The WiFi Extender from D-Link broadcasts a signal on one frequency, 2.4Ghz, which offers lower speed compared to those that broadcast on 2 (dual) or 3 (tri-band) frequencies. The 2.4Ghz frequency is the most widespread, and as it has a long range, it is usually congested by neighboring Wi-Fi signals, further complicating device communication. For managing multiple devices, a dual-band device can handle it more effectively. The repeater can offer up to 300Mbps in total to the devices connected to it. In practice, the actual speed that such a repeater of this generation (Wi-Fi 4) can offer to a single device is closer to 50Mbps. Indicatively, a high-resolution 4K movie requires about 25Mbps. The speed that each connected device will have depends on the distance, obstacles, how many other devices are connected, how many other networks exist in the same space, etc. It is of Wi-Fi 4 generation, an older generation recommended for use with few devices and for applications that do not require high speeds. The connection via ethernet cable offers a speed of 100Mbps, which is sufficient to cover all needs, e.g., a high-definition 4K movie requires about 25Mbps.
