Dell Latitude E7250 Wifi
It is cheaper and easier to purchase a common WiFi USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. The WiFi in your laptop, if so equipped, uses a piece of hardware to send and receive signals to and from your router. A lot of newer wireless adapters are plug-n-play, in that you just plug it in the USB port and the OS will install the drivers on its own. Buying a wireless adapter is quite easy because the only thing you have to know is the operating system that is installed on your laptop.
Main clues your internal WiFi needs replacing ASAP
- The wireless adapter driver shows it as not installed
- The WiFi adapter in your Dell laptop will not connect to your router anymore
- The wireless signal goes out randomly every day
