Dell Vostro A840 Wifi
The WiFi in your laptop, if so equipped, uses an adapter in order to talk to your home router. 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 due to the fact that all you need to know beforehand is the operating system that is installed on your Dell laptop. Most USB wireless adapters are plug-n-play, which means you simply plug it into a USB port and the OS will handle everything from there.
Red flags the WiFi adapter has very little life left
- The WiFi adapter in your Dell laptop cannot see the SSID coming from your router
- The WiFi drops multiple times all the time
- The laptop wireless driver cannot be installed
