Product OverviewChapter 1Chapter 1:Product OverviewThank you for choosing the Wireless ADSL2 ModemRouter. This device lets you access the Internet via awireless connection or through one of its four switchedports. You can also use it to share resources such ascomputers, printers and files. A variety of security features,such as WPA2 security, a Stateful Packet Inspection (SPI)firewall and NAT technology, help to protect your dataand your privacy while online. Configuration is easy usingthe provided browser-based utility.Front PanelUSB (WAG320N only) (Green) The USB LEDlights up when a USB device is connected to theModem Router through the USB port.Wireless (Green) The Wireless LED lights upwhen the wireless feature is enabled. It flasheswhen the Modem Router is actively sending orreceiving data over the network.DSL (Green) The DSL LED lights up wheneverthere is a successful DSL connection. The LEDflashes green while the Modem Router isestablishing the ADSL connection.Internet (Green/Red) The Internet LED lights upgreen and stays on when a connection is madethrough the Internet port. It flashes to indicatenetwork activity over the Internet port. The LEDis lit red when an authentication error occurs.Back PanelPower (WAG120N: Green/Amber; WAG160N v2and WAG320N: Green/Red) The Power LEDis continuously lit green while the device ispowered on. The LED is lit amber (WAG120N)or red (WAG160N v2 and WAG320N) if a POST(Power On Self Test) failure or device malfunctionoccurs.Ethernet 1-4 (Green) These numbered LEDs,one for each of the numbered ports on theModem Router’s back panel, serve two purposes.If the LED is continuously lit, the Modem Router issuccessfully connected to a device through thatport. It flashes to indicate network activity overthat port.NOTE: The Ethernet 1 LED is lit amberwhen the WAN link is established on thatport.Wi-Fi Protected Setup Button (WAG120N:Green/Amber; WAG160N v2 and WAG320N:Green) Press this button to have Wi-Fi ProtectedSetup search for your Wi-Fi ProtectedSetup -supported wireless device. The LED iscontinuously lit green when a Wi-Fi ProtectedSetup connection is successfully established.The LED blinks slowly while Wi-Fi ProtectedSetup is setting up a connection, and is lit amber(WAG120N) or blinks rapidly (WAG160N v2 andWAG320N) if an error occurs. The LED is off whenWi-Fi Protected Setup is idle.DSL The DSL port connects to the ADSL line.Ethernet 4, 3, 2, 1 The Ethernet ports (4, 3, 2, 1)connect the Modem Router to wired computersand other Ethernet network devices.NOTE: The Ethernet 1 port canalso be configured as the WANport. To do this, access the Webbased utility (refer to “Chapter 3:Advanced Configuration” on page 4),then select the Setup Ethernet tab.USB (WAG320N only) The USB port connectsthe Modem Router to a hard drive or flashbased USB storage device.Reset There are two ways to reset the ModemRouter’s factory defaults. Either press andhold the Reset button for approximately fiveseconds, or restore the defaults from theAdministration Factory Defaults screen of theModem Router’s web-based utility.Power The Power port is where you will connectthe power adapter.On/Off Button Press the On/Off button to turnpower to the device on or off.NOTE: Wi-Fi Protected Setup is a featurethat makes it easy to configure yourwireless network and its security settings.Wireless ADSL2 Modem Router1

Product OverviewChapter 1Placement PositionsFollow these instructions:There are two ways to physically install the device. Thefirst way is to place the device horizontally on a surface.The second way is to mount the device on a wall.The best place for the device is usually at the center ofyour wireless network, within range of all of your wirelessdevices.Horizontal PlacementThe device has four rubber feet on its bottom panel. Placethe device on a level surface near an electrical outlet.Wall-Mounting PlacementThe device has two wall-mount slots on its bottompanel. The distance between the slots is 152 mm(6 inches).1. Determine where you want to mount the device. Makesure that the wall you use is smooth, flat, dry, andsturdy. Also make sure the location is within reach ofan electrical outlet.2. Drill two holes into the wall. Make sure the holes are152 mm (6 inches) apart.3. Insert a screw into each hole and leave 3 mm(0,12 inches) of its head exposed.4. Maneuver the device so the wall-mount slots line upwith the two screws.5. Place the wall-mount slots over the screws and slidethe device down until the screws fit snugly into thewall-mount slots.Two screws are needed to mount the device.4-5 mm1-1,5 mm2,5-3,0 mmSuggested Mounting Hardware††Note: Mounting hardware illustrations are nottrue to scale.NOTE: Cisco is not responsible for damagesincurred by insecure wall-mounting hardware.152 mmWall Mounting TemplateWireless ADSL2 Modem Router2

Wireless Security ChecklistChapter 2Chapter 2:Wireless Security ChecklistWireless networks are convenient and easy to install, sohomes with high-speed Internet access are adopting themat a rapid pace. Because wireless networking operates bysending information over radio waves, it can be morevulnerable to intruders than a traditional wired network.Like signals from your cellular or cordless phones, signalsfrom your wireless network can also be intercepted. Sinceyou cannot physically prevent someone from connectingto your wireless network, you need to take some additionalsteps to keep your network secure.1. Change the default wirelessnetwork name or SSIDWireless devices have a default wireless network nameor Service Set Identifier (SSID) set by the factory. This isthe name of your wireless network, and can be up to 32characters in length. Linksys by Cisco wireless productsuse linksys as the default wireless network name. Youshould change the wireless network name to somethingunique to distinguish your wireless network from otherwireless networks that may exist around you, but do notuse personal information (such as your Social Securitynumber) because this information may be available foranyone to see when browsing for wireless networks.2. Change the default passwordFor wireless products such as access points, routers, andmodem routers, you will be asked for a password whenyou want to change their settings. These devices have adefault password set by the factory. The default passwordis admin. Hackers know these defaults and may try touse them to access your wireless device and change yournetwork settings. To thwart any unauthorized changes,customize the device’s password so it will be hard toguess.3. Enable MAC address filteringLinksys by Cisco routers and modem routers give youthe ability to enable Media Access Control (MAC) addressfiltering. The MAC address is a unique series of numbersand letters assigned to every networking device. WithMAC address filtering enabled, wireless network accessis provided solely for wireless devices with specific MACaddresses. For example, you can specify the MAC addressof each computer in your home so that only thosecomputers can access your wireless network.Wireless ADSL2 Modem Router4. Enable encryptionEncryption protects data transmitted over a wirelessnetwork. Wi-Fi Protected Access (WPA /WPA2 ) andWired Equivalency Privacy (WEP) offer different levels ofsecurity for wireless communication.A network encrypted with WPA /WPA2 is moresecure than a network encrypted with WEP, becauseWPA /WPA2 uses dynamic key encryption. To protectthe information as it passes over the airwaves, you shouldenable the highest level of encryption supported by yournetwork equipment.WEP is an older encryption standard and may be theonly option available on some older devices that do notsupport WPA .General Network Security GuidelinesWireless network security is useless if the underlyingnetwork is not secure. Password protect all computers on the network andindividually password protect sensitive files. Change passwords on a regular basis. Install anti-virus software and personal firewallsoftware. Disable file sharing (peer-to-peer). Some applicationsmay open file sharing without your consent and/orknowledge.Additional Security Tips Keep wireless routers, access points, or modem routersaway from exterior walls and windows. Turn wireless routers, access points, or modem routersoff when they are not being used (at night, duringvacations). Use strong passphrases that are at least eight charactersin length. Combine letters and numbers to avoid usingstandard words that can be
