Have you ever been frustrated with home network setting? Definitely, I'm sure you have. Yeah, it's very easy to take a router or IT products from a store.But after that, setting up network may make you upset, you may be patientlessconfused and confused with the long instruction and using guide of the router. Just like these following friends: "How do you setup a Cisco Linksys Wireless N Broadband Router WRT160N V3?" "How do i hook my linksys wireless router up to my att modem?"  To set up your network, you need to know that how to configure proper IP addressing, lock down the network from intruders, create accounts for everyone who gets access, and set up sharing for files and folders and so on. Oh, it seems a little difficult to finish these tasks. It doesn't mattter, only easy five steps help you fix it.

Guide to Set Up Your Network:

 

Step one: Connect Your Router

 

The router is the gateway between the Internet and your home network. It is also the means by which all the devices on your network communicate with one another. In general, go with an 802.11n router for the best performance. You will also want to ensure that any device will connect to the router also has an 802.11n network adapter. These devices are your network "clients." New laptops and netbooks already have 802.11n adapters. For older laptops or desktops you can purchase compatible "n" adapters. Once you've got the right router, you have to set it up, and the first step is to physically connect your router to a modem provided by your ISP with an Ethernet cable. First, unplug or turn off the cable or DSL modem.Power up your wireless router and connect the network cable that most likely comes with it into the port on the router that is labeled "Internet" or "WAN." Connect the other end to the cable or DSL modem and power up the modem.

 

Don't attempt to connect any devices such as laptops or tablets until you have a good strong, signal indicating a WAN connection on both the router and modem.

 

Step two: Access the Router's Interface and Lock it Down

 

The next step involves getting into the router's interface (called by some companies the management console). This is done by connecting a laptop to the router and then accessing the interface via browser.Routers usually ship with a default IP address, administrator account and password. For example, most Cisco/Linksys routers have the default IP address of 192.168.1.1 and the default administrator account is "admin" and the password is "admin." What you want to do is to change your laptop's IP settings to match those of the router's to connect to it for configuration. This allows the laptop to communicate with the router, so you can access your router's software for setup via the laptop. Connect an Ethernet cable to one of the LAN ports on the router and the other end to the Ethernet port of your laptop. On a Windows 7 machine that's connected to the router by Ethernet, for example, you would go into the Control Panel and click open "Network and Internet" and then "Network and Sharing Center."...

 

Once you've applied the changes, open up a browser and go the Web address of (in our example,) the Cisco/Linksys' interface by typing: http://192.168.1.1 and using the account name "admin" and password "admin." Then you are all set to configure security and other settings.

 

Most router companies use the same default IP address, admin account, and passwords on all their routers. Here's a table of the most commonly used ones, but your router's documentation will tell you the specific IP address and account information.

Router Address Username    Password

3Com http://192.168.1.1    Admin admin

D-Link http://192.168.0.1     admin

Cisco/Linksys http://192.168.1.1 admin admin

Netgear http://192.168.0.    admin password

 

Step three: Configure Security and IP Addressing

The next step is getting the security, SSID and IP addressing settings right after you've accessed the router. You make all of these changes within the router's management interface. These settings are typically under the "Basic" settings of the interface. They may also be under "Security" or "Wireless Settings." 

Router interfaces vary, so check with the manufacturer if you can't find the settings to configure on the below steps within the interface pages:

1. Change the default administrator password.Some networking equipment forces you to do so, once you've accessed the Web-based interface, but many consumer routers don't. The settings for the admin password are usually under the "System" tab or area or page of the interface. You can just enter in a new password in the new password field.

 

2. Change the router's default SSID. The SSID is the broadcasted name of your wireless network. That's the name that shows up as the network's name when you scan for available networks. Use a unique name that your neighbors aren't using for their routers, to avoid confusion.

 

3. Assign security. Newer routers may be set by default to automatically configure security by using WPS (Wi-Fi Protected Setup).Some routers allow you to enter a string of 64 hexadecimal digits which provides strong security, but most have you create an 8 -to-63-letter passphrase. If you are creating a passphrase (or password) be sure to create a strong password that would be hard to guess.

 

4. Set up IP addressing. For most networks, the router can be kept at its default DHCP setting. This means the router will dole out IP addresses to clients that connect to the network, leaving you without any IP addressing management to do.  Remember, hackers know what the default IP address of the most common routers (even though it's really tough for them to get to due to the fact that your IP addresses on your network are private). For instance, I would change my Cisco/Linksys router's network from 192.168.1.1 to something like 192.168.1.3.

 

5. Disconnect the laptop and reboot it. When the laptop comes back from reboot you should see the SSID name of your wireless network and be able to connect to it with the passphrase you created. For those who anticipate connecting servers, NAS device or any device that you may access from outside your network, best practice is to configure DHCP Reservation. For example, my router IP is 192.168.1.1, I can give my email-server an IP address of 192.168.1.2. I can give a third device, say my NAS server for instance, an IP address of 192.168.1.3, and so on. 

 

Reserving IP addresses is good practice for devices you want to access remotely, because otherwise when the IP address leases expire you won't be able to perform remote access. Don't forget to assign the reserved IPs as static addresses on the devices for which you made reservations.There are various ways to do this, on Windows servers and machines you can assign an IP address though the Network settings Control Panel. Other devices, such as NASes, have areas in their management console where you can assign an IP address. It really depends on what device you want to set a static address for, so check with the vendor if you aren't sure.

 

Notice: If you are using the router as an access point, bridge or to extend the signal of an existing router on a network, you will want to turn off DHCP completely. Having two routers performing DHCP on the same network can result in myriad connection issues. However, for most home networks, having the router set to use DHCP will suffice.

 

Step four: Set Up Sharing and Control

 

Since you have a network set up, you can set up a way for everyone to access data on the network. With Windows 7 clients, this is achieved by creating a HomeGroup, a user-friendly way to create a workgroup. A HomeGroup is a group of computers on a home network that can share files and printers. Using a HomeGroup makes sharing easier. You can share pictures, music, videos, documents, and printers with other people in your HomeGroup. Other people can't change the files that you share unless you give them permission. You can help protect your HomeGroup with a password, which you can change at any time. Computers must be running Windows 7 to participate in a HomeGroup. HomeGroup is available in all editions of Windows 7. In Windows 7 Starter and Windows 7 Home Basic, you can join a HomeGroup, but you can't create one.

 

When a Windows 7 laptop first connects to the network, the user will be prompted to set the current network location. Ensure that the location is set to "Home network" (you can check it in Network and Sharing Center) because HomeGroup only works on networks set to the Home location.

 

Open up "HomeGroup" in the Control Panel, and then click "Create a HomeGroup." For every Windows 7 client that you want to give access to the HomeGroup, open HomeGroup in the Control Panel of those machines and then click "Join now" (those machines have to physically or wirelessly connected to the network).

 

During the process of setting up or joining a HomeGroup, you can choose the libraries, printers or files and folders you want to share. (see next step for details).

 

If you have a network with different version of Windows running, then you are going to create a standard Workgroup. Click Start, right-click My Computer, and then click Properties. In System Properties, click the Computer Name tab. Click "Change," select "Workgroup," and enter a workgroup name. Click OK to apply the change. Do the same thing for all computers that you want sharing data on the network.

 

Step five: Set Up User Accounts.

 

In most business networks, users access the network by logging in with their user account and password. Corporate IT networks set up user accounts to keep tabs on who is accessing the network and when they are accessing it. User accounts provide a way to establish user access control. Perhaps there's some data on the network some users should have access to and some shouldn't. Maybe some users should only be able to read certain files, while others should be able to change files.

 

You can establish this same kind of access in your home network, especially once you have a HomeGroup or Workgroup defined. It's quite easy to set up user accounts in Windows:

In Windows 7's Control Panel, select the User Accounts icon. User accounts will let you configure your account and its settings.

 

To add and configure other users, from User Accounts, click on "Manage User Accounts," and then click on the "Advanced" tab.

 

Under "Advanced User Management" click "Advanced" to open up Local Users and Groups.

Right-click on either "Users" or "Groups" to add either to your network.

 

If you have a number of people accessing your network and you want to control access to the data on it, you may also want to set up permissions for files and folders. Create a user account for every family member and then right click on the folder, click "Properties" and then the "Sharing" tab. You can add the family members that you want to give access to folder to and exclude the ones you don't. You can also right-click on each Library to select the specific users you want to share with. Right-click on a printers to pull up the "Sharing" tab to setup shared access.

 

Unless you have a lot of users connecting to your network, you most likely won't need to create user groups, but it's a good idea if you do anticipate a number of users connecting (like for a small business) and you want to give certain groups access to certain files and folders.

 

If you've gotten this far and performed all the steps that apply to you, you should have a functional, secure, and robust network set up. Of course, there are many other advanced steps you might want to take, such as setting up remote access, setting up port forwarding, automating backup across your network, or deploying a NAS. Stay tuned for step-by-step guides for all these networking tasks.
