You can manually connect to a Netgear router by plugging an Ethernet cable into both the router and computer. Once this connection is established, you can type 192.168.1.1  (the default IP address) in the browser in order to access the Netgear router interface. A dialog box should appear asking for the username and password, which is “admin” and “password”, respectively, by default. This type of connection is mostly used to resolve wireless problems or to set up a router for the first time. How To Wirelessly Connect To A Netgear Read More

The FC connector is a fiber optic connector with a threaded body which was designed for use in high-vibration environments. It is widely used with both single-mode and multi-mode fiber. The fiber’s ending point is implanted in a 2.5 mm ferrule (metal cap or band placed on a wooden pole to avoid splitting) made of Zirconium Oxide ceramic or stainless steel. The tip is then furnished to create a rounded surface, called "physical contact". This surface profile means that when the fibers are connected they come in contact only at Read More

An MTRJ connector is a type of fiber optic cable that has an endpoint similar to the RJ-45 connector endpoint found in Ethernet connections. MTRJ connectors are designed to snap into the Ethernet port of a computer, modem, or wireless router and provide that computer or network with extremely fast data transfer rates. MTRJ connectors are usually designed for multi-mode optical fibers but can be used for single mode optical fibers as well. MTRJ connectors are approximately 2.45 mm x 4.4 mm in size and are standardized by the International Read More

An ADSL router is also known as a DSL modem. The router connects the computer to the DSL phone line so the ADSL service can be used. Some countries also use the term NTBBA (Network Termination BroadBand Access). There are some ADSL routers that are also capable of sharing a single Internet connection with a group of computers on a network. This system is also known as the residential gateway. The ATU-R Every ADSL router has a functional block called ADSL Terminal Unit-Remote (ATU-R (transceiver). The ATU-R is responsible for Read More

Bluetooth dial-up networking (DUN) is a wireless Internet technology that refers to connecting to the Internet with a Bluetooth enabled cell phone as a modem. Bluetooth DUN offers a low band alternative where there are no local hotspots to provide high speed wireless Internet access. Bluetooth is a wireless protocol that allows wireless communication to take place in a Personal Area Network (PAN). It uses the frequency hopping spread spectrum to transmit data over short distances from fixed or mobile devices. It is mainly used to exchange information between mobile Read More

A WiFi antenna is a device that sends and or receives radio signals that computers and other electronic devices use to facilitate wireless communication with each other. While WiFi antennas have many uses, they are most commonly found in or on wireless routers. A wireless router is a device that creates a wireless computer network for all computers and devices within its range and requires a WiFi antenna to transfer data between a modem and other devices within the network. WiFi antennas come in many different shapes, sizes, and designs. Read More

In most cases, disabling the firewall on a Netgear router is a really bad idea. In fact, it is such a bad idea that Netgear does not even make a button in their GUI that does this. Nevertheless, users can effectively disable a Netgear router firewall just by adding a rule or two to the firewall configuration. Netgear Router Firewall Default Rules Netgear devices with firewalls have two default rules: Outbound Services: Allow all access from the inside to the outside. Inbound Services: Block all access from the outside to Read More

Switches represent the features and technologies that can be used to respond to the requirements in emerging network design. Some basic operations and technologies of switches are as follows: Fast Convergence: Switches stipulate that the network must adapt quickly to network topology changes. Deterministic Paths: Switches provide desirability of a given path to a destination for certain applications or user groups. Deterministic Failover: Switches specify that a mechanism be in place to ensure that the network is operational all the times. Scalable Size and Throughput: Switches provide the infrastructure that must handle the increased Read More
