Problem Connecting and Internet Network Solution

1. Network problems because of the failure of a network cable
Which is a common network problems we encountered due to the broken network cable that can affect the performance of a computer in the network because your patch cable cuts because bitten by rats; network problems that impact on a building block for inter-switch cable cuts (uplink cable); or even have an impact on most of the computers in your LAN network for backbone cable failure.

2. Network problems because of the failure of a network device
Scale disturbances result from the failure of a network device can also vary, from just a computer because of the failure of NIC - lan card; some computers because of the failure of a switch; or even a large scale because of the failure of the central switch that connects a network server. For failure lan cards in one computer can be replaced with a backup of your network card.

3. Network problems because of the failure of the system
The failure of the system could be because there is a problem with your DHCP server so that clients do not receive an IP address. Or it could be because there is a problem with your system so that clients Directory Services could not logon to jaringan.Atau could be due to a problem with the register name on your DNS system.

4. Network problems due to blast virus
This species is also a network problem that is not due to the failure of the physical network infrastructure, but the system will be overwhelmed with traffic your network of influence of viruses that attack and infect the server system to all computers in your network. The performance of your network system will be extremely slow even arguably collapsed. What can you do with this virus attack is to implement best practice security policy, you should be immune defense system once.

5. Connection Problems dashed
Cause: The quality of the telephone network decreases, telephone voice kemrosok or no hum
Solution: - Check the wiring of the house (from KTB up Modem)
- If you still try to report to the office nearest TELKOM

6. Slow Connection Problems
Cause: The number of shared PCs.
Activity Client-client PC Download or Upload Malware (Viruses, Trojans, Spyware) who spend your bandwidth Indeed Conditions Slow PC
Solution: Use Bandwidth management Use antivirus or anti spyware

7. The problem is on the Network Connection
  where the number of IP, Gateway dllnya nge-blank, but already in the manual settings, connected network status and still be able to access the data network via IPX / SPX / NetBIOS, but its IP number can not access the internet then stays off.
solution:
Error 1068: The dependency service or group failed to start. DHCP Client Service on Windows XP depends on the following three components: * AFD * NetBIOS over Tcpip * TCP / IP Protocol Driver If one of the above drivers fail the road, then the DHCP Client Service will fail way / not start.
Step I - Make sure that all three of the above driver files are in place Open Windows Explorer navigate to the folder% windir% \ System32 \ Drivers. Make sure the following files exist in the folder: * afd.sys * tcpip.sys * Netbt.sys
If one or more of the above missing files \ no, extrakkan from the Windows XP CD-ROM or from a folder ServicePackFiles \ i386. ---> What I do is unite from another computer that Windows XP it is still OK.
Step II - restarted Simple TCP / IP dah normal street and internet connection.

comment:
 
In a process that is on a computer network is not entirely due to provider error, but no human or human element itself is not careful in connecting to the Internet, for example:
1. Failure on the cable network bitten by rats
2. The number of users or clients that redundant data download
3. And the disruption of computer devices
We should be more careful.
