In order for anyone to provide you with assistance, you will need to post an inxi output here as the proper chipset for that adapter will need to be identified to find the driver. Sometimes manufacturers change the chipset for a particular model as well. Please read:
I posted the CPU information due to a direct request to post my inxi output. What instructions did I follow? After 5,000,000 you tube videos I finally found one that walked me through step by step the driver update and it finally worked.
Here is the lsusb info, and as you can see Bus003 Device002 it is there with the correct driver, now to just get it activated, I will check out the link you provided above, thank you.
I have another Mojave 10.14.6 install which does not suffer from this issue, both Catalina and Mojave running using same opencore 0.5.7 EFI, so I suspect it is related to TPLINK driver TL-WN725N(UN)_V3_191229_Mac 10.15 (which is also used on both Mojave and Catalina)
Just search for adapters that are well supported in GNU/Linux. You will probably need to figure out the chipset. There are only a handful of chipsets that have fully free/open drivers available, but these will be the best supported (some times right out of the box in Linux without needing anything).
There are V1, V2 and V3 of Tl-WN725N, TP-Link released Linux driver code for V3, and there is manual on how to install drivers on Linux, read it. (And you want to install kernel header through `sudo armbian-config` first)
