My notebook is described equipped with Realtek 802.11a/b/g/n/ac (1x1) Wi-Fi in HP official website. However, i checked my notebook, it is physically installed with Realtek RTL8723DE 802.11b/g/n PCIe Adapter which is not supportable for dual wifi with frequencyh 2.4GHz and 5GHz. Is this a typo error on HP website or it was a manufacturing defect on my notebook? Pls advise.
The card will have the same 72 MBPS throughput as the RTL8723DEon 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.
Below is the link to the service manual, where you can find the wifi card removal and replacement procedure.
