Dell Precision 420 Wifi
It will be easier to buy a new USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. The WiFi in your desktop, if so equipped, uses a piece of hardware to communicate with your router. Finding a WiFi adapter is easy because the only thing you have to know is the current operating system on your Dell desktop. A lot of newer wireless adapters are plug-n-play, in that you just plug it in the USB port and the system will install the drivers automatically.
Key signs of a poorly performing wireless card
- The WiFi adapter in your Dell desktop cannot see the SSID coming from your router
- The wireless adapter driver shows it as not installed
- Your wireless internet connection goes in and out all the time
