If you need to improve your wireless coverage to eliminate "dead zones" in your home or office network, a range extender might be the one to look for. It will easily increase the range of your current wireless route and network. A wireless range extender increases the distance over which a WLAN signal can spread, overcoming obstacles and enhancing overall network signal quality. A wireless range extender works as a relay or network repeater, picking up and relecting WiFi signals from a network's base router or access point.
TP-LINK's TL-WA850RE is designed to conveniently extend the coverage and improve the signal strength of an existing wireless network. With 300Mbps wireless N speeds, Range Extender button, miniature size and wall mounting design, extending a wireless network has never been easier. What's more, its Ethernet port allows the TL-WA850RE to act as a wireless adapter to turn a wired device into a wireless one.
