Dell Latitude C540 Wifi
Buying a USB wireless adapter is quick and painless because all you need to know is the operating system that is installed on your Dell laptop. You are better off buying a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. A lot of newer 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. The WiFi in your laptop, if so equipped, uses a piece of hardware in order to connect to your wireless router or modem.
Warnings your internal WiFi will need to be replaced
- The wireless adapter in your Dell laptop cannot see the SSID coming from your router
- Your WiFi signal has trouble connecting during the day
- The wireless adapter driver suddenly shows as uninstalled
