TP-LINK TD-W8970B

Multipurpose device for internet ADSL2 + and quick sharing via cable and air. It represents an excellent solution for home users who want throughout your home internet connection through divorce Gigabit Ethernet or stable WiFi, which has now 3 antennas caring for the strong coverage . This makes it possible to access higher speeds and from further afield. Function QoS effectively allocates internet evenly among all users and use a data-intensive activity vulnerable to interruption Such as HD video streaming, VoIP telephony or playing online games.
Two USB 2.0 ports, multi-function users can share files between multiple devices and computers on your home network, or through FTP server in the public network, so you'll have your files are always available. If you own a printer that does not have a port to connect to a network or WiFi wireless technology, USB port lets you print to it from any computer on the network. More advanced users deliver support IPsec VPN tunnels for the That will bring a remote connection to a private network, and secure access to the same data as the local user. Supported by the 10 VPN tunnels .
