HP Laptop running Realtek RTL8723DE 802.11b/g/n PCIe Adapter unable to select 802.11 n

HP Laptop running Realtek RTL8723DE 802.11b/g/n PCIe Adapter

When configuring the device, in "Wireless Mode", I only have 3 options:

1: 802.11 b

2: 802.11 g

3: 802.11 b/g

I am unable to set 802.11 n as it's not shown in the drop down menu.

Just trying to get a faster network connection - currently on 2gbs fiber, but my average speed test is 52 down and 43 up.

Hi:

The default and best setting is b/g.

The maximum throughput of that model Wi-Fi adapter is only 72 MBPS.

That would be with an excellent Wi-Fi signal.

Not bad for that lousy model Wi-Fi adapter.

You can verify the speed the adapter is connecting at by going to the Windows control panel>network & internet>network & sharing center>then on the right side of that window, click on the Wi-Fi connection you see listed there.

If you are good at taking things apart and better at putting them back together again, you can upgrade that model Wi-Fi adapter to a dual band AC card.

Realtek RTL8821CE 802.11 ac 1x1 Wi-Fi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005.

The card has a maximum throughput of 433 MBPS on the 5.0 GHz Wi-Fi band with an AC router and an excellent signal.

You can find this model on eBay, or Ali Express. 

I see some Intel 3165 cards listed on the eBay listings, so don't buy those.

On the Ali Express listings, make sure the card has the HP Part # of 915620-001.

Below is the link to the service manual, where you can find the Wi-Fi card removal and replacement procedure.
