TCP/IP or other parts of your network stack could be corrupted, running the command below would fix those types of problems.
Lets try flushing DNS cache and renewing your IP.
Flush the DNS cache and restore MS's Hosts file ...
Copy and paste these lines in Note pad.
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
Save as flush.bat to your desktop. Right click on the flush.bat file to run it as Administrator.
Your computer will reboot it self.
Rebooting a second time seems to help.
After that can you please post your ipconfig/all here. It may show some other problems that I'm missing at this point.
