Dell N5050 wireless card upgrade.

Hello there I’m using Dell N5050 model since last 10 years and it’s working fine but recently I’m facing Wi-Fi connection drop issues with it and tried everything at software levels (even formatted laptop) but that didn’t fixed my issue so I’m thinking the wireless card is faulty.

I’ve tried to look up wireless card for my Dell N5050 model but not sure whether below will work on my laptop, please confirm and let me know so I can buy it online.

1) Intel Network 7260 Wi-Fi card:
