Can't connect to 5ghz with Intel 3165 Wifi card

[vinchiwinchi]

I upgraded my laptop from a Realtek 8723BE to a Intel 3165 AC. But I can't find my wireless 5ghz wifi. I already did a clean install on the driver and still nothing happened. I can only connect to 2.4ghz.

I have the HP Pavilion Notebook Product Number: X9K43PA#UUF
I replaced the stock Realtek wifi card for an Intel AC 3165. I asked HP support for the compatible wifi cards and this was one of them. And yet after I changed it, I still couldn't detect any 5ghz on my laptop. The driver is already from Intel. Should I use a different driver?

@vinchiwinchi 

Thank you for the update.

A few things to remember are mentioned below: 

The compatibility of your router with the wireless card, 

If the wireless card is 1x1: supports 2.4 GHz and below - slow connection and download/upload speed, 

If it's 2x2 or more: support 5 GHz and above - Fast connected and speed.
