Dell OptiPlex 3030 Wifi
You are better off buying a new wireless USB adapter and install it, than to replace any built-in adapter your aio may have. 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 operating system will take care of the rest. Searching for a new adapter is simple because all you need to know is the current operating system on your Dell aio. The WiFi in your aio, if so equipped, uses a piece of hardware in order to connect to your home router.
Major warnings of a poorly performing WiFi adapter
- Your WiFi signal disconnects and reconnects during the day
- The WiFi adapter driver shows it as not installed
- The wireless adapter on your aio will not connect to your router anymore
