Are you able to find that the wireless card supports 5GHz?

I would suggest you to follow the below steps:

1. Press Windows key + X, open Device Manager, right-click on your wireless adapter, and choose "Properties"
2. Under the "Advanced" tab, scroll down to "Wireless Mode" and make sure that you select is 802.11a/ac

It is not compatible..I have the same card. 

The only way around is to get an external USB WiFi card that supports 5G 

I was pretty bummed because it is a brand new HP laptop and I didn't even think to check the WiFi specs.

Dear Neha,

My laptop uses REALTEK RTL8723AE Wireless LAN 802.11 PCI-E NIC, same as Andy D who posted this forum, and i was also trying to connect to a 5gHz wifi. 

But it seems like my laptop is only able to detect 2.4gHz wifi. I have searched online and found that I can check what radio type is my computer supported by going to the command prompt and type in, "netsh wlan show driver" command. I did and it shows :

Radio type supported : 802.11n 802.11g 802.11b

I am kind of confuse as i searched that laptop with 802.11a, 802.11ac and 802.11n is able to connect to 5gHz wifi, but mine showed this 3.

And when I went into the wireless adapter and right click for porpertise of "REALTEK RTL8723AE Wireless LAN 802.11 PCI-E NIC", under advance tab I can only see 802.11d. Beside the value drop down disable and enable. It is currently showing disable.

You state that "scroll down to the 'Wireless Mode' and make sure you select 802.11a/802.11ac", but the value of Wireless Mode only showed: Auto, IEEE 802.11b, and IEEE802.11b / g.

So I'm wondering if REALTEK RTL8723AE Wireless LAN 802.11 PCI-E NIC wireless adapter if supported to 5gHz wifi or not? If yes, how do I connect to it? If no, is there anything i can do to make it possible?

I am using realtek rtl8192ce adapter. in the advanced settings. i can only enable 802.11d because it doesnt have other options such as 802.11a or n or etc.

is it because the device is too old to support those new protocols?

this may be a bit late but i had found a dated wifi receiver in a laptop with a 802.11d (1/0). i managed to dig up what is exactly going on but. 802.11d is a spectrum compliance addition that can rely on the AP to supply the protocol which is being leased without bias against the receiver. once i turned it on....my 5ghz were veiled behind a "hidden network" SSID. so, knowing its SSID and WPA....i  was leased a channel 0 along with no 2.4/5ghz frequency. it quickly found US standard channeling and default 2.4ghz and assigned it accordingly. it will hook in at any compliant channel and GHz...but it will only follow the AP and at the very least fail switch to regional defaults
