I have HP 250 G3 J4T57EA. My WLAN is RT3290 and it's broken. I need replace with new WLAN Module. I give a screenshot bottom from HP 250 manual. Which one can I replace without problem? Thanks.

What model Intel core processor does your notebook have, and how many antenna wires are connected to the Ralink wifi card it has now?
You may be able to upgrade to a better card that those listed in the manual if your notebook has two wifi antenna wires connected to the card.
Since you already have the manual, open it up and let me know.

You're very welcome.
Yes, you are probably right about the notebook only having one antenna wire as shown in the video.
Out of the list of cards in the manual, I recommend this one...
Realtek RT8723BE 802.11bgn 1x1 Wi-Fi + BT4.0 Combo Adapter HP part # 753077-001.
That card was actually designed to work with one antenna wire.
As you can see from the pictures on eBay there is only one antenna terminal for the wire to go to.
It has decent driver support for W10.
