Several factors contribute to weak or diminished cable signal strength, such as signal splitting and long cable runs. The farther you live from your cable provider’s substation, the longer the signal must travel, losing strength as distance increases. Splitting the CATV signal also diminishes signal strength. Making a cable TV booster amplifier requires slight modifications to the existing cable line in the interior of the home and a signal repeater with F-connectors. The repeater essentially retransmits the signal without the loss of strength that typically occurs when a signal travels.
The Microsoft TUN Miniport Adapter is a built-in part of Windows networking architectures. This device is designed to handle the tunneling or bridging between network devices. Microsoft developed this miniport to support the new Internet Protocol version 6 (IPv6) technologies. The Microsoft TUN Miniport Adapter is the component that supports TUN devices.
An Ethernet port connects a computer to a network and a USB port connects a computer to peripheral equipment such as a mouse or printer. To change a port from one to the other, you need an electronic adapter often called an Ethernet-to-USB cable. You can't splice the connections together using a pinout diagram.
Connecting to a network is as simple as plugging in a cord or selecting its name from a list on your computer. This simplicity disguises a series of complex mechanisms behind networking technology. Among these mechanisms are the network interfaces that actually connect devices together, and the network-monitoring software that tracks information about the data packet passing through these connections.
Controlling an iPod Touch through the serial port provides a way to send information from your iPod Touch to a larger touchscreen device. The advantages to using a large touchscreen device are that you can more easily use your iPod Touch in the car for music, video and directions. Unless you have a computer or a serial touchscreen device, you won't be able to control your iPod Touch with just a serial port. Additionally, the serial port only allows transfer of audio information; you will need to use Bluetooth or wireless connections to transfer video.
Unshielded twisted-pair, or UTP, and cable television, or CATV, networks transmit data at different rates that depend on an assortment of conditions and situations. UTP networks are capable of transmitting data at up to 100 megabits per second under optimal conditions, while CATV networks can produce speeds of up to 150Mbps, also under ideal conditions.
Computer networks use ports to organize and route traffic sent from one computer to another. Under normal circumstances, a packet, or unit of network data, searches for an available port and, if the port recognizes the data in the packet, it allows the packet to pass through and travel to its destination. However, if the port doesn't recognize the data in the packet, the packet must go to the next available port. Port redirection, or port forwarding, tells a router or firewall to organize packets and direct each group to travel on a specific port, or lane.
Computer network switches are notoriously noisy. Like much electronic equipment, switches radiate a lot of heat and require some sort of cooling system. Because of the cramped size of the case, the cooling fans are tiny and spin fast. A high-RPM fan must work hard to continuously push air out of the switch case, and its motor can be unavoidably loud. If the network switch suddenly starts to whine or chatter then be prepared to replace the switch.
A repeater is a network or communications device that distributes, or propagates, electric signals from one cable to another. By doing so, the repeater amplifies the signal to restore it to full strength. Repeaters are used to counter the decrease in energy, known as attenuation, which occurs when signals travel long distances.
Cisco has built a solid reputation by providing quality networking technology for many years. The Cisco PIX firewall is an inexpensive solution for companies looking for a simple firewall solution. Cisco offers several PIX models with differing configurations priced accordingly. The PIX is suitable for homes, small companies and large corporations that need to secure their networks.
The Institute of Electrical and Electronics Engineers does not provide a complete photovoltaic system certification process for solar inverters, but provides standards for environment safety. Inverters are regulated at state and local levels while standards are set my various domestic and international organizations. Photovoltaic means solar electric. A solar inverter converts DC power generated by solar panels to AC power, which can be off-grid or on-grid, depending on the inverter.
A network interface controller, also called a network interface card or simply a network card, is responsible for connecting a computer to a local area network and transferring data back and forth between the PC and the cable modem or router. Broadcom produces network interface cards, or NICs, that allow computers to connect to a LAN wirelessly. If the Broadcom network card fails to connect to the Internet, basic troubleshooting steps can help users pinpoint and fix problems with the NIC.
The Broadcom BCM5789 is a gigabit Ethernet controller from NetLink that enables users to connect computers in homes and small businesses to local area networks through a wired connection. The controller installs to a PCI Express socket on the motherboard and supports advanced power management features such as wake-on-LAN. If the BCM5789 malfunctions, basic troubleshooting steps include checking hardware and software issues.
SDH stands for Synchronous Digital Hierarchy. SDH is the international standard for sending synchronous data transmissions over a fiber optic cable network that is published by the International Telecommunications Union, or ITU. It is the standardized protocol for multiplexing that is used to exchange data packets between servers and clients on a network. The data packets are combined into a single light signal transmitted by LEDs over a series of channels located on the fiber optic cable network.
Single mode optical cable networks can send enormous amounts of data over a single stream of light. Although the data carried by the optical fiber network can vary significantly, they share the same mode, or phase. Single-mode, or single-phase, fiber optic networks can therefore carry this varied data over a single beam of light with little to no significant degradation. However, like all cables, there is a finite distance over which data can be reliably supplied to the target. The longest single-mode fiber optic networks travel thousands of miles, span multiple continents and serve billions of people in the process.
Fiber optic cable consists of a cylindrical glass thread, or core, surrounded by a jacket made from aramid fiber -- a strong, fire-resistant material -- and a jacket made from polyvinyl chloride (PVC). Fiber optic cable is manufactured in two basic types, known as single mode and multimode, which are both frequently used on local area networks. Single mode and multimode fiber optic cable appear identical externally, but operate differently internally and have different characteristics.
When Roku updated its streaming media player in 2011, the first thing people noticed was its size: just three inches by three inches. Connect the tiny device to your home network and it offers dozens of free and premium channels of movies, TV shows and other content, including "hidden" channels requiring a secret code for access. The top-of-the-line Roku XS also includes a "game remote" with controls enabling you to play games like Angry Birds and Jeopardy. Before you can unlock the world of content, however, you must connect the Roku to your home network. Although the Roku includes an…
Cables made of plastic, copper and gold help keep music blasting, videos playing and printers printing around the world. Stroll into an electronics store and shelves of wires and cables may greet you in the electronics accessories aisle. Because some cables vary significantly in price, you might wind up paying more than you have to. This may occur when a salesperson shows you a more expensive cable and recommends it as a better alternative than the one you’ve chosen. Sometimes you should opt for the costlier brand; other times you should not. Knowing when to turn down higher-priced cables can…
A network switch links several computers or work stations to a common computer network, and provides the stations with access to various services. These services include Internet connectivity supplied by a DSL or cable modem, a cloud server, print capability and related services. Running a USB webcam through the network switch that connects these computers is simple and can serve several purposes. Linkage need not be hardwired; an IP link to the network switch can be run through a WLAN or LAN.
When data has been transferred from a primary location to a secondary location through a USB port, it is called USB offloading. For example, if you want to copy video files from your digital video recorder to a USB flash drive, you can use the USB offload feature to do it.
Gigabit Ethernet is a local area networking technology that delivers units of data, known as packets, at a rate of 1 billion bits, or 1 gigabit, per second. You can see what type of traffic is on gigabit Ethernet network by employing a variety of network traffic monitoring tools, although computer hardware often requires a degree of tuning, so that traffic can be captured and filtered without packets being dropped.
The Ethernet 802.3X full duplex protocol is a subset of the IEEE 802.3 collection of standards that define the physical and data link layers of 10Base5 to 1000BASE5 wired Ethernet. It was defined in 1997, or exactly two years after the introduction of the 100Base-T standard, which is more commonly known as "Fast Ethernet," as it supports data transfer speeds of 100 MB/s.
Figuring out why your Western Digital SATA hard drive cable failed requires some detective work. As Sherlock Holmes pointed out, once you eliminate the impossible, what remains must be the solution to the problem. There are many reasons why the Data Lifeguard diagnostic software from Western Digital might think that your SATA cable has failed, not all of them indicate a faulty cable.
A ring flash is a device that fits around the lens of a DSLR camera to provide even light on a photography subject. It's the preferred flash type for macro photography because it doesn't cause the odd shadows you get from a flash mounted above the camera. Portrait photographers also use ring flashes to provide even light on a subject's face. Making your own fiber optic ring flash is an inexpensive way to experiment with lighting in any photography setting.
Modern flat panel TVs are capable of receiving data directly from the Internet. Whether streaming movies from your network or the Web, or allowing access to "widgets" similar to smartphone apps, CAT5E is a secure and solid connection. Audio/video installations use CAT5E to carry data throughout the house, necessitating an Ethernet jack close to the television.
Ethernet routers play an important part in home and business networks with Internet access. The router ensures that data is properly delivered to the computer, network device or Internet address it is intended for. With networks that have a wireless component, the router often serves as the primary wireless access point as well. Choosing a router requires the comparison of features to determine which router best meets your needs.
When you configure your network with a 2Wire gateway, security is an important feature. Your network offers a single point of entry to gain access to all of your personal information. Understanding the firewall features included with your 2Wire gateway will help you keep your network and your data safe from hackers and malicious attacks. Stateful Packet Inspection is an integrated security feature with the 2Wire firewall.

Choose optical cables for this system based on quality and length needed. Sending an external source such as a satellite or digital cable box into the SC-PT670 theater system via optical brings clear surround sound from your favorite TV shows.
When you are experiencing issues with your NetZero 2Wire modem, you can often check the modem lights to determine what is causing the problem. Once you confirm that there is definitely an Ethernet problem, there are a variety of troubleshooting steps you can perform to resolve your issue. Because Ethernet issues are not ISP (Internet Service Provider) related, there is nothing NetZero can do on the ISP side to resolve the issue.
Cell phone modification software, or "hacks," are unofficial applications that enable you to make changes to your cell phone's read only memory (ROM). You can use hacks to make changes to existing software functions or install an entirely new operating system on your mobile device. Your Samsung's SGH-X480 uses the OptiFlash utility to make changes to your phone's ROM. And if you want to add more functionality to your SGH-X480's serial cable with a hack, use the OptiFlash application to install your modifications onto your phone.
A network hub, alternatively known as an Ethernet hub, provides an inexpensive method to connect the computers on your home. To “hard wire,” or connect, each computer, you must use an Ethernet cable, hence the alternative name. Although you may not be able to send and receive information simultaneously, which makes hubs slower than switches, a Dynex network hub could work if your network includes less than four computers.
A network has many different components and each component must operate properly to ensure the function and security of the entire system. Microsoft and 3M developed the Network Driver Interface Specification to translate the data on your computer so that the network card can understand and execute various commands. NDIS also allows the network card to send data to its destination over a network cable.
Wireless interference from other wireless devices in the area can cause connection problems between a wireless router and a wireless printer.The interference can prevent you from connecting to your printer entirely or cause occasional connection problems. You can sometimes fix this by changing the wireless channel on your router. Wireless routers can operate on multiple channels, some of which may not be subject to interference. Your printer and other wireless devices automatically detect the changed channel.
SATA cables connect hard drives and optical drives to computers. These cables let the drives exchange data with the computer through the motherboard. SATA cables can transmit data faster than the older EIDE ribbon cables, and new hard drives, in particular, need the higher data transmission speed because they are larger and read and write data faster. While SATA drives perform at higher speed, the data they transfer is exactly the same as for the older cables.
With the right combination of really long Ethernet cords and network switches, it is possible to have wired connections to computers spread throughout a house. However, wireless networks make the task of allowing a number of computers that are far apart to connect to the Internet much easier than running cords all over the house.
The WDTV Live player turns your HDTV into a multimedia entertainment center by streaming content from your computer or online directly to your TV's screen. The device is designed to work with the streaming features of the Windows operating system for minimal setup and ease of use. Use the built-in sharing tools in Windows to stream videos and music to the WDTV Live.
If a computer on one IP network -- IP is an abbreviation for Internet Protocol, a code used to label packets of data sent across the Internet -- wishes to communicate with another computer on a different IP network, it must find a route from one network to the other. A default static route is a route that matches all destinations, so a computer can communicate with unknown networks.
Most desktop computers and laptop computers are equipped with a network interface that facilitates connection to a network. These connections can be wired or wireless; most laptops have both types installed. Wired and wireless capacities offer flexible solutions to complement a laptop's portability, but installing multiple network cards in stationary computers offers its own unique benefits.
Category 5 cable is so defined because it meets the specifications to transmit data at 100 megahertz. Typically, Cat 5 cable is found in wired computer network installations. You may need to figure the maximum length of Cat 5 cable that you can run, the radius at which you can bend it or the number of cables that can be run through a conduit tube. All of the specifications for Cat 5 cable make figuring out how and where to use it for a straightforward task.
Chances are good that the computer you use has an RJ45 jack for making network connections. The RJ45 Ethernet connector, in wide use since the 1980s, permits high-speed data access to networks including the Internet. The cable used to connect computers to networks is standard and has an RJ45 plug on each end. For certain kinds of network connections, such as connecting two computers to each other, you need a crossover RJ45 cable in place of the standard cable.
Your Ativa router includes a built-in switch for sharing devices such as a printer, which allows all the computers on your network to send print jobs to one central printer. The router may not automatically detect the connected printer, which prevents the device from appearing in the list of available devices on your computer. The Ativa router may not see the printer if its internal firmware has malfunctioned or you have a program such as a firewall blocking access to the device.
Crimping new ends onto a Cat3 patch cord can resolve connectivity problems that lead to dropped connections and cause premature network equipment failure. Normal wear and tear can cause connectors to come loose over time, and many older cables were originally put together quickly using inadequate tools and procedures. The main cable length of a typical patch cord is durable and rarely fails unless subjected to abnormal conditions, so you can easily make one or more new patch cords from longer cables by crimping on a pair of new ends.
Networking your digital video recorder to your computer grants you access to the content stored on its hard drive. While it is possible to network your DVR to your computers, some cable companies disable this feature to prevent their subscribers from tampering with their network. In the event that you can't network your DVR to your computer, a digital video capture card can be used to save programming from your DVR to your computer.
Category 5 networking cable can be used to create a VGA cable suitable for use with typical monitors that use standard 15-pin video connectors. Because Cat 5 patch cords only contain eight conductors, they must be used in pairs to obtain the necessary 15 conductors required for a VGA signal. The standard engineering limit of 15 feet is the maximum length allowed for a VGA cable without using specialized range extenders for longer distances.
Cable trays prevent a mass of cables and wires from hanging down into a room or under a desk. They make the area tidier and, therefore, safer to move around in by keeping the cables secured in one place. You can make a cable tray for a desk that does not already have one and increase the usable space underneath your work space.
Dazzle family and friends by adding fiber optics to countertops, tabletops and even floors -- quite the nighttime light show. Acrylic fibers reflect light from one end to the other until it finally exits the far end. Insert illuminated strands of flexible and extremely thin fiber optic cable into the patterned surface form before pouring concrete. The fiber-optics pattern and colors are all up to you.
