CHAPTE 2. OVE VIEW
General Information
DSL-2650U/NRU is a multifunction 3G/ADSL/Ethernet router ith Wi-Fi and built-in s itch. The
router allo s accessing the Internet via 3G GSM net ork ( ith a 3G USB modem1,2 connected). In
addition, the device allo s accessing the Internet via ADSL technology and via Ethernet
technology.
The router is equipped ith an ADSL port to connect to an ADSL line and 4 Ethernet ports to
connect orkstations. Due to this feature, DSL-2650U/NRU represents a moderate-priced solution
for creating ired net orks ithout an additional s itch. In addition, any Ethernet port of the
device can be used to connect to a private Ethernet line. Also the router has a USB port designed
to connect a USB modem, printer, or USB storage.
DSL-2650U/NRU is equipped ith an integrated 802.11n draft* WLAN interface and is
compatible ith 802.11b/g ireless devices. The router supports multiple functions for the
ireless interface: several security standards (WEP, WPA/WPA2), MAC address filtering, and the
WPS function.
The ireless router DSL-2650U/NRU includes a built-in fire all. The advanced security
functions minimize threats of hacker attacks, prevent un anted intrusions to your net ork, and
block access to un anted ebsites for users of your LAN.
You can configure and manage the settings of DSL-2650U/NRU via the user-friendly eb-based
interface (the interface is available in t o languages – in English and in Russian).
