I want to add a bt card to my Dell laptop. I have not been able to find one. I keep finding wi-fi cards that bundle bt and wi-fi but they only have 2 terminal connections and my current wi-fi card has 3. Anyone seen such an animal?
Below is my current wi-fi card.

The three connection cards went out of production long ago. Switching to a modern card will improve both wifi and bt.
Thanks for the info. If I go with a 2-terminal card which of the 3 wires do I use? Or do I just rotate through the possible combos and see what happens

Two of them should go up behind the screen and those would be my choice. You might be able to just remove the hinge caps to find out which ones or look for the stray that runs down the side or back cover.

If you're ambitious you could order better antennas and stick them behind the screen or slide them into the bezel on the sides.

Not worried about the antenna; I just want the bluetooth added for my wireless earbuds. Many of the 2-terminal wi-fi cards come with bluetooth, or so they advertise. Not sure how that works. I'll look at the wire routes. Not that many combos to try anyway. Thanks.

They've been that way for quite awhile now. Back in the day though there were little cards that plugged in independently though like match sticks for BT. I mean for $20 it's not a huge cost for both. Since your primary is just for BT then going with a cheaper $5 card should suffice unless you want better BT distance or the earbuds use a higher revision of BT. Newer cards are always backwards compatible with lower versions but, old cards don't always work with newer devices.

IIRC the Intel AX210 comes in a mPCIE format as an option. I don't think the current / newer BE options would work besides some of the stupid OS requirements to deal with.

I looked at the bios and can't tell. How do I tell? Can I tell?

It would be in the BIOS code, not an option configurable to the user. But after searching the interwebs, it appears DELL is among the better of the manufacturers for NOT white listing WLAN/BT adapters in their laptops.
