How To Map a Network Drive in Windows XP Using Windows ExplorerBy Bradley Mitchell, About.com Guide

See More About:pc to pc file transfermicrosoft windows explorerWindows XP supports several different methods for mapping a network drive. A network drive is a file folder located on a remote computer that has been configured for sharing over a LAN. These instructions explain the process to map a shared network drive using Windows Explorer.Difficulty: EasyTime Required: 1 minuteHere's How:Open Windows Explorer or My Computer from the Windows Start Menu.

From the Tools menu, click Map Network Drive…. A new Map Network Drive window opens.

In the Map Network Drive window, choose an available drive letter from the dropdown list located next to the "Drive:" option. Any drives already mapped will have a shared folder name displayed inside the dropdown list, next to the drive letter.

Type the name of the folder to map. This name must follow UNC. Alternatively, click the Browse… button to find the correct folder by browsing available network shares.

Click the "Reconnect at login" checkbox if this network drive should be mapped permanently. Otherwise, this drive will un-map when the user logs out of this computer.

If the remote computer that contains the shared folder requires a different username and password to log in, click the "different user name" hyperlink to enter this information.

Click Finish.

If the drive letter was previously mapped to a different location, a message box will appear asking to replace the current connection with the new one. Click Yes to disconnect and un-map the old mapped drive.

If the Finish operation succeeds, the network drive will be mapped. If the network drive cannot be mapped, ensure the folder name is spelled correctly, that this folder was correctly set up for sharing on the remote computer, that (if necessary) the correct username and password have been entered, and that the computer network connections are functioning properly.Tips:To disconnect a mapped network drive, use the Tools/Disconnect Network Drive… option in Windows Explorer, or right-click on the folder in My Computer and choose the "Disconnect" menu option.What You NeedA local computer running Microsoft Windows XPThe UNC name of a shared folder on a remote computerWorking LAN connections on both the local and remote computersSuggested ReadingHow to Find Shared Windows Folders in Windows XPHow to Enable or Disable Simple File Sharing in Windows XPHow to Find IP and MAC AddressesSuggested ReadingHow to Release and Renew IP AddressesFind Temporary Internet Files in Internet ExplorerRelated ArticlesFile Sharing OS X 10.5 to Windows XP - Mapping Network SharesFile Sharing OS X 10.5 to Windows Vista - Mapping Network SharesProgrammatically Execute the Map Network Drive Dialog to Map a UNC Path to ...Disconnect a Network Drive from Delphi - Programmatically Remove a Network ...How to Encrypt Files Using TrueCrypt

How To Enable and Disable Network Connections in WindowsBy Bradley Mitchell, About.com Guide

See More About:microsoft windows internet connectionstroubleshooting home networksMicrosoft Windows allows you to enable and disable installed network connections. When a network connection suddenly stops functioning, disabling and re-enabling it can repair the problem. Additionally, many Windows computers have multiple network connections installed. Sometimes these connections may interfere with each other. Disabling individual connections when they are not being used can improve network reliability and security.Difficulty: EasyTime Required: < 1 minuteHere's How:Open the Windows Control Panel. Control Panel can be found on the Windows Start Menu.

Click the "Network and Internet" or "Network Connections" option in Control Panel. (If necessary, first open the "Network and Internet Connections" icon in Control panel, then choose "Network Connections" from within that screen.) The Control Panel will refresh to show new options.

In Windows 7 or Windows Vista, click the "View network status and tasks" option from the Network and Internet window to open the Network and Sharing Center.

In Windows XP, the Network Connections window lists all Dial-up and LAN / High-Speed Internet connections installed. In the list of LAN / High Speed Internet connections, select the icon that corresponds to the network you wish to enable or disable.

In Windows 7 or Windows Vista, click the "Connect or disconnect" option shown to pop up a window displaying the current connection status. Use this window to first Disconnect from the active network and then immediately reconnect.In Windows XP, right-click on the selected network connection. A pop-up menu appears. If the connection is currently enabled, the first option in this menu will be "Disable." Otherwise, the first menu option will be "Enable." Select this first menu option to alternately disable or enable the connection.

10 Tips for Wireless Home Network SecurityBy Bradley Mitchell, About.com Guide

See More About:wi-fi network securityhome network securityhome security systems

Many folks setting up wireless home networks rush through the job to get their Internet connectivity working as quickly as possible. That's totally understandable. It's also quite risky as numerous security problems can result. Today's Wi-Fi networking products don't always help the situation as configuring their security features can be time-consuming and non-intuitive. The recommendations below summarize the steps you should take to improve the security of your home wireless network.

1. Change Default Administrator Passwords (and Usernames)At the core of most Wi-Fi home networks is an access point or router. To set up these pieces of equipment, manufacturers provide Web pages that allow owners to enter their network address and account information. These Web tools are protected with a login screen (username and password) so that only the rightful owner can do this. However, for any given piece of equipment, the logins provided are simple and very well-known to hackers on the Internet. Change these settings immediately.More Info2. Turn on (Compatible) WPA / WEP EncryptionAll Wi-Fi equipment supports some form of encryption. Encryption technology scrambles messages sent over wireless networks so that they cannot be easily read by humans. Several encryption technologies exist for Wi-Fi today. Naturally you will want to pick the strongest form of encryption that works with your wireless network. However, the way these technologies work, all Wi-Fi devices on your network must share the identical encryption settings. Therefore you may need to find a "lowest common demoninator" setting.More Info3. Change the Default SSIDAccess points and routers all use a network name called the SSID. Manufacturers normally ship their products with the same SSID set. For example, the SSID for Linksys devices is normally "linksys." True, knowing the SSID does not by itself allow your neighbors to break into your network, but it is a start. More importantly, when someone finds a default SSID, they see it is a poorly configured network and are much more likely to attack it. Change the default SSID immediately when configuring wireless security on your network.More Info4. Enable MAC Address FilteringEach piece of Wi-Fi gear possesses a unique identifier called the physical address or MAC address. Access points and routers keep track of the MAC addresses of all devices that connect to them. Many such products offer the owner an option to key in the MAC addresses of their home equipment, that restricts the network to only allow connections from those devices. Do this, but also know that the feature is not so powerful as it may seem. Hackers and their software programs can fake MAC addresses easily.More Info5. Disable SSID BroadcastIn Wi-Fi networking, the wireless access point or router typically broadcasts the network name (SSID) over the air at regular intervals. This feature was designed for businesses and mobile hotspots where Wi-Fi clients may roam in and out of range. In the home, this roaming feature is unnecessary, and it increases the likelihood someone will try to log in to your home network. Fortunately, most Wi-Fi access points allow the SSID broadcast feature to be disabled by the network administrator.More Info6. Do Not Auto-Connect to Open Wi-Fi NetworksConnecting to an open Wi-Fi network such as a free wireless hotspot or your neighbor's router exposes your computer to security risks. Although not normally enabled, most computers have a setting available allowing these connections to happen automatically without notifying you (the user). This setting should not be enabled except in temporary situations.More Info7. Assign Static IP Addresses to DevicesMost home networkers gravitate toward using dynamic IP addresses. DHCP technology is indeed easy to set up. Unfortunately, this convenience also works to the advantage of network attackers, who can easily obtain valid IP addresses from your network's DHCP pool. Turn off DHCP on the router or access point, set a fixed IP address range instead, then configure each connected device to match. Use a private IP address range (like 10.0.0.x) to prevent computers from being directly reached from the Internet.More Info8. Enable Firewalls On Each Computer and the RouterModern network routers contain built-in firewall capability, but the option also exists to disable them. Ensure that your router's firewall is turned on. For extra protection, consider installing and running personal firewall software on each computer connected to the router.More Info9. Position the Router or Access Point SafelyWi-Fi signals normally reach to the exterior of a home. A small amount of signal leakage outdoors is not a problem, but the further this signal reaches, the easier it is for others to detect and exploit. Wi-Fi signals often reach through neighboring homes and into streets, for example. When installing a wireless home network, the position of the access point or router determines its reach. Try to position these devices near the center of the home rather than near windows to minimize leakage.More Info10. Turn Off the Network During Extended Periods of Non-UseThe ultimate in wireless security measures, shutting down your network will most certainly prevent outside hackers from breaking in! While impractical to turn off and on the devices frequently, at least consider doing so during travel or extended periods offline. Computer disk drives have been known to suffer from power cycle wear-and-tear, but this is a secondary concern for broadband modems and routers.

If you own a wireless router but are only using it wired (Ethernet) connections, you can also sometimes turn off Wi-Fi on a broadband router without powering down the entire network.More InfoReaders Respond: Hacks and Horror Stories in Wireless Network SecurityRead responses (11) Have You Been a Victim?Suggested ReadingAre Wireless Networks Secure?What Is a Passphrase?What Is the Signal Range of a Wi-Fi LAN?Wireless Security - Related TopicsTips for Maintaining a Wireless Home NetworkAbout Wireless RoutersTop Wi-Fi Hotspot FindersRelated ArticlesHoliday Gift Guide for Wireless and Home Computer NetworkingHow to Build a Wireless Home Network - Installing and Configuring EquipmentBuild a Home Network - Wireless RoutersWireless Home Networking Books - Wi-Fi Home NetworksLost Network Connection - Dropped Wi-Fi Network Connections

Network Topologies

network diagramsIn computer networking, topology refers to the layout of connected devices. This article introduces the standard topologies of networking.Topology in Network DesignThink of a topology as a network's virtual shape or structure. This shape does not necessarily correspond to the actual physical layout of the devices on the network. For example, the computers on a home LAN may be arranged in a circle in a family room, but it would be highly unlikely to find a ring topology there.

are categorized into the following basic types: bus ring star tree meshMore complex networks can be built as hybrids of two or more of the above basic topologies. Bus TopologyBus networks (not to be confused with the system bus of a computer) use a common backbone to connect all devices. A single cable, the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see, but only the intended recipient actually accepts and processes the message.

Ethernet bus topologies are relatively easy to install and don't require much cabling compared to the alternatives. 10Base-2 ("ThinNet") and 10Base-5 ("ThickNet") both were popular Ethernet cabling options many years ago for bus topologies. However, bus networks work best with a limited number of devices. If more than a few dozen computers are added to a network bus, performance problems will likely result. In addition, if the backbone cable fails, the entire network effectively becomes unusable.

Illustration - Bus Topology DiagramRing TopologyIn a ring network, every device has exactly two neighbors for communication purposes. All messages travel through a ring in the same direction (either "clockwise" or "counterclockwise"). A failure in any cable or device breaks the loop and can take down the entire network.

To implement a ring network, one typically uses FDDI, SONET, or Token Ring technology. Ring topologies are found in some office buildings or school campuses.

Illustration - Ring Topology DiagramStar TopologyMany home networks use the star topology. A star network features a central connection point called a "hub node" that may be a network hub, switch or router. Devices typically connect to the hub with Unshielded Twisted Pair (UTP) Ethernet.

Compared to the bus topology, a star network generally requires more cable, but a failure in any star network cable will only take down one computer's network access and not the entire LAN. (If the hub fails, however, the entire network also fails.)

Illustration - Star Topology DiagramTree TopologyTree topologies integrate multiple star topologies together onto a bus. In its simplest form, only hub devices connect directly to the tree bus, and each hub functions as the root of a tree of devices. This bus/star hybrid approach supports future expandability of the network much better than a bus (limited in the number of devices due to the broadcast traffic it generates) or a star (limited by the number of hub connection points) alone.

Illustration - Tree Topology DiagramMesh TopologyMesh topologies involve the concept of routes. Unlike each of the previous topologies, messages sent on a mesh network can take any of several possible paths from source to destination. (Recall that even in a ring, although two cable paths exist, messages can only travel in one direction.) Some WANs, most notably the Internet, employ mesh routing.

A mesh network in which every device connects to every other is called a full mesh. As shown in the illustration below, partial mesh networks also exist in which some devices connect only indirectly to others.

Illustration - Mesh Topology DiagramSummaryTopologies remain an important part of network design theory. You can probably build a home or small business computer network without understanding the difference between a bus design and a star design, but becoming familiar with the standard topologies gives you a better understanding of important networking concepts like hubs, broadcasts, and routes.

Can Two Routers Be Used on the Same Home Network?By Bradley Mitchell, About.com Guide

See More About:home network setupbroadband router configurationQuestion: Can Two Routers Be Used on the Same Home Network?You or your family may be considering purchasing a new home network router to upgrade from an older one. Or perhaps you have a very large home network already and are wondering whether a second router can improve performance.Answer: It is technically possible to utilize two routers on the same home network. The benefits of a two router network include: supports more devices - if your first router is a wired Ethernet router, it supports only a limited number of connected devices (typically only four or five). A second router provides more open ports allowing additional computers to join the network.

can simply hybrid network setups - if you have a wired home network and want to connect some new Wi-Fi devices to it, installing a wireless router as the second router allows those devices to connect while allowing the rest of the network to remain on Ethernet.

wireless range / reach - adding a second wireless router to a Wi-Fi network can extend the reach of your network to accommodate far away devices.

network isolation - If you heavily utilize the network connection between certain computers (such as frequent large file transfers, or LAN gaming), installing those computers to use one router, isolates the network traffic from affecting the other router and all of its attached devices.Installing a Two Router NetworkInstalling a router to work as the second one on a home network requires special configuration. Setup involves choosing a good location, ensuring the right physical connections, and configuring IP address settings (including DHCP).

→ More - How to Connect Two Routers on a Home NetworkAlternatives To a Second RouterInstead of adding a second wired router to an existing network, consider adding an Ethernet switch instead. A switch accomplishes the same goal of extending the size of a network, but it does not require any IP address or DHCP configuration, greatly simplifying setup.Readers Respond: Do you want to use two routers on your home network?Read responses (64) Share Your ReasonSuggested ReadingDo Wireless Routers Support Hybrid Networks?What Hardware Is Required to Build a Wireless Network?What Is the Typical Range of a Wi-Fi Network?More About Network RoutersBefore You Buy A Home Network RouterHome Networking With a RouterWhat Is the Difference Between a Router and a Hub or Switch?Related ArticlesDo You Use Two Routers on Your Home Network?Router - What is a Router? - Residential GatewayWireless Product Equipment - Network Routers Access Points Adapters192.168.1.101 - Private IP AddressHow To Identify Network Hardware IP Addresses on a Local Network

Introduction to Network TypesLAN, WAN and Other Area NetworksBy Bradley Mitchell, About.com Guide

See More About:types of area networkslocal area networkswide area networksOne way to categorize the different types of computer network designs is by their scope or scale. For historical reasons, the networking industry refers to nearly every type of design as some kind of area network. Common examples of area network types are: LAN - Local Area Network WLAN - Wireless Local Area Network WAN - Wide Area Network MAN - Metropolitan Area Network SAN - Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network CAN - Campus Area Network, Controller Area Network, or sometimes Cluster Area Network PAN - Personal Area Network DAN - Desk Area NetworkLAN and WAN were the original categories of area networks, while the others have gradually emerged over many years of technology evolution.

Note that these network types are a separate concept from network topologies such as bus, ring and star.See also - Introduction to Network TopologiesLAN - Local Area NetworkA LAN connects network devices over a relatively short distance. A networked office building, school, or home usually contains a single LAN, though sometimes one building will contain a few small LANs (perhaps one per room), and occasionally a LAN will span a group of nearby buildings. In TCP/IP networking, a LAN is often but not always implemented as a single IP subnet.

In addition to operating in a limited space, LANs are also typically owned, controlled, and managed by a single person or organization. They also tend to use certain connectivity technologies, primarily Ethernet and Token Ring.WAN - Wide Area NetworkAs the term implies, a WAN spans a large physical distance. The Internet is the largest WAN, spanning the Earth.

A WAN is a geographically-dispersed collection of LANs. A network device called a router connects LANs to a WAN. In IP networking, the router maintains both a LAN address and a WAN address.

A WAN differs from a LAN in several important ways. Most WANs (like the Internet) are not owned by any one organization but rather exist under collective or distributed ownership and management. WANs tend to use technology like ATM, Frame Relay and X.25 for connectivity over the longer distances.LAN, WAN and Home NetworkingResidences typically employ one LAN and connect to the Internet WAN via an Internet Service Provider (ISP) using a broadband modem. The ISP provides a WAN IP address to the modem, and all of the computers on the home network use LAN (so-called private) IP addresses. All computers on the home LAN can communicate directly with each other but must go through a central gateway, typically a broadband router, to reach the ISP.Other Types of Area NetworksWhile LAN and WAN are by far the most popular network types mentioned, you may also commonly see references to these others: Wireless Local Area Network - a LAN based on WiFi wireless network technology Metropolitan Area Network - a network spanning a physical area larger than a LAN but smaller than a WAN, such as a city. A MAN is typically owned an operated by a single entity such as a government body or large corporation. Campus Area Network - a network spanning multiple LANs but smaller than a MAN, such as on a university or local business campus. Storage Area Network - connects servers to data storage devices through a technology like Fibre Channel. System Area Network - links high-performance computers with high-speed connections in a cluster configuration. Also known as Cluster Area Network.Readers Respond: How Big (or Small) is Your Computer Network?Read responses (67) Tell Us About Your SetupNetwork Types - Related ResourcesWhat Is Computer Networking?VPN - Virtual Private NetworkHow to Find a Router's IP AddressRelated ArticlesWAN - Wide Area Networks in Computer NetworkingVisual Networking Overview - Wide Area NetworksLAN - Local Area Network (LAN)What is a WAN?Networking Fundamentals - Computer and Wireless Networking Basics

How Can the Range of a Wi-Fi Network Be Boosted?By Bradley Mitchell, About.com Guide

See More About:expanding a wireless networkwireless access pointsnetwork repeaterswireless antennaswireless signal interferenceQuestion: How Can the Range of a Wi-Fi Network Be Boosted?You can boost the signal range of a Wi-Fi computer network in several ways:Answer: reposition your router (or access point) to avoid obstructions and radio interference. Both reduce the range of Wi-Fi network equipment. Common sources of interference in residences include brick or plaster walls, microwave ovens, and cordless phones. Additionally, consider changing the Wi-Fi channel number on your equipment to avoid interference.

upgrade the antenna on your router (or access point). Wi-Fi antennas on most wireless base stations can be removed and replaced with more powerful ones.

add another access point (or router). Large residences typically require no more than two APs, whereas businesses may employ dozens of APs. In a home, this option requires connecting your primary wireless router (access point) to the second one with Ethernet cable; home wireless routers and/or APs don't normally communicate with each other directly.

add a bi-directional Wi-Fi signal amplifier to wireless devices as needed. A Wi-Fi signal amplifier (sometimes called "signal booster") attaches to a router, access point or Wi-Fi client at the place where the antenna connects. Bi-directional antennas amplify the wireless signal in both transmit and receive directions. These should be used as Wi-Fi transmissions are two-way radio communications.

add a Wi-Fi repeater. A wireless repeater is a stand-alone unit positioned within range of a wireless router (access point). Repeaters (sometimes called "range expanders") serve as a two-way relay station for Wi-Fi signals. Clients too far away from the original router / AP can instead associate with the WLAN through the repeater.Suggested ReadingHow to Build a WiFi Home Network TutorialWhat Hardware is Required to Build a WiFi Network?What is the Range of a Typical WiFi LAN?Related ResourcesAbout WiFi Home NetworkingAbout 802.11 WiFi StandardsAbout Wireless Network SecurityRelated ArticlesWi-Fi Range - Which Wireless Router Has the Best Wi-Fi Signal?Wi-Fi Tip - Position the Wireless Access Point / Router for Best Performanc...How to Build a Wireless Home Network - Choosing Wireless GearWireless Range Extender - Range ExpanderAccess Point Definition

Follow me on:

FacebookTwitterDo you use Wi-Fi Internet at hotels around the world? A note this month from the Internet Crime Complaint Center (IC3) suggests you may be a prime target for hackers. Specifically, the IC3 is tracking claims that hotel travelers have had their computers infected with virus software that they unknowingly downloaded. This attack is sneaky in that people are apparently tricked to make the download by generating a pop-up window in the browser as soon as they initiate their Internet connection. While there are several ways to avoid falling into this trap, one good solution is to avoid downloading any software updates to your computers when traveling.

Here Comes 802.11ac (Wi-Fi Wireless Network Equipment)

By Bradley Mitchell, About.com GuideMay 20, 2012

My BioHeadlinesForumRSS

Follow me on:

FacebookTwitterWhich company was first to start shipping 802.11ac Wi-Fi gear to customers? The answer last week seemed to be Buffalo Technology who made their AirStation AC1300 wireless router and bridge products available for purchase on a few online outlet sites. Meanwhile, Netgear announced the R6300 router. Both company's routers technically support gigabit-speed networking, both featuring ratings of 1.3 Gbps (but being marketed as 1300 Mbps apparently in fear that customers won't be able to do the math).

802.11ac has been anticipated for several years as the next big upgrade in Wi-Fi networking. In particular, it's faster speed enables better high-definition video streaming across home networks, a capability that other wireless standards, even current 802.11n technology, have struggled to deliver.
