I am not a PC repair tech by trade or training.
I have given you the two possibilities...bad card...bad motherboard.
A bad card is cheap and easy to replace using the model I suggested.
A bad motherboard is expensive and hard to replace, and for a non-technical person, it would be better to buy a new notebook rather than try to do a major repair on an old notebook.
That is all the advice I can offer to you.

OK, this card will work with one antenna cable...
Realtek RTL8723BE 802.11bgn 1×1 + BT 4 LE Combo Adapter HP Part # 753077-001
This seller will ship the wifi card to India.
I could not find this part number on Amazon, India.
The antenna wire is not what is causing the wifi card to disappear.
If the antenna wire were bad, the card would still show up in the device manager.
It would just not have any reception.
