Add a Gigabit network port to your computer, using a USB (Universal Serial Bus) Type-C connection. The RJ45 port supports multiple speeds (10/100/1000 Mbps) & is fully compatible with Cat 5 [and higher] cabling. This is an essential peripheral for new laptops that lack an Ethernet port. In addition, it can be utilized or whenever Wi Fi is unavailable or when wireless network speeds are inconsistent.
