i am unable to connect to the internet all of a sudden. last night it was working fine, i woke up and it no longer works. the pc hasn't been shut off in about 5 days. my first guess is there is something preventing me from getting on. i shut down all unrequired processes, was a no go. i checked to see if i had any weird connections, again a no go. i had been using a program called hamachi which is a program for connecting two computers so you can play lan games and the such. i had been running alot of different proxy servers and the such aswell. i have removed them all up to this point and still nothing. I connect via a USB cable to my cable modem. I plug the cable into the back of the case and it connects right away, there does not seem to be any delay connecting like there normally is. Checking the stats of the connection everything is blank, no ip address, subnet mask etc. If i try to repair the connection it says Failed to query TCP/IP settings. Hamachi did have a network connection setup and i noticed under device manager i had a "WAN Miniport" or something like that for both the RCA modem (that connects via usb) and the Dlink Gigabit network card i have. I removed all those and still nothing. I have tried using standard cat5 cable that i used to connect with and that didn't work either. My computer has 2 ethernet ports on it. One is built into my mobo and the other is the dlink gigabit network card i mentioned. The other only network connection i have is a VPN to my school.
I just tried connecting to the VPN and that wouldn't work. I then removed it and tried. One this that is curious is i disabled the Dlink network connection i was using to test and enabling it it said "no network cable found" and it never went away. Restarting the PC it would reconnect. I have used my laptop to connect to the cable modem fine, via cat5 and usb. My feeling is that there is something i installed that left some settings behind and thats preventing it from connecting correctly.
