Hi herff,
Welcome to Vista Forums!
This thread belongs to gebreab. What you have done is called hijacking and is discouraged. Among other reasons, it makes it very difficult for anyone to understand to whom replies are directed when we are trying to assist two different people in the same thread and can lead to misunderstandings that may result in either giving the wrong advice or someone doing something not intended for them (that may in fact even cause harm).
As this is your first time here, don't worry about it - it's no big deal. We'll help you, but first you need to start a separate thread in this forum. You do that by clicking the orange button at the top of the forum titled "New Thread." Name it whatever you want and then post your message.
From seeing what you posted above, we need MUCH more information to be able to help you. Although your problems may seem the same on the surface, the situations are most likely completely different. We need to know how your network is setup. Are you connected wirelessly or cabled? Was it working before and just stopped or is this a new installation? Can you ever connect or does it always give you "Local Only"? Are any other computers in your location connected the same way and are they working OK? What does "tried everything" mean - what EXACTLY have you tried and what happened when you did so? Are you using a router and, if so, what manufacturer, make, and model? If you have an intranet, can you connect locally to other computers or printers on the network? How long has the problem been going on even though you've been trying to fix it for a week? Is your network setup to connect to both the local network and internet simultaneously through the local connection or do you have separate connections for local access and broadband access? Add anything else you think might be of help.
I'm completely serious when I say that we need the answers to ALL of these questions before we can even get started. If I were in front of your computer, it would be much easier, but I'm not there, so I need you to do these things for me and provide me with the information I need to diagnose the cause and come up with a plan to resolve it. Perhaps the following article will also help you compose a good post that will give us what we need:
How to ask a question. I realize it will be a long post and take some time to compose.
Now, I'm going to give you some steps to do and include with that first post that will help us understand the problem better.
I'd like to try an experiment. Connect directly from the PC to the Modem (bypassing the router if it is possible to do this given the connectors - if not, skip the rest of this and the next paragraph) and then go to Start / Control Panel / Network and Sharing Center / Setup a connection or Network / Connect to the Internet / Broadband / Fill in the necessary information and then click Connect and see if you can connect. If it works, open your browser and verify it works OK. Then Go to start and shutdown the computer.
Now restart the computer. I'm not sure if it will start automatically or not as we really didn't set that up but it might. Go to Start / Connect To and check the available connections. Your local connection should show but be disconnected since we aren't attached to the router. Look at the broadband connection and see if it is connected or not. If not, then select it and click on Connect. Fill in the username and password if it wants it (it may or may not - we didn't configure that either). See if it connects. If the connection continues to work, then we know that the problem is with the router setup or the local connection (if the internet goes through it). Whatever happens (if it works or doesn't work), give me all the details in your next post. If it does not work, then go to Start / All Programs / Accessories / Command Prompt and double-click to open it. Type ipconfig /all and enter. Scroll so all the broadband connection information appears and take a screenshot and attach it to your next post. That should help me understand how it is setup and may show me where the problem is.
Reconnect the computer and modem to the router (or how it was setup before) and reboot. Then go to Start / All Programs / Accessories / Command Prompt and double-click to open it. Type ipconfig /all and enter. Scroll so all the local connection information appears (or the wireless connection - whichever contains more information) and take a screenshot and attach it to your next post. That should help us understand how it is setup and may show us where the problem is. Make sure you name the two screenshots so we'll know which is which and save them as .jpg files before you attach them.
I may see you when you repost or it may be someone else.
Thanks for your help and good luck!
