WiFi, or wireless internet, makes use of a wireless adapter in order to talk to your router. Buying a wireless adapter is quite easy because the only thing you have to know is the current operating system on your laptop. It will be easier to buy a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. Most USB wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will install the drivers on its own.
What symptoms are present when the wireless card is almost dead?
- The wireless signal goes in and out all the time
- The WiFi adapter on your laptop cannot see the SSID coming from your router
- The laptop wireless driver suddenly shows as uninstalled
