DSL-2750UEOL EOS
תאור
DSL-2750U/NRU/C - a universal 3G/ADSL/Ethernet-marshrutizator with Wi-Fi and built-in switch. The router lets you connect to the Internet via 3G GSM with 3G USB-modema1, 2. In addition, the device provides a high-speed Internet access technology like ADSL, and technology Ethernet.
The router is equipped with ADSL-port for connecting to the ADSL-line and 4 Ethernet-ports for connecting workstations. With this DSL-2750U/NRU/C is an economical solution to create a wired network and eliminates the need to install a separate switch. In addition, any Ethernet-port devices can be used to connect to a dedicated Ethernet-line.
Also, the router has a USB-port for the USB-modem, printer, or USB-drive. DSL-2750U/NRU/C equipped with wireless 802.11n * standard interface and is compatible with 802.11b standard wireless devices and g as well.
The Router provides many functions for the wireless interface. The device supports several security standards (WEP, WPA/WPA2), filter plug-in device MAC-address, and allows the use of technology to WPS.
DSL-2750U/NRU/C router provides firewall. Enhanced security features allow you to minimize the effects of hackers and prevent intrusion into your network and access to undesirable Web sites for users on your LAN.
To manage and configure DSL-2750U/NRU/C used a simple and convenient built-in web-based interface.
1. USB-modem is not included. D-Link is not guaranteed compatibility with all USB-modems. See Supported USB-modem in the user guide on page 108.
* Maximum wireless speed is limited to 200 Mbps.
