Usage
Designed for professionals, students, and home users who need wired connectivity in several locations, this splitter works perfectly in office desks, co‑working spaces, dorm rooms, and small conference areas. Simply plug the splitter into an existing Ethernet wall jack, then connect up to four devices such as laptops, desktop PCs, or network printers.
