Isokolon :
see if you get a valid IP address asigned by the router (for example by ipconfig command in command prompt)
this issue mostly happens when there's no correct IP configuration
if you don't get a valid IP you gotta do the settings manually, filling in ip-adress, gateway and DNS-servers in the network adapter properties
I got this when I opened the command prompt.
