Hi - I have done a quick search and I can not tell if my my wifi card is only setup for 2.4G or not. Do I need to replace the card to get 5G and if so what do you recommend please? Many thanks in advance.

I have checked Realtec website and the card in the PC is only 2.4G which seems crazy for a laptop 12months old. Does anyone know if I could replace the current card with a 5G one or am I better off getting a USB 5G adaptor? Thanks

Hi:

Yes, you can replace the card with this one...

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

You can buy one new from the HP parts store...11.74 pounds

or on eBay...

Below is the link to the service manual for your notebook...

The card will have the same throughput as the 8723 on the 2.4 GHz wifi band, but on the 5.0 GHz band it will have a maximum throughput of 433 MBPS with an AC router.

Here are the latest drivers for the card.  You can install them now, as they are also good for the one you have now.
