try and configure it but it tells me unavailable:
