Realtek RTL8821CE 802.11ac PCIe Adapter issue

[Gamer10]

Hello,
I am having trouble with my PCIe adapter(Realtek RTL8821CE 802.11ac PCIe Adapter) with the n/ac technology. 2.4 GHz works perfectly fine and the a/b/g technology works also fine. The problem is that n/ac is not showing so I can't change it to n or ac technology and if I want to have 5GHz I have to switch to a technology to have 5GHz.

I think I have try all the possible methods to fix this. At first about 2 weeks ago i went to the official hp's driver's page so i downloaded /Realtek RTL8xxx Wireless LAN Drivers/ 

So after installing it my driver is: 2024.0.10.223

After that nothing changed so I went ahead reading all the forums and tech pages suggesting things like changing the adapter setting 

1-Power management to unchecked the (allow the computer to turn off this device to save power)

2- Mixed mode protection change to (RTS/CTS enabled)

3- Under wireless mode... On advance adapter properties vales it only shows 802.11a/b/g availability in here i suppose it is suppose to show  802.11n and 802.11ac as well but it isn't showing. This is the only suppositions i have about the driver.

Can you help me out with this? it looks like the adaptor might be the problem. After i google it i have found many people complaining about this issues with the same adapter.  would it be any way to fix this?

Also sorry for the bad english it's not my first language

Hi:

There is no such setting as AC on that model wifi adapter.

Please see this discussion to discover that your notebook is connecting at a faster throughput than wireless N on the 5 GHz wifi band.

Things you can try that the person in the discussion did...

1.  Make sure your router is broadcasting your WiFi's SSD on the 5.0 GHz wifi band.

2.  Set up 80 MHz bandwith on the router

If nothing resolves the problem and you still cannot connect to the 5.0 GHz wifi band at all, then the card must be defective.
