Do I have Wi Fi?
Computers include expansion slots that allow users to add new devices to their computers. A computer player, for example, may upgrade their video card to improve gaming performance. They can use an expansion slot to swap out the old video card with a new one without having to replace the motherboard. What are the advantages of having expansion slots? A computer's expansion slots can be used to install network cards. If the computer does not already have a Wi-Fi adaptor, a Wi-Fi network card can be installed. Furthermore, as newer, faster Wi-Fi standards are announced, expansion card Wi-Fi adapters can be swapped out for newer, faster cards.
If there are no Wi-Fi routers around, then you cannot get Wi-Fi.
