The OptiPlex 755 did not ship with a wireless card. If you have installed a wifi card into one of the slots you can click the link below to setup the wireless network.
You can get a USB wireless dongle and use it to connect to the internet however Windows XP has reached End of Life and should no longer be used, its insecure and hasn't been patched in over a year. This system can run Windows 10 although its not strictly a free upgrade from Windows XP you can take the unofficial upgrade path using the Insider Preview 10130:

Ensure that you install Legacy BIOS A22 before proceeding with the upgrade:
