Building
a simple wireless network at home or office computer is easy enough to
do little with the availability of a wide range of network devices,
especially wireless router that is already integrated with the modem
such as DSL-2640 D-Link or NETGEAR DGND3300. However,
sometimes it is not as simple as in theory, network problems often
occur that forces we ourselves must perform network troubleshooting.
This job is mostly a series of steps to eliminate potential issues one by one before we finally found the source of the problem. Basically there are three basic steps in troubleshooting the wireless network at home or at the office are: isolate the problem; troubleshooting the problem, and if necessary contact the appropriate technical support.Isolating Problems
Before troubleshooting the network, we need to localize or isolate what is at the root of the problem. This article is devoted to the wireless network dirumahan or small office, although the theory can be applied to a method of troubleshooting network problems in the corporate network as well. Generally on a wireless network at home or a small office, there are three layers as shown in the diagram below, the Internet, modem / router, and computers on the network. We should be able to isolate in the layer where the problem is before we perform network troubleshooting effectively.Network layer for insulation in the home network problems
Network layer for insulation in the home network problems
Although we may be able to fix almost any problem network layer know where the root of its problems is very helpful if the situation is forcing us if we need to contact technical support to the vendor or for example if it was stuck to the ISP can not fix it after we perform network troubleshooting.Determining layer problem
How do I know in the layer where the root of its problems, we can follow these steps assuming your computer using Windows XP / Vista.
Click Start => Control Panel => Click Network and Internet Connections
Under Network and Internet Connection => Click Network Connection
Now we can see the status of the connection NIC network adapters on the computer under the Network Connections window with the possible status as follows:
A> Status is Connected but can not access internetConnected Status
Connected Status
This status indicates that your computer is connected to the network properly, which is connected to the router / modem in the middle layer above the image layer. If the wireless network, the computer connected to the wireless router properly. This indicates there is a problem in the layer above the Internet.
To be able to perform network troubleshooting with this status, we can follow the following steps.
Make sure in advance with our open internet browser and check to certain websites such course to www.computer-network.net or www.wireless-router-net.com or wherever. If you are able to access a particular website but the website will be another good, there are no problems on the network. The problem lies in the hand that ISPs may be one backbonenya damaged or broken. If at all you can not open the internet anywhere, continue the following steps.
Unplug your modem to the phone line or Cable line, wait a while for a minute and then connect again.
Unplug your wireless router from the modem (the connection between the LAN port on the modem and the wireless router WAN port), wait a few moments and then connect again. This is if you have a separate device between the wireless router and modem.
Restart your computer and repeat to open and access the website. If you are able to access a website but the connection is very slow while others could be accessing the computer (if there are more than two computers in the network) you might conclude that some of the other computers are taking very intensive bandwidth may be streaming HD media from the internet or do a lot of sharing files with some computers. the lid on another computer several suspicious applications and if necessary turn off temporarily to make sure the problem. If none of the website is open, then perform the following steps.
If you have a separate modem and wireless router, try to disconnect the connection to the wireless router and connect your computer directly to the modem. Restart your computer and try again with internet access. If you're successful access to the internet, then you can be sure there is a problem with the wireless router.
If this step is still not managed to access the internet, then surely there is a problem with your modem or there is a problem with your P IS. Call your ISP to ensure that there is a problem with the Internet service.
B> NIC or wireless adapter disabled statusDisabled status
Disabled status
If the image is blurry abu2 status above it is ascertained that the adapter in a state Disabled. There is someone who inadvertently disabled download it or maybe you own a fraudulent try clicking here and there and click Disable. Right-click the icon and select Enable.
C> limited or no connectivity statusLimited or no connectivity status
Limited or no connectivity status
Conditions of limited or no connectivity is basically no problem with your computer, connect to the router or modem is also no problem, but the configuration of the wireless router is not perfect. It is usually associated with the DHCP configuration on the router is off or there is a connection between the modem and the internet (if the parties to the ISP provide DHCP clients).
Troubleshooting network with limited or no connectivity status is due to several different problems including a failed Internet connection, wireless router or adapter is not configured properly. Follow the instructions below for troubleshooting networks with this status.
Right-click the adapter and select Repair. Consider whether it is connected or is limited to normal. The move is sure to get an IP address from the DHCP server.
Open the properties of TCP / IP from the adapter and make sure that the TCP / IP configuration is OBTAIN IP address automatically.
Disconnect the modem, wait a minute and connect again.
If there is a separate wireless router with a modem, disconnect the connection - wait a few minutes and connect it again.
Restart your computer
Until this step is still too limited status, then see if the router configuration or DHCP configuration is already enabled.
Restart your computer. If the status is Limited or no connectivity, and if the wireless computer and a separate modem, try to disconnect the modem and router continued to connect your computer directly to the modem. Restart the computer and check if the status has changed.
If still limited status, contact your ISP. This status indicates a failed DHCP function can not provide IP addresses to clients. Usually hand ISP gives DHCP configuration to clients.
D> Cable disconnected or looseStatus of the network cable is disconnected
Status of the network cable is disconnected
This condition indicates a cable connection apart, there is no connection to the router / modem.
Check if there kebel apart
If the cables are connected perfectly to the router / switch, try to swap to another port on the router / switch. You can also check the status lights on the router or switch when the cable is connected to the computer port number it is connected, usually light will flash if there is a connection to the wireless router / switch on the port in question.
If still disconnected status, try changing the cable network with a new one or try to borrow a cable from the computer proved to be the next.
If the status is disconnected, while the other computer - then you might conclude that your adapter is damaged. Replace with yangbaru.
E> Wireless adapter can not connect to the wireless network
This shows the connection status of your wireless adapter is disconnected with your wireless network. There are two possibilities, your wireless adapter could not connect to your wireless network, or a wireless connection intermittent.
