Tired of Wi-Fi ''dead zone''? 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 2 minutes to easily connect to the network. 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. It's recommended that you choose a location where at least 3 signal light blue in order to guarantee a good performance. Range extenders. Transfer speed: N300. Wireless standards: b/g/n. Wireless.
