There are a few ways to download a WiFi driver for a laptop that does not have WiFi:
# ***Use an Ethernet cable.*** If your laptop has an Ethernet port, you can connect it to a router using an Ethernet cable. This will give you internet access, which you can then use to download the WiFi driver.
# ***Use a USB WiFi adapter.*** If your laptop does not have an Ethernet port, you can use a USB WiFi adapter to connect to the internet. USB WiFi adapters are relatively inexpensive and can be purchased from most electronics stores.
# ***Download the WiFi driver on another computer.*** If you have another computer with internet access, you can download the WiFi driver on that computer and then transfer it to your laptop using a USB drive or SD card.
Once you have downloaded the WiFi driver, you can install it on your laptop by following the instructions provided by the manufacturer.
