It supports speeds up to 300Mbps on the 2.4GHz band, ensuring a stable connection for everyday browsing and streaming. Depending on your needs, you can use it as a repeater to boost a signal or as an access point via its 10/100Mbps Ethernet port to provide wireless connectivity to a wired device. Its compact white housing features two external antennas with MIMO technology to improve signal stability and coverage. A helpful color-coded LED indicator lets you know at a glance if the device is placed in the optimal spot for the strongest signal. For those who prefer mobile management, the Tether app allows you to configure settings and monitor your network from a smartphone. Security is handled through WPA2-PSK and other encryption standards to keep your data private. You can also manage energy use with the power schedule feature or refine who connects to your network using access control. This small device fits easily into any wall socket, making it a practical choice for homes or small offices where the main router cannot reach every room.
