You've got one Ethernet port on the wall and three devices that need a wired connection. Or your Wi-Fi's been flickering again and you just want the cable to do its job. The EH310 splits that single run into three 1000Mbps ports. No config, no driver, no waiting for a tech to ring back. Plug it in, pick any port as your input, and the other three go live. The aluminium body keeps it cool under sustained load. Cat 5 through Cat 8 cabling all works with it. A USB-C power lead and a Cat 5e patch cable are in the box, so you're up before your coffee's done. Backward compatible down to 10Mbps if an older device needs a home
