Sorry to beat an old hoarse to death, but I am having a lot of troubles with my Realtek RTL8188EE 802.11 b/g/n Wi-Fi Adapter. Read most of the articles and helps, spent over 200 hours and to keep it short I have decided to change the piece.
I have a Pavilion 17-f121ds and the card in it has the HP P/N 709505-001, MO:202015366-04. I only have one antenna lead (black) so I know I will need to upgrade the antenna also.
Since I have to change this one I wanted to upgrade to a 2.4 / 5 GHz possibly with Bluetooth but not a must since I am not sure the benefit on a laptop. After some searching I realized that with 6E already available in the USA I might as well go all the way and include it also so I came up with this: Wi-Fi 6E Mini PCI-E WiFi Netzwerkkarte MPE-AXE3000H 2,4GHz 5GHz 6GHz 5400Mbps Wireless Card BT5.2 80...

As you have discovered, the problem is your notebook only has one Wi-Fi antenna wire and any dual band HMC Wi-Fi form factor card will need two in order to work properly.
Also, it is very possible that an Intel based Wi-Fi card will not work in an AMD notebook that old, which I am pretty sure all of those type HMC AX Wi-Fi cards card use an Intel Wi-Fi chipset.
If you are going to add a second antenna wire, I think this would be the best card you can upgrade to:
Broadcom BCM4352 802.11ac 2x2 Wi-Fi + Bluetooth 4.0 combo HP part # 724935-001
The card will have a maximum throughput of 867 MBPS on the 5.0 GHz wifi band.
