Random disconnections, cannot delete NetworkProfile

[dniosaur]

I have this TL-WN781ND adapter which I got since 2016 but It has this problem that it randomly disconnects itself from the internet, sometimes with an exclamation mark, showing a 1-bar or showing full-bar (even if its not working)
I made a bat file with this code:
echo off
cls
ipconfig /release
ipconfig /renew
ipconfig /registerdns
exit
I also ticked connect automatically on my internet but that doesnt seem to work
I reinstalled drivers too.
Another problem of mine is I have 2 internet profiles, 1 named as my original internet and the other as NetworkProfile that always reappears everytime I delete it.

Sorry for my punctuation mark and grammar errors but I just really want to fix this it's been a year.

Did you check for newer drivers? Test it with another computer? Other wireless devices work normally in the same area? Try another adapter?

I already have the newest driver
I don't have another computer to test it on
All other devices works perfectly
I don't have the money to buy another

If everything is good on your router aside from this one card, I'd say the card is bad. Which is why you need to test it on another system to verify. If it works somewhere else, then it's an not a bad card and can check other things.
