Gateway IP: This is the IP address of the host router which resides on the external network and provides the point of connection to the next hop towards the internet. This can be a DSL modem, Cable modem, or a WISP gateway router. The device will direct all the packets to the gateway if the destination host is not within the local network.

Gateway IP address should be from the same address space (on the same network segment) as the device's external network interface (Wireless interface in the Station case and the LAN interface in the AP case).

Primary/Secondary DNS IP: The Domain Name System (DNS) is an internet "phone book" which translates domain names to IP addresses. These fields identify the server IP addresses where the DNS requests are forwarded by the device.

Primary DNS server IP is mandatory. It is used by the DNS Proxy and for the device management purpose.

Secondary DNS server IP address is optional. It is used as the fail-over in case the primary DNS server will become unresponsive.

Enable NAT: Network Address Translation (NAT) enables packets to be sent from the wired network (LAN) to the wireless interface IP address and then sub-routed to other client devices residing on it's local network while the device is operating in AP/AP WDS wireless mode and in the contrariwise direction in "Station/Station WDS" mode.

NAT is implemented using the masquerade type firewall rules. NAT firewall entries are stored in the iptables nat table, while the device is operating in Router mode. Please refer to the iptables tutorial for detailed description of the NAT functionality in Router mode.

Static routes should be specified in order the packets should pass-through the based device if the NAT is disabled in while operating in Router network mode.

Enable DHCP Server: Dynamic Host Configuration Protocol (DHCP) Server assigns IP addresses to clients which will associate to the wireless interface while the device is operating in AP/AP WDS wireless mode and assigns IP addresses to clients which will connect to the LAN interface while the device is operating in Station/Station WDS mode.

Range Start/End: This range determines the IP addresses given out by the DHCP server to client devices on the internal network which use dynamic IP configuration.

Lease Time: The IP addresses given out by the DHCP server will only be valid for the duration specified by the lease time. Increasing the time ensure client operation without interrupt, but could introduce potential conflicts. Lowering the lease time will avoid potential address conflicts, but might cause more slight interruptions to the client while it will acquire new IP addresses from the DHCP server.

DHCP Fallback IP: In case the external network interface of the Router is placed in Dynamic IP Address mode (DHCP) and is unable to obtain an IP address from a valid DHCP server, it will fall back to the static IP address listed here. In case the IP settings of the device are unknown, they can be retrieved with the help of the UConfig utility and should be started on the administrator PC which resides on the same network segment as the device.

802.11N specifications

Compex Systems 802.11N solutions are designed to provide high-performance wireless networking, catering to the growing demand for faster and more reliable connectivity in various applications. The 802.11N standard, also known as Wi-Fi 4, significantly enhances the capabilities of previous Wi-Fi standards by utilizing advanced technologies and features.

One of the key characteristics of Compex Systems 802.11N products is their support for Multiple Input Multiple Output (MIMO) technology. MIMO allows the transmission of multiple data streams simultaneously, effectively improving throughput and range. This is especially useful in environments with high user density or physical obstructions, as it enhances the signal quality and minimizes interference.

Another significant feature is the use of Channel Bonding, which combines two adjacent channels to double the data rate. This capability enables users to experience higher speeds, typically reaching up to 600 Mbps under optimal conditions. The dual-band operation, supporting both 2.4 GHz and 5 GHz frequencies, further enhances flexibility and performance. The 2.4 GHz band offers broader coverage, while the 5 GHz band provides faster speeds with less congestion.

Compex Systems also incorporates advanced security protocols in their 802.11N solutions. With support for WPA2 encryption and robust authentication methods, users can ensure that their connections remain secure, protecting sensitive data from potential threats.

Quality of Service (QoS) is another critical feature, allowing network administrators to prioritize traffic according to application needs. This ensures that bandwidth-intensive applications, such as video streaming and online gaming, receive the necessary resources for optimal performance, even in a crowded network environment.

Designed for versatility, Compex Systems 802.11N devices can be employed in various scenarios, including enterprise, education, healthcare, and hospitality sectors. Their compact and durable designs make them suitable for deployment in both indoor and outdoor settings.

Overall, Compex Systems 802.11N solutions offer a comprehensive set of features and technologies aimed at providing robust, high-speed wireless connectivity. With MIMO, Channel Bonding, dual-band support, enhanced security, and QoS capabilities, these systems are well-suited to meet the demands of modern wireless networking environments.
