5Ghz (a/ac) Wlan cards/modules compatible with HP Notebook - 15-da0070tx (4ST50PA)

[SubinPT]

Hello All,

I am stuck with an HP Notebook - 15-da0070tx, which has only 802.11b/g/n WiFi supported. Gives me about 60Mbps if I sit right under the WiFi router. I do have a broadband connection with 200Mbps. I was wondering if there is a compatible WLAN + BT or Wlan module which supports 5GHz - a/ac band, to replace the built in one (mini pci I guess). Trying to keep the USB ports free and the existing Realtek module is a big pain while using Linux if I have to reinstall.

Thanks and Regards,

Subin

Hi, Subin:

Since your notebook has a single band Realtek wifi adapter, it only has one antenna wire, so the only dual band AC wifi card you can do a direct swap to and have everything work as expected, would be this one.

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,

The card will have the same 72 MBPS throughput as the Realtek 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.

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

The service manual, in the WLAN replacement section lists below parts,

WLAN module Description Spare part number

Not really a fan of Realtek anymore. What about the intel one ?

If you don't want/need the Bluetooth to work, both of these cards should work...wifi only.

The below two cards require two antenna wires be connected to the card in order for the Bluetooth to work, and your notebook only has one.

Intel Dual band wireless-AC 3168 802.11AC 1×1 WiFi + Bluetooth 4.2 Combo Adapter (non-vPro)   863934-855

Realtek RTL8822BE 802.11 ac 2×2 WiFi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported)       924813-855

You already have the last one on the list installed.
