This is from dictation.
Here is what I think is a quick way to solve your problem. I am going to assume that you're using the Wi-Fi router and there is nothing wrong with the router itself. Apparently you are somehow able to get to the Internet with either another of computer or another operating system. Your problem is that you cannot get an Internet connection using Windows 10. Is that so? I would assume that it is.
What you could do is purchase one of those people Wi-Fi USB adapters that are sold on Amazon and other sites. Practically all of these adapters are compatible with Windows 10 and Windows 10. Install a suitable driver automatically.
You might get a small CD with the unit, and if so, it will have a suitable driver for Windows 10. But the driver supplied by Windows 10 might be good enough to give you a usable Internet connection.
Once you have a suitable Internet connection, you can search for a better driver for your Wi-Fi adapter. Or just continue to use the new Wi-Fi adapter and forget about the old one.
What I'm trying to say is this; the new Wi-Fi adapters are so cheap and universal that is almost not worth your time to try to figure out when older unit is not working right. That is especially true with the drafters that have the brand Realtek. That particular brand is give me more trouble than I can mention. However, the newer versions of that same chipset company seem to work alright.
Anyway, I think that's the easiest and quickest way to solve your problem.
End of dictation.
