Tips to optimize your Network Connection and Wireless Connection
  

Many of you certainly have a network at home, and some definitely have problems when trying to connect away from the router or internet. To speed up your Internet connection, many parameters of the protocol can be optimized for Windows. TTL, MTU, RWIN, DNS cache, so many settings it is necessary to adapt to your configuration. These are the below tips to optimize your Wireless Network Connection:

Change the TTL

The TTL (Time To Live) is the maximum number of addresses (or routers) through which a packet can take to reach its destination. By default, this number is set to 32 addresses, which can be fair in some cases. Indeed, if the site you want to achieve required to go through 33 addresses (one also says that the package is 33 bonds), a message will appear telling you that the site is inaccessible as it really exists. It is therefore necessary to increase the TTL that you will set to 128, regardless of your Internet connection: dial-up, DSL or cable.

Improves the positioning of the router

If your router or access point is located on the first floor in a corner of the kitchen behind the fridge, buried under three weeks of daily and you connect from your laptop from your room on the second floor on the opposite side of the house, maybe you should consider the possibility of placing most of your Wi-Fi device. The positioning of the router is a crucial aspect that can greatly improve signal quality. The idea is to find a central point in which you want to cover maximum area. Also the area that you had selected is free objects that will obstruct the signal, such as closets or thick brick walls. Other devices that may affect the optimal functioning of your Wi-Fi are microwave ovens, cordless phones, remote-controlled devices such as gates or electric devices for remote monitoring (such as those used for children).

Update the firmware or drivers

Firmware update will boost the router output. It will also fix numerous bugs. This wll also improve performance and reliability, as well as adding new features. It's always a good idea to stay up to date with the latest releases.

buying the same brand devices

Compatibility can be a big problem, especially for two-way transmissions. May want to purchase the adapter and the router from the same company. Apart from this, some companies have implemented measures to improve the signal strength when all the communication partners are of the same brand.

Replace the antenna

Most routers have omnidirectional antennas, i.e. antennas that transmit the signal in a homogeneous and circular. This is perfect if your router is located at the center of the area that we cover, but it could be a waste if the router is located for example in a corner of the building (again, we can not find a better location?). The signal being transmitted radially, if the router is placed in a corner, most of the signal will be transmitted to the walls or the outside.You can then remove the router's standard antenna and replace it with a high-gain antenna. The antenna will use the energy to transmit the score in a specific direction. You may need to check and see if the router has an external antenna jack or plug.

Add an Access Point (WAP) or a repeater

You may need to add an Access Point or a signal repeater. If you plan to use a second access point, consider that you have to connect the primary router, connected to the telephone line for internet access, secondary access point via a network cable (Ethernet cable), another factor to consider in this regard is the cost, when a Wireless Access Point is more expensive than a standard wireless router. On the other hand, an Access Point has a flexibility that does not offer a standard router: can be configured as a gateway, bridge, repeater, or client. An additional access point allows the signal to replicate the primary router and extended in order to achieve greater coverage of the wireless signal. A wireless repeater works the same way.

change the MTU setting

The MTU "Maximum Transmission Unit" is defined as the maximum transmission capacity of "IP Packet" from the Internet on the network. It is measured in bytes. A lot of problems with connections or display certain sites or send emails with attachments that do not pass, or problems in FTP often come from the MTU value that is too large or too small. If the packets are too small, the items are more numerous and they are too large, shipments are slower.

The MTU is the maximum amount of information that can contain a packet of information that you send or receive through your line. Data sent over the Internet are transmitted packet (1500 bytes for PPPoA and 1492 for PPPoE). On a connection of poor quality, there are more lost packets that must be transferred back from the source. The idea is to limit the size of the lost packets that the source has the least possible data to be retransmitted. To limit the size of packet loss, you must reduce the size of the MTU. If you have a direct Internet connection (no modem router), the MTU is adjustable on your computer.

Re: Tips to optimize your Network Connection and Wireless Connection

These are the Tips to improve Network Connection

Enable caching of network files:
In Windows 7, the new function Transparent Caching keeps track of your computer all the files you have accessed another computer network and, as long as the files are not modified. You can work faster on shared files. Here's how to activate it.
  1. Click the Start button.
  2. In the Search field, type gpedit.msc.
  3. Click Edit Group Policy.
  4. In the window that opens, scroll down the option Computer Configuration, Administrative Templates, Network and Offline Files.
  5. Double click the Enable caching transparently.
  6. Select Enabled and click OK.
  7. Finally, restart your computer to apply the change.


Enable direct access to the cache
Windows 7, the function may allow NetDMA your network card to communicate directly with the processor cache on your computer without having to go through the system memory (DCA). This allows you to use less memory and reduce the latency of your transfers in large exchanges. Here's how to activate this feature.
  • Make sure at first that your hardware is compatible with NetDMA displaying the TCP. The line must be on state NetDMA enabled.
  • Click the Start button. In the Search field, type the command regedit.
  • Click the right mouse button on the program regedit.exe and choose Run as administrator.
  • Go to the HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, Services, Tcpip, Parameters.
  • Click the Edit menu, click New then DWORD Value 32 bits.
  • Name the new value EnableDCA and double click it.
  • Enter 1 in the Value Data field and click OK.
  • Close the Registry Editor and restart your computer to apply the change.


Enable overload control CTCP
To avoid network congestion, Windows defaults to former algorithms compatible with both low Internet connections and broadband connections. New algorithms suitable for broadband connections (ADSL and cable) are present in Windows Vista and Windows 7. You can enable to speed up data transfer over the Internet.
  1. Click the Start button.
  2. In the Search field, enter cmd.
  3. Click the right mouse button on the program cmd.exe and choose Run as administrator.
  4. In the Command Prompt window that appears, type the following command:
  5. netsh int tcp set global congestionprovider = ctcp
  6. Confirm with Enter.
  7. Close the Command Prompt and restart your computer to apply the change.

Reduce latency for games
When you play in a network (locally or on Internet), the latency is very important. It corresponds to the response time between when you press a button or move the mouse and when the desired action is executed in the game by default, Windows brings together in one small packets before sending them. By disabling this feature, small packets will be transferred immediately without delay, thus reducing your latency. Be careful, this can slow down your file transfers. To apply, therefore, when you want to network and to remove after your downloads. Note that this applies to Windows Vista (with SP1) and Windows 7.
  • Click the Start button.
  • In the Search field, type the command regedit.
  • Click the right mouse button on the program regedit.exe and choose Run as administrator.
  • Unroll the HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, Services, Tcpip, Parameters, Interfaces.
  • Then open {key} where NIC NIC is the identifier of your network card. To find the right key, open them all: it is that when your local IP address is specified (if you do not know, use the ipconfig command )
  • Click the Edit menu, click New then DWORD Value 32 bits.
  • Name the new value TcpAckFrequency and double click it.
  • Enter 1 in the Value Data field and click OK.
  • Then pull down the HKEY_LOCAL_MACHINE, SOFTWARE, Microsoft MSMQ.
  • Click on the Edit menu, click New and then Key.
  • Name the new Parameters key.
  • Click the Edit menu, click New then DWORD Value 32 bits.
  • Name the new value tcpnodelay and double click it.
  • Enter 1 in the Value Data field and click OK.
  • Finally close the registry editor and reboot your computer to apply changes.

Re: Tips to optimize your Network Connection and Wireless Connection

The three most common ways to connect to the Internet from home are dial-up, ADSL or cable. If you can choose, cable is usually faster, but both cable and ADSL is faster than dial-up.

Many Internet supply also offer Fiber Optic Service (FiOS) that connects to the Internet using light over an optical network. At home, still connected to the computer through copper wiring. The advantage of FiOS is that it can provide higher speeds than traditional cable connections of copper, such as DSL or cable. Some Internet supply offer several options, depending on the area where they are. It is more likely that the more populated areas have FiOS available. Contact the telephone company or Internet provider for more information.

If you use a dial-up connection, there are some ways to optimize your Internet speed. First, use a modem as quickly as possible. The modem is faster than send and receive information at a speed of 56 kilobits per second (Kbps). Most of the time you get a speed of 56 Kbps, but with a good telephone line can range from 45 to 50 Kbps.

Make sure the phone line is in good condition. If the telephone wiring in your home or office are old or damaged, this can have a poor signal or interference with telephone lines. Check your telephone wires to make sure they are not damaged, frayed or wrapped around electrical wires or telephone. If you experience choppy sound on the phone, it is advisable to contact your telephone service provider to check the lines inside and outside your home to determine if they are in good condition.

If your PC running Windows XP Professional or Windows Media Center then you can increase the speed of your Internet connection by about 20% with a quick and easy changes to the default configuration of the operating system. In fact, both versions of Windows in question are configured to reserve a portion of the available bandwidth for different services, update and monitor the presence of spyware. And 'possible to remove the constraint without causing any disruption or failure simply by doing the following:
  • Select "Start" => "Run ..." and in the text box that appears type "gpedit.msc" and then to enter;
  • In the "Group Policy" that will appears, on the left by selecting the folder "Administrative Templates", then "Network" and finally "QoS Packet Scheduler";
  • In the central part of the window, double click "Limit reservable bandwidth,";
  • Select "On" and when the section "Limit bandwidth (%)" write "0";
  • Select "Apply" and then "OK"
  • Restart the Computer

Re: Tips to optimize your Network Connection and Wireless Connection

Increase the power of the receiver, operating systems usually offer the possibility of increasing the power of the receiver installed on your computer, located by default at a low level to reduce the power consumption of laptops. The ways that vary from this configuration varies depending on operating system we use, but using the example of Windows XP: go to Control Panel> Network Connections and make right click on wireless connections, selecting Properties. Then select Configure ...> Advanced> Power Management, where we find the power bar that we want to put everything high.

The physical position of the router is key: It's the golden rule in dealing with the issue of wireless connections. Think that each wall that stands between the router and the receiving team will attenuate the signal strength, so it tries to position it so that it is as close as possible to all points where you want to get connection.

Keep up to date equipment: Make sure that both the firmware of the router, as the antennas of the receiving equipment of the signal are always updated with the latest version offered by the manufacturer. This recommended practice always help us get the most out of the equipment we are using. : so there is the possibility of interference between them if they travel in similar frequencies. Therefore, some devices allow us to choose between different frequency channels to broadcast the WiFi signal, which may be interesting to check to see if they offer better results in case of detecting low levels of signal.

Repeaters and new antennas: you still have problems to enjoy your wireless connection in certain areas of your home, then you may need to make any disbursement. One option is the signal repeaters, which require no configuration and help make waves reach a little further. The other is to change the omnidirectional antenna of your router, for a unidirectional antenna, concentrating its power to a single point. Choosing either option will depend on the particular situation of each house.

Repeaters on the market (also known as amplifiers or expander) that increase the coverage area. No need for drilling or wiring to place these devices increase the range. Are placed midway between the router and the area where we want to expand coverage. To communicate on the Internet, computers use the TCP / IP (Transfer Control Protocol / Internet Protocol). It cut all the information into packets that are then responsible for delivering to the correct destination, the router started carrying around the globe. Once at your destination, the packets are then grouped together to recover the original information.
