My computer won't connect to the Internet

I have two desktops and on laptop. One DT is connected by Ethernet, the other DT and LT are wireless using the modem/router (2wire) connected to the 1st with the ethernet. I went to work on my ethernet DT (work from home) on Thursday morning, and was having trouble with opening their phone panel (it's a panel that I open on the work website to receive calls from customers). It wouldn't completely open, and that has happened before (not just to me but every agent), so I cleared my java cache, deleted browsing history, and restarted the computer. When I restarted, I could not connect to the internet. However, my other DT and LT both can connect without a problem. I called my internet provider, went through a bunch of things, and when in safe mode, could connect, but when in "regular" mode, cannot connect. They determined it was a problem with my computer, since the other two wireless computers are working fine. She suggested that I look and see if any new software had been installed. A windows update had been installed the night before (Silverlight), so I uninstalled that and rebooted. Still a no go. Then I restored the computer back to a week before and re-booted. Still a no go. We have had problems with this computer before (very slow), but the funny thing is that in the past 2 weeks it has acted normal and opened up as quickly as the other two computers, even though it has been slow for years. I'm thinking it's time for a new computer, but thought I would check on here to see if you have any suggestions Thanks!

Welcome to Geeks2Go!

It could be the network card inside your DT that the ethernet cable is connected to that's causing the connection problem.
Either it's driver is missing or corrupted, or the card itself has failed.
Any problem with the either the network card or it's driver would not prevent wireless internet from working on the other computers,
which is why I believe the problem lies within your DT that's wired to the router.

For confirmation of a driver problem, check in Device Manager for any tell-tale error symbols, and if you see such confirmation, download new network driver from the DT manufacturer's website.

If it's not a driver problem, replace the network card.

Very rarely, it's a faulty or broken ethernet cable, so you may want to change that first, just in case. But, as I say, a faulty ethernet cable is uncommon unless it's had some rough handling at each end.

If you can dumb your response down for me, I would appreciate it. Really, I am a dummy when it comes to anything technical with my computer.

I did find Device Manager in Control Panel, but I don't know what any tell tale signs are...what am I looking for?
Maybe this? I see one yellow triangle with an exclamation point next to "Teredo Tunneling Pseudo-Interface" (under Network Adapters), but have no idea what that means. I did click on it and the pop up box says "This device cannot start (code 10). Click "check for solutions" to send data about this device to Microsoft and to see if there is a solution available." I clicked the "check for solutions button", it says "Could not load driver software, windows is checking for a solution", then the box closes and nothing happens.

How would I download a new network driver? Would I just go to HP's website (the type of computer I have) and it will tell me? And how can I do that if the DT will not connect to the internet?

How would I replace a media card? Is that something that I have to buy at the store and would it explain how to replace it?

Thanks so much!
Michelle
