Dell P07T Wifi
It is much simpler to buy a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is what OS you are running on your laptop. The WiFi in your laptop, if so equipped, uses an adapter to send and receive signals to and from your home router. A lot of newer wireless adapters are simply plug and play, in that you just plug it in the USB port and the OS will handle everything from there.
Clues to watch for to know your internal WiFi will need replacing
- The WiFi adapter on your laptop cannot see the SSID coming from your router
- The wireless adapter driver suddenly shows as uninstalled
- The wireless signal drops multiple times throughout the day
