Ethernet 1 to 3 Splitter This product is not a switch and does not allow three computers to share the internet connection simultaneously. Only one output port can be active at a time. Compatibility: This 1 to 3 RJ45 Ethernet splitter helps reduce cable clutter and prevents cable damage. It is compatible with ADSL, hubs, switches, TVs, set-top boxes, routers, wireless devices, and computers. Supports Cat5, Cat5e, Cat6, and Cat7 cables. Excellent Connection and Transmission Performance: The splitter features a gold-plated connector core, metal shielding, and a fixed RJ45 interface. It provides protection against electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring stable and reliable signal transmission. Best Design: Ideal for users who frequently move a laptop between three different rooms. This splitter eliminates the need to repeatedly unplug and reconnect network cables, providing convenient access to a wired network connection in multiple locations. Note: When connecting to multiple devices, only one device can be active on the network at a time. To switch between devices, disconnect the inactive device either through network settings or by physically unplugging the cable. Failure to do so may result in connection conflicts.
