Router FunctionalitiesFirewall
Firewalls are ideal for home networks. They protect computers used privately by the trampling of the destructive efforts of other Web sites and potential hackers. This software or hardware device filter information from the Internet connection, signaling information should not be allowed to be able to. You can see some of these models can be found at: VPN Passthrough
VPN pass-through feature of routers allows traffic between endpoints and do not support one of the endpoints. This feature is supported for the router suitable for home use or small office configurations, they are cheaper than a complete router with VPN endpoints. DHCP server
Dynamic Host Configuration Protocol (DHCP) servers can be implemented for Windows-based system. The server automatically assigns an IP address of the computer's TCP / IP stack software. Wireless Access Point
The performance of the network depends on the signal strength of wireless access points. Before a position to find the exact spot where there is the maximum range of the network. DSL modem
Digital Subscriber Line modems are faster than conventional modems and can use existing phone lines. Both internet and telephone connections for calls can be used simultaneously. Voice over IP Gateway
VoIP routers have both wireless network adapter and telephone handsets. With this function, the network can access both Internet and voice communications. Protocols
These formats to transfer data between devices. The protocols determine the various aspects of data, such as compression molding, delivery and retrieval of equipment and error checking. The standard protocols differ in their different properties, and communicate with other computers correct protocols are selected.
Internet Protocol (IP) enables unique addressing of computers.
Is used in conjunction with the Transport Control Protocol, described it as a TCP / IP.
The new IP version 6, known as IPv6. This version fixes 16 bytes long.
DHCP: Dynamic Host Configuration Protocol assigns dynamic IP addresses to devices on a network. Routing Protocols
The information packets should be routed through a series of routers to reach its goal. Current routers automatically exchange route information with other routers with routing protocols.
Although the configuration of your router, you must choose which type of routing protocol to install and configure.
RIP Version 1: It is a dynamic protocol and routing tables are automatically figures of himself, and manual intervention required. Encryption Standards
With this feature you can configure the virtual private network encryption hardware advanced integration modules and network modules. Data Encryption Standard – applies to 56-bit key block of 64 data bits. This is the most widely used encryption standard. A unique key is used, which is very difficult to break. Triple DES (3DES) – applies 3 keys in succession that it's always difficult to break the code.
Advanced Encryption Standard (AES) will be the next encryption standard for commercial transactions in the private sector. MD5 SHA-1 modulation
There are many standards of modulation. The most common types are: QAM: Quadrature Amplitude Modulation, a dominant modulation technique for high-speed digital signals. CCK: Complimentary Code Keying is a modulation technique to carry data speeds of up to 11 Mbit / s in the HF band. OFDM: Orthogonal Frequency Division Multiplexing modulation for even higher speeds of 54 Mbit / s used. DSSS: Direct Sequence Spread Spectrum use wideband signals that are not easy to recognize and resist the attempts of interference. Security
Today is a home and an office network securely. To counter the efforts of hackers hackers to see well built out in safety features. They will ensure that your system is not slow to see that within the range of your WLAN is not in a position to your files, emails, instant messages, usernames and passwords. After the security features you can also block spam, illegal activities in connection with your Internet connection and prevent loading of dangerous software. This does not mean that your network is absolutely secure. Some measures can be taken include:
Enable WEP, Wired Equivalent Privacy encryption protects the security of wireless networks. WEP key to encrypt the data stream.
Turning on the WPA encryption. The Wi-Fi Protected Access adds the authentication and WEP encryption, as described above.
TKIP, Temporal Key Integrity Protocol covers the weaknesses of WEP encryption.
WPA2 protection is the last and offers a high level of protection.
Enable MAC address filtering Wireless. WEP Encryption Length
WEP is based on a combination of generated user secret key system and values. The index and the exchange of data between access points and clients encrypt being transferred. There are two versions:
The previous version supported 40-bit key length was 40 bits and 24 additional bits of system-generated data, a total of 64 bits.
Easy-Decoding 40-bit WEP encryption, support suppliers to do the encryption to 128 bits. 128-bit encryption, a key length of 104 bits. Antenna Type
The omni-directional antenna of routers broadcast 360 degrees around the router. Place it so that the maximum signal from the membrane.
External antennas can be significantly strength, so that the greater range and increased network performance compared to the performance of integrated antennas.
Removable antennas from 802nd 11a lower band communications as resolved. After attaching the antenna the lower band is enabled. They can be screwed into the device and can be easily improved.
The third type is the integrated internal antennas. These antennas are integrated, and therefore can not be addressed or changed. Brand Name
The wireless routers are still evolving, and at this time that the infant will do well to stay at a brand. Switching between brands can lead to compatibility problems. Linksys and Netgear Wireless are among the few companies which is the largest wireless router ratings a company can receive. Linksys
Linksys wireless routers are easy to install and boast that they give a good performance and signal range. The various features of the router supports protection from hackers with NAT technology, VPN pass-through, and can encrypt all wireless transmissions. Most of its models have excellent performance and support a very useful functions. Some of the features are firewall and routing capabilities, MAC address filtering and virtual server support. Most models are easy to configure, with the browser-based configuration. Netgear
Netgear Wireless Router not only the upper air, but also a good signal strength and wider spectrum. Security features are good and are supported with WPA-PSK, WEP (128 bits). Netgear markets wide range of wireless routers for home networking and business networking. Factors that sales are usability, reliability, quality and safety. Apple
Customers loyal to the brand to wireless routers, the brand, but they are more expensive than the models of other brands to go with similar characteristics. Security features and support are good.
