Tired of Wi-Fi ’’dead zones?" TP-LINK’s range extender connects to your router wirelessly, strengthening and expanding its signal into areas it can’t on its own. The device also reduces signal interference to ensure reliable Wi-Fi coverage throughout your home or office. The TL-WA850RE’s single Ethernet port allows the extender to function as a wireless adapter to connect wired devices like Blu-ray players, gaming consoles, DVRs and Internet TVs. At the same time, the device can share the wireless network as well. 5 signal lights show the strength of signal that TL-WA850RE receives from the existing router, which can help to find the right location to place the range extender. Use any mobile device to easily access and manage various features, including the LED control function's Night Mode, which allows you to enjoy a more peaceful night's sleep.
