I have been experiencing a similar issue, more on what my router shows on this thread, if there is a solution, I would be very happy.
Also, if possible, please explain further the problem and solution, I think everyone here wants to learn more, and it's always a good thing to understand what you are doing.

on my router it was the standard 12V plug that comes with this sort of devices, 5.5mm outer diameter
has anyone tried this eeprom image? my device still presents problems with the openwrt snapshot.
I followed @gwlim instructions and the wifi range is noticeably better now. And new power levels appeared for 5GHz, up to 23dBm.
Can you elaborate? I did a live dump and the said lines are already there (19.07.4), do I need to delete them or smth?
Left is the dumped EEPROM from my Newifi D2, right is after the modification.
May I ask what tx power values you've got? These are mine:
2,4GHz
5GHz
Although I doubt they are real.
Both my 2.4 and 5 ghz go up to 20dBm
interesting, can you run this command iwinfo wlan0 txpowerlist for me please?
sadly, nothing changed, and I forgot to backup the one that came with my device, so no idea as to the actual difference that would have made.
There is another radio eeprom in this google drive zip file that you can try. I found that it did help my wireless performance, but I still have problems with the switch crashing.
Mine came with that eeprom flashed and the wifi performance was poor. Looks like this is better. Also, I found some Chinese eeproms https://aisoa.cn/post-2439.html, haven't tried yet.

If I create several networks in the 5ghz one falls and the others stay, this cannot be the driver, if they do not fall all at once
Could you post your eeprom bin?
when I leave 2.4ghz on channel 1, 5 ghz is more stable.
here is the firmware information
note: 5ghz on channel 44 to 80mhz
achieve stability with channel 36 to 80 mhz (5 ghz to 40 mb / s) and 2.4 ghz channel 1 to 40 mhz, yes it is not 100mb / s on wifi 5. would this be possible?
or would the wifi driver of the notebook limit the speed, use in the same router comfort?
i have solved all my wifi problem with this eeprom on both my two newfi D2! Thank you @motocrossmann !
try channel 36 I thought it best
