Posted on by

DLNA is a way of revolution can change the user to discover, download, store, send, printing digital content and game play. Some of these devices can connect and communicate with each other. What is needed is a network either wired or wireless. Just as broadband internet.

Digital Living Network Alliance (DLNA) initiated by Sony in 2003. From the beginning DLNA is a non-profit trade alliance has a membership of 250 companies. That DLNA is a standard-based technology used to facilitate the users to exchange content. Each device can give or receive photos, music, videos, etc. from one device to other devices that are both certified DLNA. Until the first quarter of 2011, already more than 9000 DLNA certified devices. More than 1000 television that has been verified DLNA.

Examples of application are: when you have a collection of movies stored in PC networks certified DMS (Digital Media Server). So instead of just watching the movie screen is a tiny PC’s monitor afterward you be able to send the film content to the LED TV in the living room. Obviously the LED TV has been adopted as a DLNA Certified DMP (Digital Media Player). So the film’s content can be displayed by that LED TV.

Nor may the case with music, when you make favorite music list into a PC network. When using DLNA Certified that can be certified as a controller of the mobile digital media (M-DMC), so you can find the song you want, then transferred and played on wireless speakers DLNA Certified.

Obviously daily increasing this DLNA certified products. So users are spoiled with the ease in selecting the preferred device. In enliven their e-life style. It’s a digital living.

Easy Steps to Network Troubleshooting | Part 2

In part 1 you have to prepare, create documentation, conduct a physical check, try to reboot and make the chronology of events. The following steps are the steps the next alternative.

 

Talking To User

Does the user have to change their system configurations? Installing new software? Do they use the new IP address? If the IP address that they take existing uses, then it could cause problems.

While identifying what is happening, try to think to happen outside the technical side. Human behavior may also be involved. For example, your colleague came after office hours with a laptop. Because no port is empty, he pulled out without telling. But he forgot to connect it back after the next day and you are shocked that the network be down. At first, of course you will consider this complex and mysterious.

 

Where Problems Arise?

Try to identify where problems arise. Is the problem appeared on only one application or all applications? Is the trouble only on one computer or all computers on the network also experienced the same problem? If only one computer, it stands to reason that the problem is the computer, instead of the network. Try restarting the system, and see if the troule still exists. What is the error message? Just look at the system log.

For example, suppose the NFS problem that we mentioned earlier. What just happened? Electrical surges so that all systems must be restarted. This means that the problem associated with all system restarts. Which applications are problematic? Only on NFS. All works fine. This means the problem is obvious NFS.

 

Use Ping

Still a problem? You do a physical check, it turns out all is fine. Among the network analysis tool, ping is the most useful tools. As you may already grasp, the ping can denote whether you can reach the connections on the other side, including computers, gateways, and printers. If you have, you will indeed be proficient to identify network problems and then find the solution.

 

Still Have a Problem?

The steps that have been done are adequate to conclude most of the problems, but not all. If you’re still having troubles, try to make sure the following points. Damage hardware: network cards, hubs, adapters and other components can be and sometimes are damaged. Try to identify the problem using ping and if necessary try to replace it with a hardware that is definitely working.
