I have a few basic questions that can't be too difficult. What part number should I use when shopping for a new WIFI card? The one in the subject line doesn't really seem to get a positive answer (that I understand). The antenna has dislodged from the card and I don't know how to reattach it. Does a new card come with an antenna? If not, do you have suggestions to reattach the antenna I have? TIA

Get a magnifying glass or some cell phones have that feature, and check the wifi card and see if the antenna connector broke off the card and has become lodged inside of the antenna connector.
If it has, you may be able to dig the broken connector out of the wire using a pin and some needle nose pliers, so that you can reattach the antenna wire to a replacement card.
You can upgrade the card to this model...
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 original 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.
The cards normally do not come with an antenna.
You would need to order the antenna kit in chapter 3 of your notebook's service manual and you will need to completely disassemble the notebook, including the display panel area to properly route the antenna wire.
That is why I recommend you try and see if you can fix the wire.
Of course if the entire connector is broken off the wire, you will have no choice but to replace the antenna.
Below is the link to the service manual if you didn't use it to open up your notebook.

Well, here's an update! The new card was considerably larger (visually) than the original. However, it did slip into the motherboard connector. I experienced some trepidation at that point forward. At the top right are the pins, left one is where the old one broke off. While I waited for my caregiver to arrive, I double checked the existing antenna wire, and fortunately, the connector end of the wire was clear of any debris. I did not have to dissemble the Touch Screen. My fingers and eyes are pretty much garbage, so my angel arrived and her deft fingers (even with massive fingernails) and eagle eyes were able to snap the antenna back on to the new card, to the left of the #2 in the pic. What is the AUX pin for? Careful routing of the wire, and snap the case back together, and then functional test---------TA DA!!! Solid Wi-Fi signal!!
Uh Oh.... Now my Blue Tooth signal is horrid!! I have to lean my head/phones over my laptop to keep the signal from cutting out. Choppy for a few feet, then nothing. Do Wi-Fi and Blue Tooth use the same card/antenna?? Now what??
OLD CARD (sorry for fuzzy)

You didn't order the Realtek 8821CE wifi card I recommended.
You ordered the Intel 3165 which requires two wifi antenna wires be connected to it.
That is why the Bluetooth isn't working. There is no reception for the Bluetooth due to the missing antenna wire.
You needed to order this model card...there is only one antenna terminal to connect the antenna wire to and it works both the Wifi and Bluetooth.
This was the cheapest one I could find on the eBay listing.
I do see in that link of eBay listings I posted, that someone stuck the Intel 3165 AC in there by mistake.
Notice that there is only one antenna terminal to connect to just like the RTL8723DE card that you removed.

Aw, snap. Thanks again Paul. Maybe I need to take another look at the old card I have; perhaps what I thought was broken, isn't. I did buy this antenna, which as you can see is a dual wire arrangement. I'll keep it in case I need to do more surgery.
By the way, the p/n of the old wifi/bluetooth card is 915618-003

You're very welcome.
You could always buy a USB Bluetooth adapter and use then when necessary.
The dual band Intel card you installed is better than the Realtek one anyway.

Hmm, something has got me thinking here. If the old wi-fi card only has one antennae port, and the (much better) Intel replacement has two wi-fi antennae, would it be possible (theoretically speaking) to route the second antennae into the laptop somewhere? Obviously it would mean a lot of disassembly but it might be worth it to get a second antenna into the machine, thus allowing for working Wi-Fi & Bluetooth with a better wi-fi card?
