Cannot get on the internet ,network adaptor is not working
First you want to make sure that you network adapter is truly not working and if not what part of it isn’t working.
First we need to check some settings. Open the start menu and then network connections, then show all connections. Some computers have been configured with out this option set, so to get to the open the “My Network Places” the on the right hand panel click “View Network Connections”. Insure that the network adapter that you use to connect to the Internet is enabled. If it is then we will move on, if not then double click the icon and it should enable the adapter (check to see if you can connect to the Internet).
Moving on, open the start menu and click the run button. In the box, type cmd.exe and hit enter. At the command prompt we will enter some commands to find out where the problem is. First type “ipconfig” and hit enter. If your IP address (the first IP address listed) is ok (anything not starting with 69) then that part is working on and we will have to move on. Next type “ping 127.0.0.1” and hit enter. This tests your operating system to see if it’s working. If you get a response then the problem isn’t your OS. If you get an error then we will need to trouble shoot that later. Now type “ping” then your IP address; this tests your network card to see if it’s working correctly. If you don’t get an error then you network card is working. The last command will test your network, type “ping” then your default gateways IP address. If you don’t get any errors then your problem might be with the network configurations in your router or you ISP.
If your IP address starts with 69 the there is something wrong with the way your computer is getting its IP address from your network. One easy way to fix that is to force it to accept a different on. In the “view my network connection” box, right click on the network adapter icon the properties. In the center box, scroll down to the internet protocol (TCP/IP) and highlight it the click the properties button. In the following box select the “use the following IP address” button. In the IP address area type “192.168.0.1” then hit tab and enter “255.255.255.0” the click ok. Now go back to the previous box and click the “obtain an IP address automatically” and click ok. Now try to connect and see what happens.
If you received an error from your ping test (127.0.0.1) then you need to reinstall the TCP/IP stack. To do that, all you need to do is highlight Internet Protocol (TCP/IP) and click uninstall. Then click the install button, locate the Internet Protocol (TCP/IP) and then click install. Try to connect and see what happens.
If you received an error from your ping test (your IP address) then you can assume that your network card is bad and should buy a new Network Interface Card (NIC) at your local computer store. To install it, turn off your computer and you remove the screws (or push a button on the back of the computer depending on you computer). If you’re looking at the back panel it should be on the left side. The card should snap into place and install automatically. You should install any drivers that came with the hardware to make sure it operates properly.
If you got an error from your ping test to the “default gateway” then you network hardware is having problems. Try unplugging everything plug it back in. You need to make sure that you plug the modem in first and insure that all the lights turn green before you plug your router back in. If that doesn’t work you will need to replace your network hardware.
The last thing that it could be is your firewall. For that you may need to contact the manufacture to get proper configuration information.
If you’re still having problems, post a comment.
