Review on Wuedozue RJ45 Network Splitter Adapter: 1 to 2 Dual Female USB to RJ45 Port for Simultaneous Online Connectivity - Cat6, Cat7 Compatible by Ron Coleman

Using Ookla's Speedtest, my download speed with the ethernet cable plugged directly into my iMac was 937 Mbps. With Wi-Fi only connection disabled, the speed was 404 Mbps. I purchased this item so I could take advantage of the higher speeds that come with plugging in my ethernet cable for my gaming and work computers. Download speed = 388 Mbps when I plugged my router into it and connected an ethernet cable to my iMac. So that. Yes - WiFi is the best option. This item becomes unusable.
