    Are you satisfied with how your home network works today? Even if the answer is 'yes,' the time for upgrading it will eventually come, probably sooner than you think. Network technology improves with each generation of technology, making older products obsolete, so the benefits of upgrading can be significant. Consider these reasons why you may need to start planning for a home network upgrade. 1 Improve the Reliability of a Home Network Home broadband routers are prone to malfunction due to their central role on the network. Common causes of home router failures include overheating, firmware bugs, and other technical glitches that a homeowner cannot easily fix themselves. It can be much cheaper in the long run to buy a new router than to spend hours troubleshooting these failures or dealing with the inconvenience of having to reset the device periodically. 2 Add Wireless Capability to Home Networks Earlier generations of home routers

    While most home computer networks only use one router, adding a second router makes sense in a few situations: Upgrading a wired network to also support wireless devices Extending the wireless range of a home network to reach dead spots Networking a wired device that's too far away from the original router Creating a separate subnetwork within the home to stream video among some devices without bogging down connections to others Making it all work requires just a few steps. Positioning a Second Router When setting up a new router, place it near a Windows PC or other computer that can be used for the initial configuration. Both wired and wireless routers are best configured from a computer connected via Ethernet network cable. The router can be moved to its permanent location later. Connecting a Second Wired Router A second (new) router that doesn't have wireless capability must be connected

    The Advanced Startup Options menu, available in Windows 10 and Windows 8, is the central fix-it location for the entire operating system. From here you can access Windows diagnostic and repair tools like Reset This PC, System Restore, Command Prompt, Startup Repair, and much more. Advanced Startup Options is also where you access Startup Settings, the menu that includes Safe Mode, among other startup methods that could help you access Windows 10 or Windows 8 if it is having problems starting. The Advanced Startup Options menu should appear automatically after two consecutive startup errors. However, if you need to open it manually, there are six different ways to do so. The best way to decide which method to use to open Advanced Startup Options is to base your decision on what level of access you have to Windows right now: If Windows 10/8 starts normally: Use any method, but 1, 2,

    Question: What is the Range of a Typical WiFi Network? Answer: The range of a WiFi computer network depends primarily on the number and type of wireless access points (including wireless routers) used to build it. A traditional home network having one wireless router can cover a single-family dwelling but often not much more. Business networks with grids of access points can cover large office buildings. And wireless hotspots spanning several square miles (kilometers) have been built in some cities. The cost to build and maintain these networks increases significantly as the range increases, of course. The WiFi signal range of any given access point also varies significantly from device to devices. Factors that determine the range of one access point include: the specific 802.11 protocol it runs the strength of its device transmitter the nature of physical obstructions and/or radio interference in the surrounding area A general rule of

    In wireless networking, dual band equipment is capable of transmitting in either of two different standard frequency ranges.  Modern Wi-Fi home networks feature dual band broadband routers that support both 2.4 GHz and 5 GHz channels. The History of Dual Band Wireless Routers First generation home network routers produced during the late 1990s and early 2000s contained a single 802.11b Wi-Fi radio operating on the 2.4 GHz band. At the same time, a significant number of business networks supported 802.11a (5 GHz) devices. The first dual band Wi-Fi routers were built to support mixed networks having both 802.11a and 802.11b clients. Starting with 802.11n, Wi-Fi standards began including simultaneous dual band 2.4 GHz and 5 GHz support as a standard feature. Two Examples of Dual Band Wireless Routers The TP-LINK Archer C7 AC1750 Dual Band Wireless AC Gigabit Router (buy on Amazon.com) has 450Mbps at 2.4GHz and 1300Mbps at 5GHz, as well as IP-based bandwidth control so you can monitor the bandwidth of all the devices connected to your

    Private Branch Exchange Explained A PBX (Private Branch Exchange) is a system that allows an organization to manage incoming and outgoing phone calls and also allows communication internally within the organization. A PBX is made up of both hardware and software and connects to communication devices like telephone adapters, hubs, switches, routers and of course, telephone sets. The most recent PBXs have a wealth of very interesting features that make communication easy and more powerful within for organizations, and contributes in making them more efficient and in boosting productivity. Their sizes and complexity vary, ranging from very expensive and complex corporate communication systems to basic plans that are hosted on the cloud for a two-digit monthly fee. You can also have simple PBX systems at home with basic features as an upgrade to your existing traditional phone line. What Does a PBX Do?  As mentioned above, the functions of a

    Keeping track of passwords can seem like a hassle. Most of us have multiple sites we visit which require password logins. So many, in fact, that it's tempting to use the same username/password combo for all of them. Don't. Otherwise, it takes only the compromise of a single site's credentials to have a toppling domino affect on the security of all your online assets. Fortunately, there is a fairly straightforward way to have different passwords for each site you use but still make the passwords easy enough to remember. Creating Unique Passwords Before you begin creating strong passwords, you need to consider the use of those passwords. The intent is to create strong passwords unique to each account, but easy enough to memorize. To do this, first begin by splitting the sites you frequently login to into categories. For example, your category list might read as follows: social networking sites

    Building the local area network that's right for you Computer networks for the home and small business can be built using either wired or wireless technology. Wired Ethernet has been the traditional choice in homes, but Wi-Fi and other wireless options are gaining ground fast. Both wired and wireless can claim advantages over each other; both represent viable options for home and other local area networks (LANs). Below we compare wired and wireless networking in five key areas: ease of installation total cost reliability performance security About Wired LANs Wired LANs use Ethernet cables and network adapters. Although two computers can be directly wired to each other using an Ethernet crossover cable, wired LANs generally also require central devices like hubs, switches, or routers to accommodate more computers. For dial-up connections to the Internet, the computer hosting the modem must run Internet Connection Sharing or similar software to share the connection with

    Most computers on TCP/IP networks that need name resolution support use the Domain Name System (DNS). Setting up DNS on client devices requires identifying the DNS servers to use. Network administrators (on the Internet, service providers) install and maintain these DNS servers. Numerous providers have set up DNS servers on the Internet for free public access including the especially popular and well-known ones listed below. To utilize any of these services, specify the IP addresses of their primary and secondary DNS servers in a device's or network's TCP/IP configuration. Some providers also offer other optional services, such as site filtering, in addition to standard name resolution. Public Internet DNS Servers A good DNS server supports both high performance and reliability. Especially on high-traffic networks, DNS servers must handle a significant load of name and address look-ups to support Web browsing, email and other usages. DNS reliability can vary depending on

    If you want to completely erase a hard drive, it's not as easy as deleting everything on it. To truly erase hard drive data forever, you'll have to take some extra steps. When you format a hard drive you don't actually erase the hard drive of data, you only erase the location information for the data, making it "lost" to the operating system. Since the operating system can't see the data, the drive looks empty when you look at its contents. However, all the data is still there and, unless you truly erase the hard drive, can be recovered using special software or hardware. The most responsible thing you can do before recycling a hard drive, or even disposing of one, is to completely erase the hard drive. If you don't erase the hard drive, you risk exposing sensitive personal data that you previously deleted - data like social security

    There has never been a better time to cut the cord. Just a few years ago, dropping cable meant going without some of the shows you may have wanted to watch. But these days, it's easy to cancel your cable subscription, watch all of your favorite shows, and still save some money off your monthly bill. Perhaps the worst aspect of cable is the multiyear contract you have to sign to bring the price down from astronomical to still-too-high-for-what-I-get. It's just the opposite when you cut the cord. Most of the services you will use as a replacement for cable television have month-to-month subscriptions, which means you can cancel it for a month if you don't think you will need it. If multiyear contracts are the worst, renting hardware is a close second. Many services charge $15-$25 a month for a DVR receiver and $5-$10 a month to connect additional

    You need to format a hard drive if you plan on using it in Windows or Mac, or Linux... To format a hard drive means to delete any information on the drive and to set up a file system so your operating system can read data from, and write data to, the drive. As complicated as that might sound, it's not really difficult to format a hard drive in any version of Windows. This ability is a very basic function that all operating systems have and Windows makes it pretty easy. Important: If the hard drive you want to format has never been used, or was just wiped clean, it must first be partitioned. See How To Partition a Hard Drive in Windows for instructions. Once partitioned, return to this page for help formatting the drive. Time Required: The time it takes to format a hard drive in Windows depends
