TP-link RE450 AC1750 Wi-Fi Range Extender 

• Tired of Wi-Fi “dead zones”? The TP-Link AC1750 Wi-Fi Range Extender connects to your router wirelessly, strengthening and expanding its signal into areas it can’t reach on its own. 
• The RE450 delivers fast speeds of dual band Wi-Fi, providing reliable connections for bandwidth-intensive tasks like HD/4K streaming, lag free gaming, large file downloads.
• A gigabit Ethernet port turns the extender into a wireless bridge, letting you connect a wired device like a Blu-ray player, gaming console, DVR, or smart TV to your Wi-Fi network.
• Three external dual band antennas boost your wireless coverage and reliability, helping your devices stay connected anywhere your network reaches.
• High Speed mode maximizes overall performance by combining the bandwidth of both the 5GHz and 2.4GHz channels to create a lightning-fast connection with one band sending data and the other receiving it.
