Building a simple wireless network at home or office computer is easy enough to do little with the availability of various network devices, especially wireless router that has been integrated with the modem such as DSL-2640 D-Link or NETGEAR DGND3300. But sometimes it is not as simple as in theory, network problems often occur that force ourselves to do the network troubleshooting.
Troubleshooting network is doing a series langkah2 mostly to eliminate potensi2 problems one by one before we finally found the source of the problem. Basically there are three basic steps to troubleshoot a wireless network at home or at the office, namely: isolate the problem; troubleshooting problems; 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 his theory can be applied to a method of troubleshooting network problems in corporate networks as well. Generally on a wireless network at home or small office, there are three layers as shown in the diagram below, namely the Internet, modem / routers, 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 problems in the home network
Although we may be able to fix almost any network problems, knowing in the layer where the root of his problem is very helpful if the situation is forcing us if we need to contact technical support eg to the vendor or if it was stuck to the ISP can not fix it after we perform the network troubleshooting.
How do I know in the layer where the root of his problem, we can follow the following steps assuming our 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 NIC connection to the computer network adapter under the Network Connections window with the possible status as follows:
A> Status is Connected but can not access the internet
Connected Status
This status indicates that your computer is connected to the network properly, that is connected to the router / modem in the middle layer in the layer above the image. If the wireless network, the computer connected to the wireless router properly. This indicates there is a problem in the upper layer, namely the Internet.
To be able to perform network troubleshooting with this status, we can follow the steps below.
Make sure the first to open our Internet browser and check to certain websites such as only to www.computer-network.net or to www.wireless-router-net.com or wherever. If you can access the particular website but another good website, there are no problems on the side of your network. The problem lies on the part of an ISP which may be one of backbonenya damaged or broken. If at all you can not open the internet anywhere, continue the following steps.
Disconnect the telephone line to the modem or Cable line, wait a while for a minute and then connect again.
Unplug the wireless router from the modem (the connection between the LAN port on the modem and the wireless router WAN port), wait a while and then continued 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 can access the website but once the connection is slow while others can access the computer (if there are more than two computers in a network) you can suspect some other computers are taking a very intensive bandwidth may be streaming HD media from the internet or many make sharing files with multiple computers. the lid on another computer some suspicious applications and if necessary turn off while to make sure the problem. If none of the website opens, 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 internet access. If you successfully access to the internet, then you can be sure there is a problem with your wireless router.
If these steps still have not managed to access the internet, then certainly there is a problem with your modem or there is a problem with your P IS. Call your ISP to make sure if there is a problem with the Internet service.
B> NIC or wireless adapter disabled status
Disabled status
If the above picture is blurry status abu2 then ascertained that the adapters in the Disabled state. There is someone who inadvertently disabled downloading it or maybe you own a fraudulent attempt there click here and click Disable. Right-click the icon and select Enable.
C> limited or no connectivity status
Limited or no connectivity status
Conditions of limited or no connectivity 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 problem between the modem and the internet (if the parties ISP provides DHCP services to clients).
Troubleshooting a network with limited or no connectivity status is due to several different issues including the internet connection fails, the wireless router or adapter is not configured properly. Follow the instructions below for troubleshooting network with this status.
Right-click the adapter and select Repair. Consider whether it is a normal connected or still limited. This step ensures to obtain an IP address from the DHCP server.
Open the properties of TCP / IP on your adapter and make sure that the TCP / IP configuration is the Obtain an IP address automatically.
Disconnect the connection to the modem, wait a minute and connect again.
If there is a separate wireless router to the modem, disconnect the connection - wait a few seconds and plug it again.
Restart your computer
Until this step is still too limited status, then see if the router configuration or DHCP configuration was 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 the router continues to connect your computer directly to the modem. Restart the computer and check if the status has changed.
If it is still too limited status, contact your ISP. This status indicates DHCP failed function can not provide IP addresses to clients. Usually parties ISP provides DHCP configuration to clients.
D> Cable disconnected or loose
The status of the network cable is disconnected
This condition shows the wiring connections regardless, 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 how the port number to connect, usually light flashes if there is a connection to the wireless router / switch on the corresponding port.
If still disconnected status, try changing the network cable with a new one or try to borrow with a proven way cable from the computer side.
If the status is still disconnected, while other computers the way - then you can suspect a defective adapter. Replace with yangbaru.
E> Wireless adapter can not connect to wireless network
No connection 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 can not connect to your wireless network, or intermittent wireless connection

host1.e-padi.com
If Exit writing as above, shall mean the FQDN configuration is correct.
If still not out FQDN posts like the above, you should first set the FQDN in the / etc / hosts
# Cat / etc / hosts
# Do not remove the following line, or various programs
# That require network functionality will fail.
Host1 127.0.0.1 localhost.localdomain localhost
:: 1 localhost6.localdomain6 localhost6
Change into
# Pico / etc / hosts
# Do not remove the following line, or various programs
# That require network functionality will fail.
Localhost.localdomain localhost 127.0.0.1 host1.e-padi.com
:: 1 localhost6.localdomain6 localhost6

Passwd: (passwd root ssh)
-----------------------------------------
2. Install webmin manually via ssh
a. Open http://www.webmin.com/download.html find the right plan for servers
b. # Wget http://prdownloads.sourceforge.net/webadmin/webmin-1.510-1.noarch.rpm
c. # Rpm ivh webmin-1.510-1.noarch.rpm
d. If completed, access to webmin by: https: // IP_Mesin: 10000 /
Login: root
Passwd: (passwd root ssh)
-----------------------------------------
3. Install Webmin + Virtualmin manual
a. # Wget http://prdownloads.sourceforge.net/webadmin/webmin-1.580.tar.gz
b. # Gunzip webmin-1.500.tar.gz
c. # Tar xf webmin-1.500.tar
d. # Cd webmin-1.500
e. # ./setup.sh / Usr / local / webmin
-----------------------------------------
4. Install virtualmin / webmin with yum / repository
a. # Vi /etc/yum.repos.d/webmin.repo
b. Paste the code below gets under file /etc/yum.repos.d/webmin.repo
[Webmin]
name = Webmin Neutral Distribution
# baseurl = http: //download.webmin.com/download/yum
mirrorlist = http: //download.webmin.com/download/yum/mirrorlist
enabled = 1
Finish by saving the file in a way: "ESC +" type "wq!" + Enter
c. Download key
# Wget http://www.webmin.com/jcameron-key.asc
# Rpm --import-key.asc jcameron
# Rm -rf jcameron-key.asc
d. Start install webmin
