Most laptops have an Ethernet port that you can use to connect to a wired network. If you want to share your laptop's Internet connection with other devices, you can do so by connecting them to your laptop with an Ethernet cable.
To share your Internet connection, you'll need to enable Internet Connection Sharing (ICS) on your laptop. Once ICS is enabled, your laptop will act as a router and provide Internet access to any connected devices.
Keep in mind that sharing your Internet connection will reduce your overall bandwidth. So if you're already pushed for speed, sharing your connection may not be the best idea. But if you have a fast connection and want to help out other devices in your home or office, sharing your Internet is a great way to do it!
