If you're tired of a weak Wi-Fi signal, the TP-Link range extender connects to your router without the need for cables, strengthening and extending its signal to areas it can't reach on its own. The device also reduces signal interference to ensure Wi-Fi coverage throughout your home or office. Press the WPS button on your router and the Range Extender button on your 850RE within 2 minutes to easily connect to the network. Once connected to an existing router, you can simply disconnect and connect the TL-WA850RE in one place for the best signal quality and coverage in your home, without having to configure the extender again. The TL-WA850RE's single Ethernet port allows the device to function as a wireless adapter to connect remote devices such as DVRs and TVs.
