Dell Inspiron 15 3551 Wifi
You are better off buying a new 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 system will install the drivers automatically. Finding a WiFi adapter is easy because all you need to know is the operating system that is installed on your Dell Inspiron 15 3551. WiFi, or wireless internet, uses a piece of hardware in order to connect to your router.
What red flags are there that my WiFi adapter is not working right?
- The laptop wireless driver suddenly shows as uninstalled
- The wireless adapter on your laptop is unable to connect to the internet
- The WiFi has trouble connecting throughout the day
