Dell OptiPlex 780 Wifi
It will be easier to buy a new wireless USB adapter and install it, than it is to replace any type of OEM adapter you might have. WiFi, or wireless internet, makes use of a wireless adapter in order to connect to your router and modem. Finding a WiFi adapter is easy due to the fact that all you need to know beforehand is the current operating system on your desktop. Most new Wifi adapters are simply plug and 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.
Major signs the WiFi adapter will need to be replaced
- Your wireless internet connection has trouble connecting during the day
- The desktop wireless driver gives errors when installing
- The WiFi adapter in your Dell desktop is unable to connect to the internet
