The router is also equipped with a built-in 4-port Gigabit Ethernet switch, allowing for wired connectivity with high-speed data transfer rates.

In terms of performance, the 881GW-GN-A-K9 is capable of handling up to 45Mbps of throughput. This means that it can process a large amount of data traffic in a short amount of time, making it suitable for use in high-traffic environments. Additionally, the router supports advanced security features such as VPN and firewall capabilities, which protect the network from unauthorized access and malicious attacks.

In terms of scalability, the 881GW-GN-A-K9 can be upgraded with additional memory and storage as needed to support growing networks. Additionally, the router can be managed and configured through Cisco's web-based interface, which makes it easy to add, remove, or modify network devices as needed. However, the exact scalability will depend on the specific use case and network configuration.

Advanced Security Features

The Cisco 881GW-GN-A-K9 881 Ethernet Wireless Router has several advanced security features built-in to protect the network from unauthorized access and malicious attacks. These features include:

  • Firewall: The router has a built-in firewall that can be configured to block unauthorized access to the network and protect against common network attacks.
  • VPN: The router supports Virtual Private Network (VPN) connections, allowing remote users to securely access the network over the internet.
  • Intrusion Prevention System (IPS): The router includes an Intrusion Prevention System (IPS) that can detect and prevent various types of network attacks, such as denial of service (DoS) and malware.
  • Access Control Lists (ACLs): The router supports the use of Access Control Lists (ACLs) to restrict access to specific network resources based on user or device.
  • Secure Wireless: The router supports wireless security protocols such as WPA2-Enterprise, which encrypts wireless data to protect it from eavesdropping and other wireless attacks.
  • Advanced Malware Protection (AMP) for Endpoints: The router can be integrated with Cisco's Advanced Malware Protection (AMP) for Endpoints to provide real-time monitoring and protection against malware threats.
  • Cisco Identity Services Engine (ISE): The router can be integrated with Cisco Identity Services Engine (ISE) to provide secure network access and policy enforcement based on user identity and device posture.

These features help to protect the network from unauthorized access, malware, and other cyber threats, and can be configured and managed through Cisco's web-based interface to provide optimal security.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Routers lead the line as the first line of network security in homes and offices. It prevents intrusion into a network while creating a firewall to provide the highest level of security on several network types. They are the best ways of keeping computer systems, network systems, and information contained in them safe from intrusion.

A router is designed to be more capable than several other network devices such as hubs or switches that can only carry out basic network functions. For instance, a hub only transfers data between network devices without analyzing or doing anything with those data. On the other hand, routers are able to analyze data sent between network devices. They can change the packaging of such data and send it over to a different network.

Routers are the perfect devices to share an internet connection between multiple computers in home networks. A router typically connects to the modem using a network cable. Router networking occurs via a WAN port or the internet. There are also wireless routers that connect to devices using different wireless standards.

Important Features

Multi-core Processor

The hardware inside these routers allows them to cope with several network use at the same time. Many of these routers come with dual-core and quad-core processors. These processor options allow them to handle lots of data more effectively. Users can use their Wi-Fi routers for activities such as video streaming, online gaming, data backups, and more. Even while carrying out those operations, the routers perform at the highest levels.

Multi-band options

Users will get routers that broadcast wireless signals over two frequencies (for dual-band) or more (for tri-band and others). These routers run at frequencies that can cover a wide expanse of area. They are not congested and are perfect for office buildings, homes, and large enterprises. Clients will find routers that emit their signals between 2.4 GHz and 5GHz.

Built-in Security Features

These router networking devices also come with security features such as device quarantine, firmware updates, automatic updates, and more. The features allow them to provide network-level protection against attacks. With these features, cybercriminals will be unable to infiltrate home networks.

Types of Routers

There are several types of routers that users can benefit from. Some of them include:

  • Core Routers. These are the types used by Internet Service Providers. They are the fastest and most powerful types. They sit at the center of the internet and forward data through the main fiber Optics.
  • Wireless Routers. These work in a similar manner as a home or business LAN. However, they give room for better mobility for laptops, tablets, and other portable devices. These types offer transmission over short distances.
  • Enterprise Routers. These are the types employed by large companies. Organizations use enterprise routers to connect their networks to these core routers.
  • Branch Routers. These types connect an enterprise's remote offices to its Wide Area Network (WAN). They come with improved features such as wireless LAN management, time-division multiplexing, WAN acceleration, and more.
  • Edge Routers. These are the most commonly used types in homes and small businesses. They are low-capacity devices that connect to the public internet or private WAN, or external LAN.
  • Logical Routers. They function similarly to hardware to create several network routes.
