Since my Router broke I have temporarily connect my PC directly to modem via ethernet cable. Internet and conncetion worked, but than I have some problems and type ipconfig/release and /ipcong renew and /ipconfig flushdns in cmd line. Now inthernet does not work any more. I restarted computer, try renew again, look for DCP client but nothing does not work. What can I do? Thanx for answers.
