Toshiba Qosmio G40 Wifi
It will be easier to buy a new USB adapter and install it, than to replace any built-in adapter your laptop may have. Buying a USB wireless adapter is quick and painless because the only thing you have to know is what OS you are running on your Toshiba laptop. The WiFi in your laptop, if so equipped, uses a piece of hardware to communicate with your router. Most new Wifi adapters are plug-n-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.
Clues of an inadequate wireless card
- The WiFi adapter on your laptop will not connect to your router anymore
- The wireless adapter driver shows it as not installed
- The WiFi disconnects itself during the day
