Dell OptiPlex 9020 Wifi
Most new Wifi adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will handle everything from there. The WiFi in your aio, if so equipped, uses a piece of hardware in order to connect to your home router. Finding a WiFi adapter is easy due to the fact that all you need to know beforehand is what OS you are running on your Dell aio. 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.
Key symptoms of a poorly working WiFi adapter
- The wireless adapter in your Dell aio is unable to find a signal from your router
- The WiFi adapter driver suddenly shows as uninstalled
- The wireless signal has trouble connecting during the day
