Dell Inspiron M5040 Wifi
The WiFi in your laptop, if so equipped, makes use of a wireless adapter in order to talk to your router and modem. 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 Dell laptop. It will be easier to buy a new USB adapter and install it, than it is to replace any type of OEM adapter you might have. Most USB 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 operating system will take care of the rest.
Subtle hints the wireless card has little time left
- The wireless adapter driver suddenly shows as uninstalled
- The wireless adapter on your laptop cannot see the SSID coming from your router
- The WiFi disconnects itself throughout the day
