Setting up your home network

How to change society and technology, an it/all for the home, to have more than one computer. When an existing computer for several years, parents will often use the today/to lower prices, buy a new computer and old to children.

Suddenly, there’s a need for a  home network so that all computers in the House to share a files, printers, and an Internet connection. Fortunately, setting up a basic home network is not a whole science. To start, you , you’ll need a router, which becomes the center point on your network. More office and online stores offer kits for home networking with a router, ethernet (network) and CAT-5 network cable.

If the team met in the past five years, you probably already have an ethernet adapter. Check the back of the system unit for a port that looks like a telephone connector, but slightly larger.

If you don ‘t have a  ethernet adapter, you can purchase one (about € 20) and install it yourself. You can also use a special ethernet adapter that connects to a USB port, if you can ‘t connect  the thought of opening your system drive to install an ethernet adapter.

Wired or wireless network?

You need to link each with  computer using a cable or go wireless. If you want to use wireless connections, you need  wireless router and the wireless network adapter for each computer. Most laptops have a wireless adapter built in, most desktop models do not. If you need a wireless adapter, you can buy one that installs inside the system unit or get a USB-style.

With a wireless network eliminates the need for unsightly cables in a string of all around the House, but it can also pose a security risk. Wireless networks often are configured by default to allow access to any computer that is trying to connect. Therefore, an evil hacker, driving with a laptop (or even your neighbor) may be able to connect to the Internet, or poke around the hard drive.

Fortunately, it is easy to set up security for wireless encryption. See my article Wireless Security for detailed instructions.

Network configuration

Whether network signals travel through a wire or air, network resources, still must be shared so that other computers can access them. If you are using Windows XP or MacOS X, everything you need to do is connect your computers and high-speed modems, and Internet connection sharing you simply work like magic. Otherwise, restart cable modem, router and computers (in that order), and see if it runs left. If you can — without access to the Internet from one or more computers on your network, refer to the manual included with the router.

To take advantage of the nice side of the router one is that they have built hardware firewalls. Firewalls protect networks from attacks that originate by hiding the computers but still allow Internet and e-mail. After you install a router, so you can turn off the Windows Firewall and any other software-based firewalls may need to be running.

Share files and printers

Share files and printers on a network Windows also very painless. To share a printer, go to the printers section of Control Panel, right-click the icon for the printer that needs to be shared, and then choose share the resulting menu. By specifying a name for the shared printer, the owner allows other computers on my network attempts to access the printer browsing using symbols network neighborhood (or my network places). Can only found on some computers or users through the use of options or security permissions on the shared screen.

The same concept applies to shared files and folders on a network. For example, if you want to share a collection of MP3 files on a home network, simply browse to the folder by using the my computer icon, right-click the folder name, and then click Sharing. After assigning a name to the share and set permissions, other computers on your network to access this resource via network neighborhood or my network places. CRM Software

There are a lot of errors, increase during startup. An additional, lesser-known improvements to the known, but they tend to double the speed when you start Windows. One of them is to remove the Windows boot image.

To start your computer, Windows displays the Welcome screen, but only download precious time costs! To avoid Windows to boot to this screen and expedite their seconds, start time is very simple. The file “boot.ini” only open Notepad or another editor for text and “//noguiboot”, after the “//fastdetect”.

In addition, the trend for windows uses IP addresses to paint if connected to the network at startup. This operation can take a long time. If you want to disable, you can assign a static IP address in this way is an attempt to get the default DHCP server IP. Displays a list of network adapters in order to achieve this, click Start, click Run, type “NCPA of CPL” and then click Run now. At this time. Choose the network adapter that connects to a local area network (LAN), and features of color. Click the right mouse button. Now a dialog box where you can specify the subnet mask for the IP address and DNS servers that should be. If the … do not know. Click Start, click Run, type cmd.exe/adversely affected ” and type ipconfig.exe/’, and this should have an entry for connect each network adapter.

This eliminates two Tweaks this starting point is due to two processes for quite a long time to complete the import process. Disable system services, and optimize your hard disk, you need a gift, and is known as assistance, access to the registry.

The quality of software enhancements and optimizations are more “settings”. Many of the tools, but because they contain summaries of the applications are easy to use.

The first thing to notice when discussing about securing a computer network is a network structure which will be implemented. Position the computer and other pieces of equipment is important, therefore, you must have a server and router, propagation environment and medium pieces of equipment that is placed in a place where administrators can access them and where users can access them, too. The main elements that you need to build a network depends on the company’s needs and preferences.

First of all, you have to select the required Internet connection in the network. The higher the traffic, the greater the bandwidth, but of course, the greater the cost, too. If You only need the Internet to check my e-mail, navigate through the browser or use other applications don ‘ t require  Internet connection-intensive, You can go for a simpler connection.

The main element of this puzzle is the server, and is therefore very important that make a good choice and buy a high quality product. Of course, all the pieces of the team are chosen finally according to the volume of data that mediate, reason why all options are on. Le shouldn ‘ t neglecting the less expensive pieces of equipment, such as passive elements, which would be the switches or cables. These pieces of equipment also play a very important role in the smooth functioning of your connection and network. Laminating Machine

Network your computer is not only on your computer, and digital devices to transfer data. These units different from the technologies used in different networks. But network equipment can be listed as a network interface card (nic), bridges, hubs, switches and routers. In addition to the Ethernet card may be requested. A common method used by the connection cable, optical cable, category 5. Microwave (as in IEEE 802.12), sometimes also used to connect these devices.

Network adapter

Network card, network card or network interface card (NIC to communicate with computer hardware) computer network. Physical access is provided by the device in a network environment. Most of the time, this is a low-level addressing system is a mac address. Repeater

Repeater signal noise, because of this, electronic devices, create and send a signal free from noise. Heavy duty remote wet signal may be subject to constraints without sacrificing performance. Academic development requires that more than 100 metres from the cable will also work in most twisted pair Ethernet configurations.

Hub

Copying more seaports axis at a later time without any changes by sending a packet to all ports on the hub. The destination address is not changed in the broadcast address.

Autumn

These ports are located on different network connections, network, with the exception of broadcasting never aired, which is the transfer of a copy of the door, but all of the MAC-address to certain ports that can be read.

Switch.

Turn off the filters for a piece of data packages for the MAC address of the port. Unlike the hubs by notification in the send port, the frames in all the ports that are connected to. A switch breaks up the collision domain, but is the field of broadcasting. Switching to the MAC address for the transfer of the frames. Each parameter is generally a large number of ports. This helps relieve the star topology of devices, networks and cascading additional options. Some switches are suitable for this routing.

Router

Network devices are routers route packets between networks. Packet redirection based on the information contained in the Protocol and forwarding table to the next router configurations are best for each package.

Installation and initial choice

You’ve got that new broadband line, ordered for your home or Office, but you understand that you want to be able to surf the Web, with a back yard or the meeting room that you forget to flood the wire. The obvious answer is to include wireless broadband in your order or your local computer store and buy a new “all singing, all dancing” wireless router.

But what is it that your wireless network safe and effective way to get this running on the bare essentials are Tail? Perhaps, it is very complicated and non-secure wireless networking. Maybe, but if you just can’t you open yourself to the rest of the world without realizing that you dont have to work your network already exists. n

At iOpening We don ‘ t think the technology is too complex and a few good tips, which we believe, that you will be responsible for some of the things yourself, you can make your life that much easier. The next few sections we can discuss some of the problems of the basic regulation, with  which you can reach out to the full in establishing the wireless network for the first time or when you “you have are one with the problems.

Get Connected

There is very busy in the suburbs, as well as local business districts. If you don’t believe me, if you have a wireless enabled laptop, just fire it up and have a look at your wireless network utility. You will find that wireless networks are just everywhere. You will probably see the BT HomeHub networks-xxxx, Belkin, Jones family, etc. Since local suppliers have given away wireless devices with their services, there has been a virtual explosion of wireless networks. This can be a problem as wireless networks communicate on a specific subset of radio stations and are limited to a range that can be used. Basically, this comes down to 11 useable wireless channels. The problem is that these channels tend to overlap a point and may cause interference with each other.

So what does this mean for you as a user? The choice of channel 11 impact the amount of access wireless signal, as they end up canceling each other. This can be noted, if you try to use the wireless network and find have a slow network connection wireless devices, loss of or inability to use the wireless network in different parts of your home or Office. The best alternative would be to select a channel in a wireless network is 5 channels away from Your neighbour. Now this can be difficult, may have several neighbouring countries using channels 1, 6 and 11 times by (if not other channels). How can this occur, the simplest approach is to select the channel that is already displayed a very weak signal wireless client and a 5 channels separately from the Strongest, La Paz network neighbors. After obtaining this blocked, will have to be the best signal, you can count on.

How will you actually get the best connectivity for wireless device in the home or business? In fact, a bit of trial and error, but fear not, there are some basic steps to show you the best performance without too much trouble.

o first create a good central location to install your wireless device. You want to make sure that you can get a consistent signal in your location.

o Consider building materials building is made of. Solid brick walls, stone and concrete can interfere with the wireless signal that radio waves, the bounce message with these solid material.

an attempt to place the wireless device in an enclosed space, how can it prevent the radio signal. If they are constrained by, where is your broadband connection and/or phone line, remember that you are always a cable to suitable.

or Finally, search for other devices which may affect its strength of wireless radio, such as certain 2.4 GHz phones, the constant use of microwave (if you eat a lot of leftovers) and other wireless devices.

Protect my network

Security or uncertainty factor for wireless networks has put you off many users of this technology. For the convenience of enormous and the availability of wireless technology today the issue of security was sometimes placed on the back burner.
Dont ‘ t ignore it – security is important and it will be a problem if you don ‘ t protect themselves. In addition, you Wouldn ‘ t leave your keys in the car and leave only a drive, would you? There are to a number of things you can do (free users) or hackers to get from the occasional offender wireless network protect.

First of all, make sure that the wireless device you select what you need. If you are looking for potential security basic  for your home, most devices will do the trick. However if you need a powerful firewall, logging, etc. You may want to consider a business-class device.

There are several key parameters, you can require that ensure your mobile phone safe levels. First you need to change the default settings to a wireless device. These provisions are, in General, the device name, user name, and device administrator details. There are so many wireless networks, which is installed in your default manufacturer  using names. It provides great, since it generally refers to the fact that the device is open and ready to attack, or may be unrestricted as the default unit.

This avoid, by first all change the device name to something innocuous such as 32skidoo or d3ltaEE. Make sure that you use a name that is connected, either to your address, business, or last name, since it won very well unwanted guests. Make sure that you the wireless name or the non-broadcast SSID-set up. This will stop the broadcast SSID for wireless clients and casual hackers will hold.

We provide the following basic security, it would have to apply any encryption. Both WEP and WPA has published the last hacks, but we recommend a stronger encryption. To contribute, inter alia, the WPA along better protected, such as the password security settings. Remember this mantra: change the password on your wireless device (and make it long and often change), password, change your Encryption (and make it long and change it often). If you stick to this method, it is possible to reduce the likelihood of a hack on your network.

You may have heard about using MAC address filtering. Each network adapter, such as wireless card has a unique ID, burned in is called MAC address. As it is, you can consider using MAC address filtering, to add another level of protection for your network. Using this level of filtering, specifically, you can restrict access to devices that you have added to this list. Finally, always use a firewall on your home and business desktops and laptops, as this is your last line of Defense.

If you stick to these basic steps, You will be able to enjoy your wireless network with the convenience of safe and affordable throughout your premises.

Today must take advantage of wireless technology and comfort.

Wireless advantage in terms of short-term projects, in particular cable Internet and computers, printers and projectors.

Wireless networks easier and faster configuration of wired network. Save time with wireless devices and wireless networks, flexibility. You can move your laptop. Projector and life estimation and remains good for all printers. Cable cat5, you do not need to run computer printers, routers, and switches.

Here are a few products, wireless, which usually means the undertaking of projects:

Rent a wireless router
