Review on Ethernet Splitter Adapter 1 to 2 Female Socket, ToneGod RJ45 Extender 🔌 Plug LAN Network Connector, Compatible with Cat5, Cat5e, Cat6, Cat7 Ethernet Cables (4 Pack) by Brett Zhu

These connectors are not needed if you plan to connect two different devices and use them at the same time. You will not! I ran a 20 foot cable straight from the modem to the splitter, then 3 feet to the computer and another 3 feet to the phone system. I was able to get a signal on the phone, but the computer that was supposed to be getting 100Mbps from the Spectrum was only getting 12Mbps, which I believe was coming from our wireless connection, not the cable. Don't buy if you want to pair devices together. I returned and returned the money.
