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. Press the WPS button on your router and the Range Extender button on your 850RE within minutes to easily connect to the network. Once connected with an existing router, you can simply unplug and plug the TL-WA850RE back in a location for the best signal quality and coverage in your house, without needing to configure the extender again. The TL-WA850RE’s single Ethernet port allows the Extender to function as a wireless adapter to connect wired devices like gaming consoles, DVRs and Internet TVs. At the same time, the device can share the wireless network as well.
