I apologize in advance for the long rambling question,I understand next to nothing about computers. Our internet went out Friday night,I think they messed up a line when they were doing construction,but it was fixed on Monday. The modem shows that it's working,but when I first tried to connect it said "Windows can't communicate with the device or resource(primary DNS server)" I tried doing different things I found on some online forums http://answers.microsoft.com/en-us/windows/forum/w... then it changed and was saying "Your computer appears to be correctly configured, but the device or resource(DNS server) is not responding" I hooked up a different computer my Uncle gave me to try and see if the problem was just with the computer or the connection or whatever, and the internet didn't seem to be working on that one either. So I hooked the other one back up and then the computer was saying " "Wireless Network Connection" doesn't have a valid IP configuration" And a box popped up saying "Network Error-Windows has detected an IP address conflict. Another computer on this network has the same IP address as this computer. Contact your network administrator for help resolving this issue." I didn't do anything else, but the troubleshooting message went back to saying "Windows can't communicate with the device or resource(primary DNS server)" Wtf is going on?? The computer/internet/everything was working fine before it went out on Friday night, and my aunt who lives next door had her service come back just fine...
