Read the above, covers the topic, if you want specific help we need exact info about what you have currently, not generalities.
Not too keen on networking, although i had both at one time, when using XP. I presume i do not have to tell you how i have my wireless hooked up...but its the usual as far as I know...router to cable modem...
.ethernet from modem to pc. I am using a usb DLink for my wireless. I also have another nic which came with Windows. Is that specific enough? Oh, I also have Win 7 and win 10, but primarily use Win 7, if that should matter.
Sounds like you already have a wired connection, though maybe used the terminology wrong.
The internet comes from your ISP to the Modem (cable/DSL) in your home, the modem connects via an ethernet cable to your Router (which may be a Router/Modem combo if provided by your ISP, key indicator would be having multiple ethernet ports on it, like 3+) Then your PC is connected to the router via an ethernet cable.
The router directs the traffic from your computer to the modem or to other computers connected to your router.
So if you already have a wired connection, what are you trying to do?
