Upgrading realtek RTL8723DE 802.11b/g/n PCIe Adapter to a compatible dual band wifi adapter

[Alexio935]

Hi, my laptop is HP 15-da1003nl  with i5 8th Gen chipset, 8GB RAM and 256GB SSD. 

The Wi-Fi adapter of this laptop Realtek RTL8723DE 802.11b/g/n which supports only 2.4Ghz Wi-Fi band. I want to upgrade the adapter to a dual band one which supports 5Ghz band too. Any help would be highly appreciated.

Thank you all in advance!

Hi:

Yes, you can upgrade the card to this model...

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

You can find this model on eBay, or Ali Express.  I see an Intel cards listed at the top of the eBay listings, so don't buy those.

RTL8821CE - Buy RTL8821CE with free shipping on AliExpress

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

You can also buy it directly from HP...

HP Parts Store: parti per computer HP, parti per stampanti HP e parti Compaq

The card will have the same 72 MBPS throughput as the original wifi card on the 2.4 GHz wifi band, but on the 5.0 GHz wifi band, it will have a max throughput of 433 MBPS when you have an AC router with an excellent wifi signal strength.
