Essential Computer Network Repair TipsComputer network repair can be a pain, especially in the Windows XP operating systems while Vista and Windows 7 operating systems take time to get used to. Even if the easiest and most automated way to set up a network is used, problems can still arise and troubleshooting can be more of a hassle as the problem may lie on one or more of the computers. Knowing some of the essential computer network repair tips can help make repairs a little bit easier.
Checking all the Hardware Networking Components
This is a good step to perform first because it doesn't require any opening of cases if no problems are detected. You can tell if there are hardware problems simply by checking the "Device Manager" in the "System" Control Panel and see if the network devices are listed without any warning icons. If there are any warning icons, that should be the root of the problem and it can be solved by reinstalling the drivers or upgrading them. There could be a chance that the network device is disabled (shown with a red ‘X' overlay). Re-enable that device and see if it works properly and you might notice your connection restored. 
If there is no network device listed, there is something wrong with the network card. That is where you will need to open your system and see if the network card is properly seated. Try another LAN card from another computer and see if that works instead. If it does, you will need to replace that card before placing in the network. The whole objective of this tip is to make sure there are no hardware issues so you can focus more on the complicated Windows issues.
Checking the Connections
Your system tray should show a status indicator that tells you the status of the connection there could be a warning icon or red ‘X' icon if there is a problem with the connection. That could be caused by a loose cable, which you will need to check on all computers, including any routers or hubs that are involved. Make sure all the cables are connected in place and observe if there are any changes in status. If that doesn't solve the problem, try a different cable and see if the connection is restored. Do enough checks to the point that you can conclude that there is nothing wrong with any of the network cables.
Performing Windows Diagnostics
Now that you've gotten all the hardware stuff out of the way, you can now focus on the configuration parts where you need to get all the settings right to restore your connection. You can begin by restarting all the computers in the network and the router as well just to refresh the current situation. Identify the computers that are having network problems and do a repair by right clicking the connection activity icon found on the system tray and then clicking "Repair" or "Troubleshoot" depending on the operating system. 
If that doesn't fix the problem, then your network could be more advanced where you need to set IP addresses manually. Consult your network administrator for more computer network repair solutions that can fix those complicated issues. return from Computer Network Repair to On-Site Computer Repair
