If Your Network Connection Is Not Configured Properly Or Has A Technical Glitch, You Will Usually See Some Error Messages On The Screen.
These messages provide helpful clues as to the nature of the problem, which you can use to get information about the cause of the problem.
You can use the following list of standard network error messages to troubleshoot network issues.
A Network Cable Is Unplugged
These messages appear in the form of a Windows desktop balloon. Various conditions, such as improper cabling or problems with the device drivers, can cause this type of error, each with its solutions.
If the connection is wired, you may lose access to the network. So it is better to solve the problem as soon as possible. If the link is wireless, your network will probably be working usually, but this error message will keep popping up until the problem is resolved and can be annoying to you.
IP Address Conflict (Address Already in Use)
If a computer is manually configured with an IP address used by other devices on the network, that computer (and possibly another device) will no longer use the web. This error is not very common and rarely happens. For example, configure two devices with the IP address 192.168.1.115. To fix this error, change the computer IP if the IP address is assigned manually. This problem can also occur if you give an IP with a DHCP service. Turning the router and then the computer on and off often fixes the problem.
The Network Path Cannot Find.
Updating the TCP / IP configuration can fix the problem when you plan to connect to another device on the network.
You may see this error if the time or date on the two devices is different or you do not have the correct permissions to access the resource.
Duplicate Name Exists on the Network
After turning on a computer connected to a local network, you may see this error as a Windows balloon message. If this happens, your computer will not access the network. Changing the computer name may fix the problem.
Limited or No Connectivity
When you open a website or network resource in Windows, you may get a pop-up error message that starts with “Limited or No Connectivity.” Resetting the TCP / IP stack is a common way to fix this error.
Connected With Limited Access
A technical bug in Windows causes this error message to appear when creating certain types of wireless connections. Microsoft fixed this problem in the service pack update for Windows Vista systems. You may still find this error in other versions of Windows, though. This error can also occur for different reasons in your home network that may require you to reset the router or connect and disconnect the wireless connection.
Unable to Join Network Failure” (error -3)”
This problem occurs if the wireless connection to your Apple iPhone or iPod touch fails. You can fix this error as you would on a computer to fix a failed Hotspot connection.
