Case solved ! Thanks to all for helping out with ideas and possible solutions ! Tried everything that was suggested, unfortunately did not help. So I looked back, and found that this pc previously had an AV installed (Norman Antivirus, not to be confused with Norton AV). It was uninstalled some time ago, but some remnants seemed still to be there. So I installed Norman again, then unistalled via Normans special uninstaller. And bingo, I had network connection ! The remnants must have blocked the connection. I should also mention that uninstall Norman via Revo uninstaller or Iobit uninstaller, would NOT solve the case. Had to use the Norman special uninstaller. Thanks again for all support ! Both wired and wlan have same problem. Connected to router. Another pc on same router with automatic,(ipconfig /all) gets ip192.168.1.224, gateway 192.168.1.1 Works fine. Problem pc with same setup, gets 169.254.32.162, active, but no network connection. Finds the network on wlan, but will not connect. Tried everything: Set static ip, same as on the other pc. (192......) Did not help Then: ipconfig /release and ipconfig /renew (this last one locks up.) netsh int ip reset c:\resetlog.txt Reinstalled lan and wlan driver. Nothing helps. Give up if no tip on this forum. Hoping for the best.
