Fujitsu LIFEBOOK E8420 Wifi
Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is the operating system that is installed on your Fujitsu laptop. The WiFi in your laptop, if so equipped, makes use of a wireless adapter in order to connect to your router and modem. A lot of newer wireless adapters are simply plug and play, which means you simply plug it into a USB port and the system will install the drivers automatically. You are better off buying a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have.
Major symptoms your internal WiFi needs a replacement ASAP
- The WiFi adapter driver shows it as not installed
- The WiFi adapter on your laptop does not connect at all
- Your wireless internet connection drops multiple times throughout the day
