FunctionalitiesFirewall Router Firewalls are ideal for home networks. They help protect computers use the house by blocking efforts to destroy other official sites and potential hackers. This software or hardware information filters Internet access, which indicates the information should not be allowed to happen. You can find some of these models: VPN Pass through VPN pass through the Router function allows the traffic between the ends and not supporting one end. This is ideal for routers of home use or small office settings, it is less expensive than a full-VPN router that supports the ends. DHCP Dynamic Host Configuration Protocol (DHCP) can be implemented for the Windows-based system. The server automatically assigns an IP address of the software TCP / IP. Wireless Access Point The network performance depends on the signal strength of wireless access point. Before the position, find the exact location where it will be the maximum range of the network. DSL Digital Subscriber Line modems are faster than regular modems and can use the phone lines. Both internet and telephone lines for phone calls can be used simultaneously. Voice over IP VoIP routers have both have wireless networks and adapters for mobile terminal. With this feature of the network can access the Internet and voice communications. Protocols These are the formats for transferring data between different devices. The protocols determine the various aspects of the data like compression types, delivery and recovery of aircraft and error checking. Standard protocols are differentiated by their different characters, so to communicate with other computers correct protocols must be selected. IP (Internet Protocol) is used for the treatment of individual computers. When used with the transport control protocol, known as TCP / IP. The new IP version 6 is known as IPv6. This version addresses 16 bytes in length. DHCP: Dynamic Host Configuration Protocol assigns dynamic IP addresses to devices on a network. Routing Protocols Information packets should be sent through a series of routers to reach its destination. The latest information on the routers automatically exchange route to other routers using routing protocols. Although the configuration of the router on your own, you must choose which type of routing protocol that you have to install and configure. RIP version-1: This is a dynamic protocol and automatically routing tables figures for himself, and manual inputs are not necessary. Encryption This function configures the hardware virtual private network encryption advanced integration modules and network modules. Data Encryption Standard - applies 56-bit key and 64-bit block of data. This is the most widely used encryption standard. A unique key that is used is very difficult to break. Triple DES (3DES) - applies 3 keys in succession making it more difficult to break the code. Advanced Encryption Standard (AES) will be the next encryption standard for commercial transactions in the private sector. MD5 SHA modulation There are many standards of modulation. The most common types are: QAM: Signs of quadrature amplitude modulation, a modulation technique for high speed digital key. CCK: Introduction free code is a modulation scheme to operate at data rates up to 11Mbps in the RF band. OFDM: Orthogonal Frequency Division Multiplexing modulation is used for higher speeds of 54Mbps. DSSS: Direct Sequence Spread Spectrum using broadband signals that are not easy to detect and resist attempts to interfere. Security Today, no home and office network is secure. To counter efforts by pirates piracy, watching the well-integrated security features. This will ensure that the system slows down, those within range of your wireless network are not able to view your files, emails, instant messages, usernames and passwords. According to security features, you can block spam, illegal activities with your Internet connection and prevent loading of dangerous software. This does not mean that your network is secure. Some steps can be taken are: Enable WEP, Wired Equivalent Privacy encryption provides security for wireless networks. WEP keys encrypt the data stream. Turning on WPA encryption. The Wi-Fi Protected adds authentication and WEP encryption features described above. TKIP, Temporal Key Integrity Protocol covers the weaknesses of WEP encryption. WPA2 is the latest protection and provides a high level of protection. Enable wireless MAC address filtering. WEP encryption length WEP is based on a combination of user secret keys generated by the system of values. The figure key and encrypts the data transferred between access points and clients. There are two versions: The previous version supported 40-bit key length was 40 bits and 24 additional bits of system-generated data, for a total of 64 bits. Easy to decode 40-bit WEP encouraged vendors to go for 128-bit encryption. key length of 128-bit to 104 bits. Antenna Type The omnidirectional antenna broadcast routers 360 degrees around the router. Position so that you can get the maximum signal of the membrane. External antennas can add strength significantly, thus providing greater choice and increased network performance compared with the performance of integrated antennas. Disable removable antennas 802. 11a communication lower when they separate. The setting of the lower band antenna is enabled. Thus, you can screw on the device and can be updated easily. The third type is the integrated internal antenna. These antennas are integrated, and therefore can not be changed or controlled. Trade name The wireless routers are still evolving, and this infant stage it will be good to stick to one brand. Switching between brands can lead to compatibility problems. The Linksys and Netgear wireless are among the few companies that have the highest wireless router ratings a company can get. Linksys Linksys wireless routers are easy to install and are reputed to give a good performance and signal range. The different features that the router supports the protection against hackers with NAT, VPN, and can encode all wireless transmissions. Most of its models have excellent performance and support functions very useful. Some features of the firewall and routing capabilities, MAC address filtering and virtual server support. Most models are easy to configure with a browser-based configuration. Netgear Netgear wireless routers seem to have not only greater but also the signal strength is good and greater range. Security features are good and are compatible with WPA-PSK, WEP (128 bits). wide range of markets Netgear wireless routers for home networks and business networks. Listing factors are ease of use, reliability, quality and safety. Apple Customers loyal to the brand can enter the brand wireless routers, which are however more expensive than models from other brands with similar features. Security features and support are good.
