My Dell computer all of sudden won't connect to the Internet via a wired connection. In fact, there isn't a network icon showing up in the task bar, If I go to the network connections page, I will be presented with a blank page (and the device manager page is blank, too). I tried to reinstall Windows but I can't find the option to do that on the setup/boot menu (the one accessable by pressing F8 before going to the Windows screen upon startup). What should I do? Thanks.
Solved! Go to Solution.
Try "System Restore" and restore the PC to an earlier date. System Restore can be accessed from Start/Programs/Accessories/System Tools. System Restore will not delete any user data, e-mails, etc.
Depending on what happened the System Restore may take care of it.
The Dell recovery for Vista/Win 7 systems is F8 at Power On. At that same point you can press F12 for boot menu and for accessing the Dell hardware diagnostics (and it might be a good idea to run those since you are having problems).
If you are still having problems, post back and include the PC Model Number and OS. We can't give you specific help without that.

I tried system restore but it did not work. After pressing F8, I didn't see anything that said Dell or Dell hardware diagnostics after pressing F12.
Nothing is listed in Device Manager. No network hardware, hard drives, nothing. It's just a blank page. I can't connect via wireless either.
Did you recently "upgrade" your antivirus software? The symptoms that you have described are commonly the result of a Firewall blocking local network traffic.
If you don't think it is a firewall issue then why not start with the basics... what operating system do you have? Was it preinstalled on the computer or did you install it. was it installed from scratch or was it an 'upgrade' of an existing operating system? What more computer is it? Is the wired network card the only network adapter in the system? Is the network card integrated or an add on? Etc.
