Hi. I'm new to the Linux OS. I have the same problem as you do but with a RealTek d723. I did all the steps in the video (https://youtu.be/MbrYpqHadVQ) but what has helped me is step 8. I too had a weak signal as well as drop signals. Step 8 allows me to switch to a different frequency or antenna and brings me up to a decent speed of 72 Mb/s which I think is the max for the RealTek d723 wireless card. Step 8 is sudo modprobe -r rtl8723de && sleep 5 && sudo modprobe rtl8723de ant_sel=2. By the way, I've had to use step 8 each time I boot up and sometimes more than once in each boot but the second time is a charm. This is just a suggestion and I hope it helps.
