The TL-WR543G has 2x to 3x eXtended Range WLAN transmission technology, so that transmission distance is 2 to 3 times traditional 11g/b range. This range tested at 855.36 meters. The built-in NAT and DHCP server (supporting static IP address distributing) provides changeable access control. For security purposes, the TL-WR543G has a feature that shuts off the SSID broadcast, so that only those with your network name can use the network. This router is a step up from the lower cost TL-WR541G in that it supports Wi-Fi, has a 4-port switch, and has AP Client Router and AP Router operation modes. The TP-Link TL-WR543G 54Mbps wireless router comes with an Easy Setup CD.
