It is cheaper and easier to purchase a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have. 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. WiFi, or wireless internet, uses a piece of hardware to communicate with your home network. Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is the current operating system on your laptop.
Major symptoms to watch for in a failing WiFi adapter
- Your WiFi in your Dell laptop will not connect to your router anymore
