Chapter 1 Introduction This chapter provides an overview of the RoamAbout R1 and its features. Refer to the RoamAbout R1 SOHO Access Point Setup and Installation Guide for specification information.
Features You can connect the RoamAbout R1 to the Internet, or to a remote site, using its RJ-45 WAN port or RS-232 serial port. The RoamAbout R1 can also be connected directly to your PC, or to a LAN (local area network), using any of the three Fast Ethernet LAN ports or through the wireless interface. It can also function as a print server.
Access and Application Support Access and Application Support Many advanced applications are provided by the RoamAbout R1, such as: • Flexible LAN Access The RoamAbout R1 provides connectivity to 10/100 Mbps wired devices, as well as 11 Mbps wireless mobile users. The wireless interface makes it easy to create a network in difficult-to-wire environments, and to provide quick access to databases for wireless users.
Access and Application Support • Security The RoamAbout R1 supports security features that can deny Internet access to specified users, or filter all requests for specific services. The RoamAbout R1’s firewall can also block common hacker attacks, including IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding.
LAN Connections LAN Connections The three LAN ports on the RoamAbout R1 can auto-negotiate the connection speed to 10 Mbps Ethernet or 100 Mbps Fast Ethernet, as well as the transmission mode to half-duplex or full-duplex. These LAN ports also support auto-configuration for pin signals (auto-MDI/MDI-X) that allows you to use straight-through cable for connecting the RoamAbout R1 to any network device. Refer to the RoamAbout R1 SOHO Setup and Installation Guide.
Wireless Connections Wireless Connections Install a PC Card in each computer that will be connected to the Internet or your local network via radio signals. Rotate both antennas on the back of the RoamAbout R1 to the desired position. For more effective coverage, position one antenna along the vertical axis and the other along the horizontal axis. Place the RoamAbout R1 in a position that is located in the center of your wireless network.
Internet Connections Internet Connections If Internet services are provided through an xDSL or cable modem, use unshielded or shielded twisted-pair Ethernet cable (Category 3 or greater) with RJ-45 plugs to connect the broadband modem directly to the WAN port on the RoamAbout R1. Use either straight-through or crossover cable depending on the port type provided by the modem. For ISDN or PSTN service, attach the access device to the RS-232 serial port on the RoamAbout R1.
Chapter 2 Configuring the RoamAbout R1 A Web browser is used to configure the RoamAbout R1, view statistics, and to monitor network activity. The RoamAbout R1 can be configured by any Java-supported browser, including Internet Explorer Version 5.0 (or higher) and Netscape Navigator Version 4.0 (or higher). NOTE This manual assumes that you already set up the clients and installed the RoamAbout R1. If not, please refer to the RoamAbout R1 SOHO Access Point Setup and Installation Guide for instructions.
Access Web Management Access Web Management To access the RoamAbout R1’s management interface, enter the IP address of the RoamAbout R1 in your Web browser (http://192.168.2.1). The Login screen prompts you for a password. The default password is password. The Main page links are used to navigate to other pages that display configuration parameters and statistics. You can define system parameters, manage and control the RoamAbout R1 and its ports, or monitor network conditions.
RI Management Navigation Setup Page Description DNS Specifies DNS servers to use for domain name resolution. Wireless Configures the radio frequency, domain, and encryption for wireless communications.
Networking and Client Services Networking and Client Services Use the Setup page to configure the LAN interface (including TCP/IP parameters for the RoamAbout R1’s gateway address, DHCP address pool for dynamic client address allocation), the WAN connection options, DNS domain name mapping, the wireless interface, and other advanced services. You can use the Setup Wizard by clicking on the Start button at the bottom of the first page.
Networking and Client Services WAN Configuration Specify the WAN connection type required by your Internet Service Provider, then click on More Configuration to provide detailed configuration parameters for the selected connection type. Specify one of the first three options to configure a WAN connection through the RJ-45 port (i.e., a connection to an xDSL modem or Cable modem). Specify the Dial-up on Demand option to configure a WAN connection through the serial port (i.e.
Wireless Configuration Dial-up on Demand – Modem If you are accessing the Internet via an ISDN TA or PSTN modem attached to the serial port on the RoamAbout R1, then you must specify your account information as described below. • Check if you only use a dial-up modem to connect to the Internet. – If the serial port is used for primary Internet access, select this item. If not selected, then this connection will only be used for backup access if the primary WAN link fails.
Configuring Client Services Encryption If you are transmitting sensitive data across wireless channels, you should enable encryption. Encryption requires you to use the same set of encryption keys for the RoamAbout R1 and all of your wireless clients. The RoamAbout supports 40-bit or 128-bit WEP (Wired Equivalent Privacy) encryption. • The position of each key is important. The clients must enter the same key in the same position to communicate with the RoamAbout R1.
Configuring Client Services Network Address Translation – NAT Network Address Translation can be used to give multiple users access to the Internet with a single user account, or to map the local address for an IP server (such as Web or FTP) to a public address. This secures your network from direct attack by hackers, and provides more flexible management by allowing you to change internal IP addresses without affecting outside access to your network.
Configuring Client Services Enabling Special Applications Some applications require multiple connections, such as Internet gaming, videoconferencing, Internet telephony and others. These applications may not work when Network Address Translation (NAT) is enabled. Specify the port normally associated with an application in the Trigger Port field, select the protocol type as TCP or UDP, then enter the public ports associated with the trigger port to open them for inbound traffic.
Configuring Client Services MAC Filtering You can filter Internet access for local wired and wireless clients based on the MAC address. MAC Address Control Every client that connects to the network has a unique MAC (Media Access Control) address on his or her Ethernet adapter. An administrator can have more control- and more security- over the network by specifying which MAC addresses are allowed to access the RoamAbout R1. You can enable this feature by selecting Enabled.
Configuring Client Services When a wireless client is allowed to associate with the wireless LAN and connect to the RoamAbout R1, it has full access to the Internet and network resources.
Viewing Network and Device Status Viewing Network and Device Status The Status page displays the connection status for the WAN, WLAN, and LAN interfaces. It also displays the firmware and hardware version numbers, illegal attempts to access your network, as well as all DHCP clients connected to your network. The following information is displayed on the page: Field Description INERNET Displays connection type and status .
Appendix A Problem Solving This Appendix describes common problems you may encounter and possible solutions. The RoamAbout R1 can be easily monitored through its panel indicators to identify problems. Troubleshooting Chart Symptom Power LED is Off Action The External power supply has failed or is disconnected. Check connections between the RoamAbout R1, the external power supply, and the wall outlet.
Troubleshooting Chart Symptom Action Network Connection Problems Cannot Ping the RoamAbout R1 from the attached LAN, or the RoamAbout R1 cannot Ping any device on the attached LAN • • Wireless users cannot access the RoamAbout R1 Verify that IP addresses are properly configured. For most applications, you should use the RoamAbout R1’s DHCP function to dynamically assign IP addresses to any host on the attached LAN.
