Realtek RTL8821CE 802.11ac Won't Connect to Home Network

[ItsJustGreg]

I recently purchased this desktop and am trying to get it to connect to my home wifi network, but no matter what I do, it keeps saying "Can't connect to this network."

I've tried deleting the drivers and forcing Windows to re-install them when I reboot. I've tried manually setting the adapter to different modes (x.11b, x.11g, x.11b/g/n, auto). The only one of those options that even lets me select my home network is the auto setting. I've also tried disabling TCP/IPv6 and manually selecting my bandwidth (2.4GHz or 5GHz). I also tried connecting to the network manually, but with the same result. "Can't connect to this network."

All of my other devices are connected with no problem. My phone, my laptop, my husband's phone and laptop.

Any suggestions on how I can go about fixing this issue?

Hi

Copy, Paste and Save in Notepad, as LBB.bat (not a .TXT) and double click to run.
Preferably run as an Administrator.
OR
Copy and use the individual command lines as needed.

Post anything non-personal, but relevant please.

 OFF
getmac
netsh lan show interfaces
netsh wlan show interfaces
netsh wlan show drivers

systeminfo
PowerShell -Command "Get-NetAdapter"
PowerShell -Command "Get-NetAdapter -Name * | Format-Table -View Driver"
PowerShell -Command "GIP -Detailed"
PowerShell -Command "Test-NetConnection"

Turns out the antenna wire came disconnected during shipping. Snapped it back on and we're good to go! Actually posting this from my new machine!
