Windows 10: Computer Won't Show 5ghz

Hello, I've spent hours looking up forums, looking through guides, and getting help from a teach to no luck. So, my computer supports 5ghz since these are the radio types supported: 802.11n 802.11g 802.11b 802.11ac 802.11n 802.11a. I have a Realtek 8821CE Wireless LAN 802.11ac PCI-E NIC, so my drivers are up to date. My wifi supports 5ghz as well since all my other devices connect to it. However, when I go into device manager, Realtek 8821CE properties, advanced, there's only an option for Concurrent Operation Preference and it only shows 2.4ghz option. I'm curious if anybody has a way to get

:)

 

1TB WD won`t show up on my computer!

I got this problem that my Hard drive is not been seen by my laptop.I have tried many different ways solving it but it didn`t work once.I

have tried to change the letter, to format it, to turn it online but nothing works because i can`t accesse it and it show up as gray.When i open Disk Manager the computer says it is unkown and not initialized and it doesn`t show the capacity as well.When
i try to initialize it, it shows to different settings.First MBR and GPT but i have tried both of them and it shows that the REQUEST WAS FAILED DUE TO A FATAL DEVICE HARDWARE ERROR.I have also watched several YT videos but it didn`t help.I have also thought
about the cable broken but as it only 3 months new is i wouldn`t really consider it as possible.Never has it fallen or anything.It worked yesterday evening but as for today it won`t show up.

Please Help

 

5ghz wifi not showing windows 10

I just got a new modem/router and it has a 2.4ghz and 5ghz wifi connections...Only the 2.4ghz shows in the wifi list while the 5ghz isn't showing at all. My computer's network card does support the 5ghz and I know the 5ghz is working because I can connect to it from other devices...just not my desktop computer.

EDIT: I've attempted updating network driver, also resetting network in the settings menu. Both hasn't worked.
