I just reformatted my computer and when I got to my desktop, I double-clicked Internet Explorer to download the latest drivers for my graphics card, chipset, etc., and it would not let me connect to the Internet. I have had the same setup for my network connection for 4 years and cannot seem to figure out what the problem is. I am using a Dell TrueMobile 2300 router which is connected from the Cable Modem -> Router -> My PC. I was able to connect to the Internet before I reformatted but Windows cannot determine my internet connection.
