Here's how we'll tackle the problem:

When you have a problem, start by checking the basic internet connections. You can do this through basic Operating System trouble shooting. We will take you through that step by step process.

Next check if everything is connected properly. It sounds simple, but the slightest change can affect your service. Make sure your network adaptor connections and your Modem and Router are connected as they should be.

Finally, check on the network connection on the PC and its related parameters.

Here's how to do these 3 things, step by step.

If the status for the network adapter is unplugged:

1. Make sure that the network cable is properly connected.

2. If you find that there is no fault with the physical connections, check whether the modem and the router is plugged in and that it is turned on.

3. Try to plug the cable into a different network port in the router if available. If the network connection works fine, then it means that the previous port where the cable was plugged in is faulty.

4. Try to use a different network cable.

5. Try  to connect to a different computer using the same network cable. If the connection works fine then it means that the network adapter is not working. Contact the manufacturer of your computer for further support, or reinstall a new network adapter. If you are unable to connect to the network even in the new computer even after using a new network cable, the network hardware that you are using to connect the network cable to has failed. Contact the manufacturer of the network hardware device for further support.

By performing these steps you can verify whether the problem is with the router, modem or the Internet connection and fix the issue.

If the status for the network adapter is connected, but you are unable to go online:

1. Try getting online once more. Open internet explorer and try to access the following website: www.microsoft.com, and www.msn.com, if you are able to access this websites it means that the Internet connection is working fine. If you are unable to access this websites, perform the following steps.

2. Turn off the modem and unplug the modem that you are using to connect to the network and after one minute plug it back in again and turn it on. It sounds simple, but this reboots the device and usually clears a multitude of problems.

3. If there is a router connected to the modem, turn off the router and unplug the router from the modem and the computer. Wait for about 1 minute before plugging the router back in again and then turn it on.

4. Restart the computer, if there are more than one computer on the network, turn off all the other computers as well. Also, exit all  network applications process that is currently running like; file sharing and peer to peer applications. These will reduce the bandwidth of the network. Try to go online and check if the issue is resolved. If the issue is resolved it may be due to one of the applications that is causing this problem by increasing the use of the network bandwidth or it may because you are trying to connect to too many different computers at the same time.

5. If you are using a static IP address try to use an automatic IP address or vice versa and check if the issue is resolved.

6. If there is a router connected to the modem, turn off the router and unplug the router from the modem and the computer. Wait for about 1 minute before plugging the router back in again and then turn it on.

8. Try to connect the modem to a different computer if available, and try to access the Internet in the new computer. If you are able to go online the issue may be due to the Web browser that you are using. Contact your computer manufacturer for further support.

9. If the issue still persists contact your Internet Service Provider (ISP) for further support.
