Hi, I have a similar question. I have a Realtek RTL8723DE 802.11b/g/n PCIe Adapter on an HP 15-db1903ng laptop. I would like to update my laptop to the 5g band. My router already supports it and I can access the dual band with other devices. I would highly appreciate useful advice. Many thanks.

Hi:

 

Since your notebook only has one antenna cable, there is only one dual band AC wifi card you can upgrade to.

 

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


The only place I have been able to find this model is on eBay.

The card has the same throughput as the RTL8723DE on the 2.4 GHz wifi band, but on the 5.0 GHz wifi band with an AC router, it has a maximum throughput of 433 MBPS.
