Fujitsu LIFEBOOK E6644 Wifi
The WiFi in your laptop, if so equipped, makes use of a wireless adapter to send and receive signals to and from your home router. It is cheaper and easier to purchase a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Finding a WiFi adapter is easy due to the fact that all you need to know beforehand is what OS you are running on your Fujitsu laptop. A lot of newer wireless adapters are simply plug and play, which means you simply plug it into a USB port and the OS will install the drivers on its own.
Red flags the wireless card is in need of replacing
- The laptop wireless driver suddenly shows as uninstalled
- The wireless adapter in your Fujitsu laptop will not connect to your router anymore
- Your wireless internet connection drops for no reason during the day
