Dell Precision M6400 Wifi
You are better off buying a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have. Searching for a new adapter is simple because all you need to know is what OS you are running on your laptop. The WiFi in your laptop, if so equipped, uses a piece of hardware to send and receive signals to and from your router and modem. Most USB wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the system will install the drivers automatically.
Indications to watch for in a failing wireless internet adapter
- The wireless adapter driver gives errors when installing
- Your WiFi in your Dell laptop will not connect to your router anymore
- The wireless signal drops for no reason during the day
