Rear Panel The rear of the router has the following connectors and controls:

Installing the Router RAC2V1A Router User Guide 11 1. Reset button: resets the router as if you power cycled the unit. Use a pointed non-metallic object to press this button and hold it for more than one second but less than five seconds. Note: If you hold the Reset button for more than five seconds, the router will be reset to the factory default settings and will restart. Do not perform a factory reset unless you expressly guided to do so by Spectrum customer service. 2. WPS Button: begins associating the router with a wireless device. 3. Ethernet (1 - 4): connectors for use with a computer LAN port or another Ethernet-connected device. 4. Internet: connector to the Spectrum modem. 5. USB: USB host connector for use with external USB devices. 6. Power: connector for the power cord. Selecting an Installation Location There are a number of factors to consider when choosing a location to install the router: • Is an AC outlet available nearby? For best results, the outlet should not be switched and should be close enough to the router that extension cords are not required. • Is the modem nearby? Can you easily run cables between the router’s location and the modem? • If you are connecting devices to the Ethernet ports, can you easily run cables between the router’s location and those devices? • If you want to install the router on a desktop, is there enough space on either side to keep the vents clear? Blocking the vents may cause overheating. • How close are the wireless devices? In general, the router should be located centrally within the premises, as close as possible to the location where users will want to access the wireless connection. The router wireless connection range is typically 100–200 feet (30m–65m) for 2.4 GHz signals and less for 5 GHz signals. A number of factors can affect connection range, as described below. Desktop Mounting Instructions Position the router so that: • Air flows freely around it

Installing the Router RAC2V1A Router User Guide 12 • The back faces the nearest wall • It will not fall to the floor if bumped or moved • The sides of the unit are not blocked. Factors Affecting Wireless Range A number of factors can affect the usable range for wireless connections. Increases range • Locating the unit centrally • Creating as much "line-of-sight" as possible with client devices Decreases range • Metal or concrete walls between the router and other client devices • Large metal appliances, aquariums, or metal cabinets between the router and other client devices • Interference and RF noise (2.4 GHz wireless phones, microwave ovens, wireless speaker/receiver systems, or other wireless networks) • Placing the router in a cabinet or other enclosed space • Placing the router next to a desktop computer Notes: • It may be acceptable to decrease the range of the wireless network, as long as the decreased range is sufficient for your needs. By limiting the network’s range, you reduce interference with other networks and make it harder for unwanted users to find and connect to the network. • Setting the transmit power level to High increases the range. Setting it to Medium or Low decreases the range. Medium or Low may be more appropriate for high-density residential locations. Ethernet or Wireless? There are two ways to connect the computer (or other equipment) to the router. The following will help you decide which is best for you: Ethernet Ethernet is a standard method of connecting two or more computers into a Local Area Network (LAN). You can use the Ethernet connection

Installing the Router RAC2V1A Router User Guide 13 if the client device has built-in Ethernet hardware. The router provides support for up to four such connected devices. Note: To connect more than four client devices to the router through the Ethernet ports, you need an Ethernet switch (available at computer retailers). The router includes one 3-foot (.9m) Ethernet cable. The enclosed Ethernet cable is yellow to match the Internet port on the back of the router, because this cable is primarily intended to connect the router to the Spectrum modem. You can purchase more cables if necessary at a computer retailer. If you are connecting the router directly to a computer, or to an Ethernet switch with a cross-over switch, ask for Category 5e (CAT5e) straight-through cable. CAT5e cable is required for gigabit Ethernet (Gig-E), not regular CAT5 cable. Wireless Wireless access lets you connect additional (wireless-capable) devices to the router. The 802.11 wireless LAN standard allows one or more computers to access the router using a wireless (radio) signal. These connections are in addition to the connections supported via Ethernet. Both If you have two or more clients, you can use Ethernet for up to four devices and wireless for the others. Connecting the Router 1. Unplug the power to turn off the modem. 2. Connect one end of the Ethernet cable (included) to the modem, and the other end to the Internet port on the router. 3. Reconnect the plug on the modem to turn the modem back on. Wait approximately 2 minutes to allow the modem to fully power up.

RAC2V1A Router User Guide 20 Advanced Configuration Options This section explains how to use the most common advanced configuration options for the router in the following areas: • LAN Setup • Wireless Setup • Firewall • Utilities Note: Refer to Router Configuration Screen Descriptions (page 28) for additional advanced configuration options. Configuring DHCP DHCP (Dynamic Host Protocol Configuration) is enabled by default on the router, which allows the router to act as a DHCP server and automatically assign an IP address to each device on the network. DHCP is a set of rules used by devices such as a computer, router, or network adapter to allow the device to request and obtain an IP address from a server, which maintains a list of addresses available for use. The DHCP server ensures that all IP addresses are unique, e.g., no IP address is assigned to a second device while the first device's assignment is valid (its lease has not expired). Without DHCP, the IP addresses must be entered manually at each computer or device and a new IP address must be entered each time it moves to a new location on the network. Configuring DHCP for IPv4 Perform the following steps to configure DHCP for IPv4. 1. Access and sign in to the configuration interface. 2. Click the LAN Setup tab. 3. Click LAN Settings (IPv4) in the side menu to display the LAN Settings screen. 4. Click the Enable DHCP Server checkbox under DHCP Server Settings.

DHCP Server Settings Enable DHCP Server Click this checkbox to enable the use of a Dynamic Host Configuration Protocol (DHCP) Server on the network. DHCP is a set of rules used by devices such as a computer, router, or network adapter to allow the device to request and obtain an IP address from a server which maintains a list of addresses available for use. The DHCP server ensures that all IP addresses are unique, e.g., no IP address is assigned to a second device while the first device's assignment is valid (its lease has not expired). Without DHCP, the IP addresses must be entered manually at each computer in an organization, and a new IP address must be entered each time a computer moves to a new location on the network. Start IP Address/End IP Address Enter the range of IP addresses that the DHCP Server will be allowed to assign to a network device. Lease Time Select the time before the assigned IP address will expire. (After the lease time is up, the user is automatically assigned a new dynamic IP address.) A "lease" is the amount of time that a given IP address will be valid for a computer or other network device. The lease time can vary depending on how long a user is likely to require the Internet connection at a particular location. Using very short leases, DHCP can dynamically reconfigure networks where there are more computers than available IP addresses, such as educational environments. Domain Name Enter the domain name that you want to display on client devices.

RAC2V1A Router User Guide 89 Troubleshooting The router is plugged in, but the light is off Check all power connections. Is the power cord plugged in firmly at both ends? If you plugged the power cord into a power strip, make sure the strip is switched on. Try to plug the power cord into a different outlet. If the outlet is controlled by a wall switch, make sure the switch is on. Finally, check the fuse or circuit breaker panel. I'm not getting on the Internet (all connections) It may take several minutes to establish a connection the first time you power up the router, especially when many people are online. Always leave the router plugged into AC power and connected to the modem. Check the light on the front. It should be blue. Check the cable connections. Connectors should be tight. Cables should not be pinched, kinked, or bent sharply—any of these can cause a break or short in the cable. (You may have to replace the cable). Proceed to the Ethernet or wireless solutions if necessary. I'm not getting on the Internet (Ethernet) If you are using a switch, is the switch turned on? Are you using the right type of Ethernet cable? Use an RJ45 Cat5e cable for direct connection to a computer; use a cross-over cable for connection to a switch. Unplug the power from the router and wait a few seconds, then plug the power back in. A misconfiguration could lock out all access to the router. If you think this has happened, see Factory Defaults (page 82). I'm not getting on the Internet (Wireless) Check the light on the front. It should be blue. Does the connection utility discover your wireless LAN? If you turned off “Broadcast Wi-Fi Network Name (SSID)” you need to manually enter the name of the wireless LAN in the connection utility.

Troubleshooting RAC2V1A Router User Guide 90 Change the security setting to another setting. A misconfiguration could lock out all access to the router. If you think this has happened, see Factory Defaults (page 82). Make sure that your wireless device is compatible with the wireless mode that you selected. See Setting the Wireless Mode (page 22). My wireless Internet connection stops working sometimes This may be caused by distance or interference. Try moving the device closer to the router. Two common sources of interference are 2.4 GHz “remote” telephones and microwave ovens. If you cannot remove the interfering product, try using a different channel. I can get on the Internet, but everything is slow If the Web site you are visiting is very popular, that site may be having trouble servicing all the requests. If other sites download quickly, wait for a few minutes and try again. Web site traffic during peak hours may also affect the connection speed. Other communications on the LAN, or interference with wireless connections, may slow down the connection.
