תאור

ADSL- port and 4- port switch
ADSL- router has a port for connecting to ADSL- line. Built-in 4 - port switch allows you to connect computers equipped with Ethernet- adapters , game consoles and other devices to your network . In addition, any Ethernet- port devices can be used to connect to a dedicated Ethernet- line.
 
Wireless Interface
You can quickly create a wireless network at home or in the office , which will allow your employees or members of your family to connect to a wireless network almost anywhere (within range of a wireless network.) The Router can serve as an access point to connect to the wireless network devices of the standards 802.11b, 802.11g and 802.11n.
The device supports several security standards (WEP, WPA/WPA2), filtering devices to be connected to MAC- address , and allows the use of technology WPS.
In addition, the device is equipped with a button to disable / enable the Wi-Fi- network. In case of need , such as leaving home , you can turn off the router's wireless network at the touch of a button, while
devices connected to the LAN- ports on the router will remain in the network.
