Dell OptiPlex 390 Wifi
Most new Wifi adapters are simply plug and play, in that you just plug it in the USB port and the OS will handle everything from there. Buying a USB wireless adapter is quick and painless because the only thing you have to know is the operating system that is installed on your Dell OptiPlex 390. You are better off buying a new USB adapter and just plug it in, than to replace any built-in adapter your desktop may have. WiFi, or wireless internet, uses an adapter to send and receive signals to and from your router and modem.
Red flags the WiFi adapter is in need of replacing
- The wireless adapter in your Dell desktop does not connect at all
- The wireless adapter driver cannot be installed
- Your wireless internet connection drops multiple times every day

Dell OptiPlex 390 WiFi is best purchased new due to the wear on an older one. It is in your best interest to note the model number before placing an order for a new WiFi. Try to always buy computer parts from a known seller when buying via the internet. Your Dell desktop will love you more if you buy smart!
