Static IP

If you are required to use a permanent IP address, then select Static IP.

IP Address. This is the IP address that the Router has, when seen from the Internet. Your ISP will provide you with the IP Address you need to specify here.

Subnet Mask. This is the Router’s Subnet Mask, as seen by external users on the Internet (including your ISP). Your ISP will provide you with the Subnet Mask.

Default Gateway. Your ISP will provide you with the Default Gateway Address.

Static DNS 1-3. Your ISP will provide you with at least one DNS (Domain Name System) Server IP Address.

PPPoE

Some DSL-based ISPs use PPPoE (Point-to-Point Protocol over Ethernet) for Internet connections. If you use a DSL line, check with your ISP to see if they use PPPoE. If they do, you will have to enable it.

User Name and Password. Enter the User Name and Password provided by your ISP.

Service Name. Enter the Service Name provided by your ISP.

Connect on Demand and Max Idle Time. You can configure the Router to cut the Internet connection after it has been inactive for a specific period of time (Max Idle Time). If your Internet connection has been terminated due to inactivity, Connect on Demand enables the Router to automatically re-establish your connection as soon as you attempt to access the Internet again. If you wish to activate Connect on Demand, click the radio button. If you want your Internet connection to remain on at all times, enter 0 in the Max Idle Time field. Otherwise, enter the number of minutes you want to have elapsed before your Internet access disconnects.

Keep Alive and Redial Period. This option keeps your Internet access connected indefinitely, even when it sits idle. If you select this option, the Router will periodically check your Internet connection. If the connection is down, then the Router will automatically re-establish the connection. To use this option, click the radio button next to Keep Alive. The default Redial Period is 30 seconds.

When you are finished, click the Save Settings button. Then click the Status tab, and click the Connect button to start the connection.

Note: For DSL users, if you need to enable PPPoE support, remember to remove any PPPoE applications that are installed on your PCs.

BEFSR41 specifications

The Cisco Systems BEFSR41 is a versatile and robust broadband router that has gained popularity for its reliability and feature set, catering to both home users and small businesses. This device integrates an 802.3 Ethernet switch with a wide area network (WAN) port, allowing users to connect multiple local area network (LAN) devices to the internet simultaneously.

One of the standout features of the BEFSR41 is its ability to support up to four Ethernet ports, which facilitates easy connection for computers, printers, and other network devices. This multi-port functionality promotes efficient resource sharing within a network, enabling users to share files, printers, and Internet access seamlessly. The router operates using a robust NAT (Network Address Translation) technology, which enhances network security by ensuring that local IP addresses are not exposed directly to the internet.

The BEFSR41 supports DHCP (Dynamic Host Configuration Protocol), allowing for automatic IP address assignment to connected devices, which simplifies the network setup for users. Furthermore, its built-in firewall features help protect against unauthorized access and potential threats from the internet, making it an ideal choice for small office or home office settings. The router also supports port forwarding, allowing users to configure access for specific applications, such as online gaming or video conferencing.

In terms of connectivity, the BEFSR41 is designed for high-speed broadband connections, making it suitable for DSL or cable internet services. The device offers a straightforward setup process, typically involving a web-based interface that simplifies configuration for users of all technical levels. The compact design and ease of installation make it a convenient choice for those looking to enhance their home or office network.

Additionally, the BEFSR41 supports basic Quality of Service (QoS) features, which enable prioritization of traffic for applications that require higher bandwidth or lower latency. Users can configure these settings to ensure that critical applications receive the necessary resources, promoting a smoother experience during activities like streaming or video calls.

Lastly, the Cisco BEFSR41 is known for its durability and longevity, reflecting the high standards associated with Cisco products. Although newer models and technologies have emerged since its launch, the BEFSR41 remains a solid option for users seeking a reliable and efficient router for basic networking needs.
