Fujitsu LIFEBOOK C7661 Wifi
A lot of newer wireless adapters are simply plug and 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. WiFi, or wireless internet, uses an adapter to send and receive signals to and from your router and modem. Buying a USB wireless adapter is quick and painless because all you need to know is what OS you are running on your Fujitsu laptop. It is cheaper and easier to purchase a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have.
Warnings your internal WiFi is in dire straights
- The WiFi adapter driver gives errors when installing
- The wireless adapter on your laptop is unable to connect to the internet
- Your wireless internet connection goes in and out throughout the day
