How To Configure A Network Through A Router On Windows 7
Connecting computers to a network of the “computer-to-computer” type is certainly very easy to configure, but this method has several drawbacks, namely, computers can only communicate with each other. Based on this, we will not be able to use ADSL Internet and will not be able to connect more computers to the network. Therefore, you will get much more advantages if you immediately create a full-fledged local network using a router-router. This device has several inputs to which cables are connected. One entrance is the main, it has a WAN marking. The cable coming from the Internet provider is connected to this input. You must connect your computers to the free inputs. To connect, you need to use a cable with a normal crimp circuit. If you connect to the Internet through an ADSL modem, and connect to the Internet using a telephone line, then you can not mix up the connectors.
After you have connected all the cables, you can begin to configure the router. The fastest way to configure the router is to do it manually and there is absolutely nothing complicated about it. Setup is done through the web interface of the router. To enter the web interface, you need to enter the IP address of the router in the browser line, which in most cases can be found in the documents for your router. In most cases, this address is 192.168.1.1. After entering the address, you will be asked to enter your login and password. The default username is admin and the password is admin. After entering the login and password, you will enter the router settings menu. It is here that we will configure the router. Let’s get it in order.
The mode of operation of the router. Almost every router has the ability to work in several modes. For example, there are such operating modes as the “bridge” mode, in the settings of the router it is called Brige or the “access point” mode, in the settings – Access Point. Although on different routers, these modes can be called differently. In these modes, the router only passes all the information through itself, and all the settings will have to be entered on each computer separately. But we need our router to assign network addresses to our computers, scatter packets of data on destinations, etc. That is what he will do in Router mode.
Address Translation Mode (NAT). NAT mode is an address translation system. Thanks to this system, computers on your local network will be visible from the outside as the only computer with a single address. The NAT system distributes to all computers on the network internal addresses with which they can communicate on their local network. If you disable the NAT option, all computers will receive external addresses. In some cases, this is of course more convenient since with NAT enabled some exchangers or programs, such as torrent clients and others like that, do not want to work. But the main advantage of NAT is that some providers set a limit on the number of computers connected to the Internet, and NAT disguises all computers on the local network allowing them to use only one connection to the Internet provider on all computers.
DHCP mode. This mode is used so that your router can distribute IP addresses automatically to all computers on the network. This mode especially helps in cases where there are a lot of computers on the network and setting up on each computer is a somewhat problematic action. In some cases, it is necessary for a specific computer or several computers to pin a specific address. It may seem to you that it is impossible to do this in DHСP mode, but it is not so, you can add these computers to the exclusion list. The router will determine the computers in this case by the MAC address, which is recorded in the memory of each network card.
This address can be found out as follows.
1. You need to go to the panel on which the network card icon is located; in Windows 7, this is the Network and Sharing Center— View network status and tasks — Change adapter settings.
2. Now you need to click on the icon of your connection and call up the Status panel.
4. In the window that opens, you need to find the Physical address: The combination of six pairs separated by dashes is the MAC address of your card.
WAN and LAN settings. LAN is a local network and this section in the settings of the router is responsible for all the settings of the local network (internal network). As far as you remember, an external network is also connected to the router (the network of the Internet provider) and the WAN section is responsible for the settings of the external network. In this section, there are such settings as the DNS server, login and password, address, etc.
Wireless Mode Section. In this section, you can set up a wireless Wi-Fi network. This section is present on those routers that have a wireless interface in addition to a wired one.
