Question Can you use a USB WiFi dongle to get better WiFi to a laptop even if that laptop already has a built-in WiFi card?

Hi everyone.

My laptop has a built-in WiFi card (Realtek RTL8822BE 802.11ac PCIe Adapter).

Can I use a USB WiFi dongle to improve my laptop’s WiFi reception or is it pointless since my laptop already has a WiFi card built in?

I believe my laptop has an up-to-date WiFi card built into it, but I’ve seen some USB WiFi dongles and many of them come with a pretty substantial antenna on them like the one:

If I used a USB WiFi dongle like the one in the link above, would it even work since my laptop already has a built-in WiFi card? For instance, would any WiFi drivers required to run the USB WiFi dongle interfere with the WiFi drivers that run my laptop’s built-in WiFi card?

I know these are a lot of questions to answer, but I thought it made sense to put them all in one place and I didn’t find answers to these questions anywhere else.

The essence of my question though is this: Would it be beneficial for me to get a USB WiFi dongle like the one shown in the link above in order to improve my laptop’s WiFi reception even though my laptop already has a built-in WiFi card?

Thank you.
