Toshiba Satellite S40DT-B Wifi
You are better off buying a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. Finding a WiFi adapter is easy because the only thing you have to know is the current operating system on your Toshiba Satellite S40DT-B. 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. The WiFi in your laptop, if so equipped, makes use of a wireless adapter to send and receive signals to and from your router and modem.
Symptoms of a bad onboard WiFi
- The wireless adapter driver cannot be installed
- Your WiFi on your laptop is unable to find a signal from your router
- Your WiFi signal drops multiple times all the time
