Page 18: Setup
• Firmware Version This entry shows the version and date of the firmware you are using. Future versions of the Gateway’s firmware will be posted and available for download on the Linksys website at www.linksys.com. • Current Time The Gateway will try to reach an Internet timeserver and dis- play the current time in this location. - Page 19 RFC 1483 Bridged This mode supports two additional mode selections in the drop-down menu for the WAN IP Address setting, Dynamic IP Address and Static IP Address. The Setup screen and features displayed will differ depending on which mode you select. Dynamic IP Address Choose this option if your ISP assigns IP addresses via DHCP.
- Page 20 RFC 1483 Routed Choose this option if your ISP told you to use this mode of encapsulation. Use the IP address and DNS Server Address(es) provided by your ISP. Enter the IP address provided by the ISP in the Specify an IP Address field.
- Page 21 RFC 2516 PPPoE Choose this option if your ISP told you to use this mode of encapsulation. Use the User Name, Password, and Service Name (if applicable) provided by your ISP. Figure 6-9 Enter the Service Name (if provided) in the field. Enter the User Name in the Specify an IP Address field.

Page 22: Password
Password On the Password screen, you can change the Gateway’s password, configure SNMP settings, and restore the Gateway’s factory default settings. Figure 6-11 • Router Password It is strongly recommended that you set a password for the Gateway. The default password is admin. If you don’t change the pass- word, all users on your network will be able to access the Gateway using the default password admin. -
Page 23: Status
Status This screen displays the current status of the Gateway; it reflects the data and selections you’ve entered using the Setup screen and provides an option for DHCP users. Note: The information provided and buttons available may vary depending on the Gateway’s settings. All of the information provided on this screen is read-only. - Page 24 DHCP The Gateway can be set up as a DHCP (Dynamic Host Configuration Protocol) server on your network. A DHCP server automatically assigns an IP address to each PC on your network for you. Unless you already have one, it is highly rec- ommended that you leave the Gateway enabled as a DHCP server.

If your situation is described here, the problem should be solved by applying the corresponding solution. If you can’t find an answer here, check the Linksys website at www.linksys.com. 1. The Gateway is not working. • Verify that the Power cord and other network cables are plugged in. -
Page 35: Frequently Asked Questions
ISP. Does the Gateway support any operating system other than Windows 95, Windows 98, Windows 2000, Windows NT, or Windows XP? Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshoot- ing of any non-Windows operating systems. - Page 36 It is best to contact your ISP to find these settings. Will this product work on an SDSL, IDSL or ISDN line? No, those types of lines are not ADSL technologies. The BEFDSR41W will only work on ADSL lines that support the T1.413i2, G.992.1 (G.dmt), or G.992.2 (G.lite) standards.

Page 37: Appendix B: Configuring Wireless Security
WEP encryption has been called 40-bit because it uses a 40-bit secret key along with a 24-bit Initialization Vector (40 + 24 = 64). Wireless vendors may use either name. Linksys uses the term “64-bit” when referring to this level of encryption. - Page 38 • WEP (64Bit or 128B) Select the level of encryption from the drop-down box. 128-bit WEP encryption is unique to Linksys and may conflict with other vendors’ WEP encryption. Note: In order to utilize WEP encryption, all points in your wireless network must have WEP enabled and be set to the same Key Setting.

Page 39: Configuring Wireless Security In Windows Xp
Configuring Wireless Security in Windows XP As Windows XP does not allow for the use of the Linksys Passphrase feature with the wireless PC adapters, you will need to manually enter the key gener- ated in the previous section. The following steps will help you enable WEP and enter the encryption key manually for your wireless PC cards, in order to enable your Windows XP sys- tem to communicate with the Gateway wirelessly. - Page 40 If a “Connect to Wireless Network” window appears, in the Available Networks section, click the desired wireless network, specified by the Gateway’s SSID. Then, double-click the Wireless Network Connection icon. Figure B-7 5. When the “Wireless Network Connection Status” window appears, click the Properties button.
