In the Wireless AP + Cable/DSL Router, you can check these settings by going to the Basic Setup screen. 2. The Diag LED stays lit when it shouldn’t. • The Diag LED lights up when the device is f irst powered up. Meantime, the system will boot up itself and check for proper operation. After f inishing the checking procedure, the LED turns off to show the system is working f ine. If the LED remains lit after this time, the device is not working properly. First, try restoring the Wireless AP + Cable/DSL Router’ to it’s default settings by hold- ing down the Reset button for more than f ive seconds. If the LED remains on after restoring the default settings, try to re-flash the f irmware by assigning a static IP address to the computer, then upgrade the f irmware again. If that does- n’t help, contact your dealer for further information. 3. I can’t browse through the Wireless AP + Cable/DSL Router. • Make sure that both ends of the network cable and power adapter are properly connected and that the status LEDs on the front panel are func- tioning properly. • If using Windows 95 or 98, check the TCP/IP setup on the client side. Run winipcfg by clicking on the Startbutton, then selecting Run. The PC should have an IP address of 192.168.1.xxx (xxx is from 2 to 254.) Network Mask is 255.255.255.0, the default gateway IP should be the Router’s IP Address.
64 63 Etherfast ®Wireless AP + Cable/DSL Router with PrintServer Does the Wireless AP + Cable/DSL Router support any operating system other than Windows 95, 98, Millennium, NT, or 2000? The Wireless AP + Cable/DSL Router’s Web Utility is conf igured via the Internet web browser on your Linux system. The PrintServer, though, is conf igured through Windows and will not function under Linux. Linksys does not, at this time, provide techni- cal support for setup, conf iguration or troubleshooting of any non-Windows operating systems. Does the Wireless AP + Cable/DSL Router support ICQ send file?Yes, with the fol- lowing f ix: ICQ menu-> preference -> connections tab-> check I am behind a f irewall or proxy, and set the f irewall time-out to 80 seconds in f irewall setting. The Internet user can then send a f ile to a user behind the Wireless AP + Cable/DSL Router. I setup an Unreal Tournament Server, but others on the LAN cannot join. What do I need to do? If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the LAN computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. If you want to use the UT Server Admin, forward another port (8080 usually works well), then in the [UWeb.WebServer] section of the server.ini f ile, set the ListenPort to 8080 (to match the mapped port above) and ServerName to the IP assigned to the Router from your ISP. How do I get Half-Life: Team Fortress to Work with the Wireless AP + Cable/DSL Router?The default client port for Half-Life is 27005. The computers on your LAN need to have +clientport 2700x to the HL shortcut command line; the x would be 6, 7, 8, and on up. This lets multiple computers connect to the same server. One problem:version 1.0.1.6 wont let multiple comput- ers with the same CD key connect at the same time, even if on the same LAN (not a problem with 1.0.1.3). As far as hosting games, the HL server does not need to be in the DMZ. Just forward port 27015 or 27016 to the local IP of the server computer. There remains, however, a problem with people being booted after a few minutes with an illegible server message. Can multiple gamers on the LAN get on one game server and play simultaneously with just one public IP address?It depends on which network game or what kind of game server you are using. For example, Unreal Tournament supports multi-login with one public IP. Instant Broadband TMSeries Can I use firmware for other routers with my Wireless AP + Cable/DSL Router?No. If you attempt to use other routers f irmware, you could damage your router. Only use f irmware specif ically written for the Wireless AP + Cable/DSL Router as posted on the Linksys web site: www.linksys.com. What is the maximum number of IP addresses and users supported by the Wireless AP + Cable/DSL Router? The Wireless AP + Cable/DSL Router supports up to 253 IP addresses and users. Where is the Wireless AP + Cable/DSL Router installed on the network? In a typi- cal environment, the Wireless AP + Cable/DSL Router is installed between the Cable/DSL Modem and the LAN. Plug the Wireless AP + Cable/DSL Router into the Cable/DSL Modems Ethernet port. Does the Wireless AP + Cable/DSL Router support IPX or AppleTalk? No. TCP/IP is the only protocol standard for the Internet and has become the global stan- dard for communications. IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk, a commu- nications protocol used on Apple and Macintosh networks, can be used from LAN to LAN connections, but those protocols cannot connect from WAN to LAN. Does the WAN connection of the Wireless AP + Cable/DSL Router support 100Mb Ethernet? Because of the speed limitations of broadband Internet connections, the Wireless AP + Cable/DSL Router’s current hardware design supports 10Mb Ethernet on its WAN port. It does, of course, support 100Mbps over in the auto-sensing Fast Ethernet 10/100 switch on the LAN side of the Wireless AP + Cable/DSL Router. What is Network Address Translationand what is it used for?Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows the Wireless AP + Cable/DSL Router to be used with low cost Internet accounts, such as cable or DSL modems, where only one TCP/IP address is provided by the ISP. The user may have many private addresses behind this single address provided by the ISP.Frequently Asked Questions
What is DMZ?Demilitarized Zone (DMZ) allows one IP Address (computer) to be exposed to the Internet. Some applications require multiple TCP/IP ports to be open.

Check with your browser documentation. 65 Etherfast ®Wireless AP + Cable/DSL Router with PrintServer Instant Broadband TMSeries
To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each node and Wireless AP + Cable/DSL Router, for example, must always acknowledge receipt of each message. Each node must maintain contact with the wireless network even when not actually transmitting data. Achieving these functions simultaneously requires a dynam- ic RF networking technology that links Wireless AP + Cable/DSL Routers and nodes. In such a system, the user’s end node undertakes a search for the best possible access to the system. First, it evaluates such factors as signal strength and quality, as well as the message load currently being carried by each Wireless AP + Cable/DSL Router and the distance of each Wireless AP + Cable/DSL Router to the wired backbone. Based on that information, the node next selects the right Wireless AP + Cable/DSL Router and registers its address. Communications between end node and host computer can then be transmitted up and down the backbone. As the user moves on, the end nodes RF transmitter regularly checks the sys- tem to determine whether it is in touch with the original Wireless AP + Cable/DSL Router or whether it should seek a new one. When a node no longer receives acknowledgment from its original Wireless AP + Cable/DSL Router, it undertakes a new search. Upon f inding a new Wireless AP + Cable/DSL Router, it then re-registers, and the communication process continues. What is BSS ID?A specif ic Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be conf igured with the same BSS ID. What is ESS ID?An Infrastructure conf iguration could also support roaming capability for mobile workers. More than one BSS can be conf igured as an Extended Service Set (ESS). Users within an ESS could roam freely between BSSs while served as a continuous connection to the network wireless stations and Wireless AP + Cable/DSL Routers within an ESS must be conf igured with the same ESS ID and the same radio channel. What is ISM band?The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM (Industrial, Scientif ic and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in the hands of users around the globe. What is Spread Spectrum?Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mis- sion-critical communications systems. It is designed to trade off bandwidth 68 How do I get mIRC to work with the Wireless AP + Cable/DSL Router?Set port for- warding to 113 for the computer on which you are using mIRC. Can I run an application from a remote computer over the wireless network?This will depend on whether or not the application is designed to be used over a net- work. Consult the applications user guide to determine if it supports operation over a network. Can I play computer games with other members of the cordless network?Yes, as long as the game supports multiple players over a LAN (local area network). Refer to the games user guide for more information. What is the IEEE 802.11b standard?The IEEE 802.11b Wireless LAN standards subcommittee, which is formulating a standard for the industry. The objective is to enable wireless LAN hardware from different manufacturers to communi- cate. What IEEE 802.11 features are supported?The Wireless AP + Cable/DSL Router supports the following IEEE 802.11 functions: • CSMA/CA plus Acknowledge protocol • Multi-Channel Roaming • Automatic Rate Selection • RTS/CTS feature • Fragmentation • Power Management What is Ad-hoc?An Ad-hoc wireless LAN is a group of computers, each with a WLAN adapter, connected as an independent wireless LAN. Ad-hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation. What is Infrastructure?An integrated wireless and wired LAN is called an Infrastructure conf iguration. Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers. What is Roaming?Roaming is the ability of a portable computer user to com- municate continuously while moving freely throughout an area greater than that covered by a single Wireless Network Access Point. Before using the roaming function, the PC must make sure that it is the same channel number with the Wireless AP + Cable/DSL Router of dedicated coverage area. 67 Etherfast ®Wireless AP + Cable/DSL Router with PrintServer Instant Broadband TMSeries
AppendixVirtually all Internet addresses are conf igured with words or characters (i.e., www.linksys.com, www.yahoo.com, etc.) In actuality, however, these Internet addresses are assigned to IP addresses, which are the true addresses on the Internet. IP and web addresses, however, can sometimes be long and hard to remember. Because of this, certain ISPs will shorten their server addresses to single words or codes on their users’ web browser or e-mail conf igurations. If your ISP’s E- mail and Web server addresses are conf igured with single words (“www”, “e- mail”, “home”, “pop3”, etc.) rather than whole Internet Addresses or IP Addresses, the Router may have problems sending or receiving mail and accessing the Internet. This happens because the Router has not been conf ig- ured by your ISP to accept their abbreviated server addresses. The solution is to determine the true web addresses behind your ISPs code words. You can determine the IP and web addresses of your ISP’s servers by “pinging” them.Step One: Pinging f or an IP Ad dr ess The f irst step to determining your ISP’s web and e-mail server address is to ping its IP Address. 1. Power on the computer and the cable or DSL modem, and restore the network conf iguration set by your ISP if you have since changed it. 2. Click Start, then Run,and type command. This will bring up the DOS Window. 70 eff iciency for reliability, integrity, and security. In other words, more band- width is consumed than in the case of narrowband transmission, but the trade off produces a signal that is, in effect, louder and thus easier to detect, provid- ed that the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to the right frequency, a spread-spectrum signal looks like background noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS). What is DSSS? What is FHSS? And what are their differences?Frequency-hop- ping spread-spectrum (FHSS) uses a narrowband carrier that changes frequen- cy in a pattern that is known to both transmitter and receiver. Properly syn- chronized, the net effect is to maintain a single logical channel. To an unin- tended receiver, FHSS appears to be short-duration impulse noise. Direct- sequence spread-spectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip (or chipping code). The longer the chip, the greater the probability that the original data can be recov- ered. Even if one or more bits in the chip are damaged during transmission, sta- tistical techniques embedded in the radio can recover the original data without -the need for retransmission. To an unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most narrowband receivers. Would the information be intercepted while transmitting on air?WLAN features two-fold protection in security. On the hardware side, as with Direct Sequence Spread Spectrum technology, it has the inherent security feature of scrambling. On the software side, WLAN series offer the encryption function (WEP) to enhance security and Access Control. Users can set it up depending upon their needs. What is WEP?WEP is Wired Equivalent Privacy; a data privacy mechanism based on a 40 bit shared key algorithm, as described in the IEEE 802.11 stan- dard. 69 Etherfast ®Wireless AP + Cable/DSL Router with PrintServer How to Ping Your ISP’s E-mail & Web Addresses NOTE: If you don’t have your ISP’s web and e- mail IP Addresses, you musteither get them from your ISP or follow these steps priorto connecting the Cable/DSL Router to your network.
