How to Improve your Wi-Fi Network Connectivity when Network Connection Drops

How to Improve your Wi-Fi Network Connectivity when Network Connection Drops

By   21:02   1 comment:

May be your work location or in home or even sometimes in public wireless networks, your Wi-Fi connection might drop unexpectedly for no reason. This will be frustrating when you are in a hurry or when performing some important as well as urgent activity over the internet. It's also more common than you might think. Fortunately, we can fix this issue if you can follow this checklist to determine why it is happening and how to prevent it.

Position Your Router / Access Point for Best Performance

Radio signals from various consumer electronic products can interfere with Wi-Fi wireless network signals. For example, cordless phones, Bluetooth devices, garage door openers and microwave ovens can each take down a Wi-Fi network connection when powered on. You can move your network equipment or (on home networks) change some Wi-Fi radio settings to avoid this problem.

Insufficient Wi-Fi Network Range and Power

Even without interference from other equipment, Wi-Fi connections can drop occasionally on devices located near the edge of the network's wireless signal range. Wi-Fi links generally become more unstable with distance. Relocating your computer or other gear is a simple but not always practical solution. Otherwise, consider antenna upgrades and other techniques to improve wireless signal transmission and reception.

Unknowingly Connecting to the Wrong Wi-Fi Network

If two neighboring locations run unsecured Wi-Fi networks with the same name (SSID), your devices may connect to the wrong network without your knowledge. This can cause the interference and range problems described above. Additionally, in this scenario your computers will lose connection whenever the neighbor network is turned off, even if your preferred one remains functional. Take proper security measures to ensure your computers connect to the right network.

Network Driver or Firmware Upgrade Required

Each computer connected to a Wi-Fi network utilizes a small piece of software called the device driver. The Wi-Fi network device driver controls various functions of the Wi-Fi hardware. Network routers contain related technology called firmware. Network drivers and firmware can both become obsolete over time. Upgrading (over installing) newer versions of these things can sometimes fix network connection problems. Get free upgrades from the manufacturer's Web sites.

Incompatible Software Packages Installed

Wi-Fi network connections may start failing on a computer due to incompatible software installed and running there. This includes operating system patches, operating system services, and other software that modifies the networking capabilities of the operating system. Keep records of each time you install or upgrade software on your computers, and be prepared to uninstall any incompatible software you've added recently.

 

Overloading / Overheating the Wireless Access Point

Owners of some wireless routers (and other types of wireless access points) have reported dropped connections during times of heavy network utilization. This can occur during, for example, online gaming or while copying large files. Routers can, in theory, become overloaded with too much data and fail temporarily. If a router's temperature increases too much, it may also fail until cooled. Install routers (access points) in places with good airflow. Exchange the router for a different unit if the current one doesn't support your usage patterns.

If you still have issues, we suggest you Change the Wi-Fi Channel to Avoid Interference.

How to Change the Priority of Network Connections in Windows

How to Change the Priority of Network Connections in Windows

By   07:31   No comments:

Do you ever plug in your wired network card while your wireless card is still enabled? Ever wonder how Windows chooses which one to use? Here’s how to see the default priority—and how to change it if you want.

Note: there’s almost never any reason to change this, as Windows does a good job of choosing the right connection. Still, if you want windows to work differently with it, this is how you would do it.

How to Change the Network Card Priority

To change the priority, head into Network and Sharing Center and click on the Change adapter settings link on the left-hand side—or you can quickly open the network connections list by typing ncpa.cpl into the Start Menu search box.

From here on there are two ways to change this…

Method 1:

• press the ALT key on the keyboard,
• Then click the “Advanced” menu
• Choose “Advanced Settings”.
• In the window that pops up, use the arrows on the right side to move the Local Area Connection above the wireless connections.
• Click OK.

That's It.

Method 2:

Now that we’re in change adapter settings…

Choose the network card that you want to change the priority for, right-click it, and choose Properties from the menu.

Now select the Internet Protocol Version 4 item in the list, and click the Properties button.

Now click the Advanced button at the bottom of this window…. getting tired of clicking yet?

And now, finally, we’re at the place where you can make the change. Uncheck the box for Automatic Metric, and then type a number into the Interface Metric textbox. You can consult the list that we found in the command prompt earlier to know what metric to assign—you’ll probably want to assign it something higher than 1, since that’s used for the loopback adapter.

You may want to go ahead and change the priority for your other card as well, just to be sure that it is assigned the proper priority.

Differences Between Remote Networking And Remote Control

Differences Between Remote Networking And Remote Control

By   21:14   No comments:

When you connect to a PC using direct dial or virtual private networking (VPN), you’re simply joining the host’s network from far away. When you try to open a Word document that’s actually sitting on the distant PC, your laptop’s copy of Word opens and loads the file. Your laptop is doing the actual word processing; the host just sends and receives files as needed.

Windows’s Remote Desktop feature is a different animal. In this case, you’re using your laptop to control the host computer. If you double-click that Word file on the host computer, you open the copy of Word on the host computer. All the word processing takes place on the distant machine; all that passes over the connection between the two computers is a series of keystrokes, mouse movements, and screen displays. The host is doing all the work. Your laptop is just
peeking at the results.

Once you understand the differences between these technologies, you can make a more informed decision about which to use when. For example, suppose your PC at the office has a folder containing 100 megabytes of images you need to incorporate into a PowerPoint document. Using a remote networking connection means you’ll have to wait for the files to be transmitted to your laptop before you can begin working—and if you’ve connected to the office
machine using a dial-up modem, you’ll be waiting, literally, for several days.

If you use a Remote Desktop connection, on the other hand, the files remain right where they are: on the host computer, which does all the processing. You see on your screen exactly what you would see if you were sitting at the office. When you drag and drop one of those images into your PowerPoint document, all the action is taking place on the PC at the other end.

Of course, if the computer doing the dialing is a brand-new Pentium 7 zillion-megahertz screamer, and the host system is a 5-year-old rustbucket on its last legs, you might actually prefer a remote network connection, so the faster machine can do most of the heavy work.

Setting Up VPN Server On Windows XP

Setting Up VPN Server On Windows XP

By   12:12   No comments:

A VPN connection is a connection that is established using the Internet as the communication infrastructure for the connection, as opposed to a dial-up connection. VPNs allow the Internet to be used as a secure channel for communication with corporate networks.

One of the advantages provided by VPN connections is that they can greatly reduce a company's long distance phone bills while still providing secure remote communications. If the client computer's connection to the Internet is made using a broadband connection, the bandwidth available to the connection can make it many times faster than a dial-up connection. In addition, if a broadband connection is used, the user can remain connected for long periods of time without the worry of being disconnected, as is often the case with dial-in connections.

VPN connections are secured by encrypting data before sending it out over the Internet. The receiving computer on the other end of the connection decrypts the data back into its original format. Microsoft Windows XP Professional supports two different WAN protocols that can be used when creating a VPN connection.

The older protocol is the PPTP (Point-to-Point Tunneling Protocol). PPTP uses PPP-encrypted communications to establish VPN connections. Alternatively, the L2TP (Layer-2 Tunneling Protocol) can be used.

By default, this protocol does not encrypt data. However, it can be configured to use IPSec (Internet Protocol Security), which provides stronger security for VPN connections than PPTP.

Warning! Windows XP Professional can only support a single incoming connection. If a dial-up connection has already been set up on the computer, the connection must also be used to double as a VPN connection.

Setting Up VPN Server On Windows XP:

Windows XP Professional has the ability to act as a VPN server (in addition to providing a client VPN connection to a VNP server) that can support a single incoming VPN connection. While not generally appropriate for the corporate settings, this capability may be of interest to smaller companies or home networks.

The following procedure outlines the steps involved in setting up Windows XP Professional to act as a VPN server using an existing incoming connection.

Click on Start, right-click on My Network Places, and select Properties to open the Network Connections folder.

Right-click on the Incoming Connection and select Properties. The Incoming Connections Properties dialog appears, as shown in the screenshot below.

Configuring an incoming connection to accept a VPN connection

Select the Allow others to make private connections to my computer by tunneling through the Internet or other network option in the Virtual private network section.

Advantages of DFS Replication

Advantages of DFS Replication

By   16:22   1 comment:

DFS Replication, the successor to the File Replication service (FRS) introduced in Windows 2000 Server operating systems, is a new, state-based, multimaster replication engine that supports replication scheduling and bandwidth throttling. DFS Replication uses a new compression algorithm known as remote differential compression (RDC). RDC is a "diff-over-the wire" client-server protocol that can be used to efficiently update files over a limited-bandwidth network. RDC detects insertions, removals, and re-arrangements of data in files, enabling DFS Replication to replicate only the changed file blocks when files are updated.

DFS Replication uses many sophisticated processes to keep data synchronized on multiple servers. Before you begin using DFS Replication, it is helpful to understand the following concepts.

Figure: Configuring DFS Replication On Windows Server 2008

• DFS Replication is a multimaster replication engine. Any change that occurs on one member is replicated to all other members of the replication group.
• DFS Replication detects changes on the volume by monitoring the update sequence number (USN) journal, and DFS Replication replicates changes only after the file is closed.
• DFS Replication uses a staging folder to stage a file before sending or receiving it. For more information about staging folders, see Staging folders and Conflict and Deleted folders.
• DFS Replication uses a version vector exchange protocol to determine which files need to be synchronized. The protocol sends less than 1 kilobyte (KB) per file across the network to synchronize the metadata associated with changed files on the sending and receiving members.
• When a file is changed, only the changed blocks are replicated, not the entire file. The RDC protocol determines the changed file blocks. Using default settings, RDC works for any type of file larger than 64 KB, transferring only a fraction of the file over the network.
• DFS Replication uses a conflict resolution heuristic of last writer wins for files that are in conflict (that is, a file that is updated at multiple servers simultaneously) and earliest creator wins for name conflicts. Files and folders that lose the conflict resolution are moved to a folder known as the Conflict and Deleted folder. You can also configure the service to move deleted files to the Conflict and Deleted folder for retrieval should the file or folder be deleted. For more information, see Staging folders and Conflict and Deleted folders.
• DFS Replication is self-healing and can automatically recover from USN journal wraps, USN journal loss, or loss of the DFS Replication database.
• DFS Replication uses a Windows Management Instrumentation (WMI) provider that provides interfaces to obtain configuration and monitoring information from the DFS Replication service.
