MAC Filter

If you want to restrict users from accessing certain Internet applications / services (e.g. Internet websites, email, FTP etc.), and then this is the place to set that configuration. Access Control allows users to define the traffic type permitted in your LAN. You can control which PC client can have access to these services.

Enable MAC Filtering: Check to enable or disable MAC Filtering.

Deny: If you select “Deny” then all clients will be allowed to access Internet except for the clients in the list below.

Allow: If you select “Allow” then all clients will be denied to access Internet except for the PCs in the list below.

Add PC MAC Address

Fill in “LAN MAC Address” and <Description> of the PC that is allowed to access the Internet, and then click <Add>. If you find any typo before adding it and want to retype again, just click <Reset> and the fields will be cleared.

Remove PC MAC Address

If you want to remove some PC from the “MAC Filtering Table”, select the PC you want to remove in the table and then click <Delete Selected>. If you want to remove all PCs from the table, just click the <Delete All> button. If you want to clear the selection and re-select again, just click <Reset>.

Click <Apply> at the bottom of the screen to save the above configurations.

802.11 specifications

NetComm 802.11 refers to the standards established under the IEEE 802.11 family, which governs wireless networking technologies. This set of protocols enables wireless communication between devices, including computers, smartphones, and IoT devices, providing the foundation for Wi-Fi technology. Understanding the main features, technologies, and characteristics of NetComm 802.11 is essential for leveraging its potential in modern networking.

One of the primary features of NetComm 802.11 is its ability to support various frequency bands, primarily operating in the 2.4 GHz and 5 GHz bands. The 2.4 GHz band offers extensive coverage and is ideal for penetrating walls and obstacles, catering to a more extensive range of devices. In contrast, the 5 GHz band provides faster data rates and less interference from other household devices, making it suitable for high-bandwidth applications like video streaming and online gaming.

Technically, the 802.11 standard has evolved through multiple amendments, with notable versions including 802.11n, 802.11ac, and 802.11ax (Wi-Fi 6). 802.11n introduced Multiple Input Multiple Output (MIMO) technology, which utilizes multiple antennas for transmitting and receiving data, significantly enhancing throughput and coverage. 802.11ac further increased data rates with wider channels and advanced modulation techniques, achieving speeds up to 1 Gbps or more. The latest 802.11ax, or Wi-Fi 6, optimizes performance in congested environments through technologies like Orthogonal Frequency Division Multiple Access (OFDMA) and improved MIMO capabilities.

Another characteristic of NetComm 802.11 is its implementation of security protocols. The standard provides several encryption methods, including WEP, WPA, and WPA2, which have evolved to provide more robust security against unauthorized access. WPA3 is the latest standard that enhances protection against brute-force attacks and improves user experience with simplified device onboarding.

In addition to security, NetComm 802.11 supports Quality of Service (QoS) protocols, which prioritize bandwidth for critical applications, ensuring smoother performance for voice and video communications. The introduction of mesh networking capabilities has further revolutionized how Wi-Fi networks can be deployed, allowing for seamless coverage across large areas without dead spots.

In summary, NetComm 802.11 underpins the essential functionalities of wireless networking. Its versatility in frequency bands, progressive technological advancements, strong focus on security, and support for QoS make it a vital standard for modern connectivity, catering to the increasing demands for speed, reliability, and security in a degital world.
