Can't connect with fixed IP, only DHCP works
Working on Win7 Pro x64 for years with same network settings - gigabit wired IPv4, fixed IP, fixed DNS, etc. Lot of other comps, network printers, APs - everything works fine. Suddenly last week my machine (only one) refused to connect - sometimes with yellow exclamation triangle on network icon, sometimes w/o it. But even if it tells "connected to internet" it does not connect to anything, even gateway. Few times it was resolved by reconnecting network cable. Trying various solutions without success. Then I noticed, that changing IP settings to DHCP solves problem - connection is back. Reverting to old fixed IP "disables" connection. I didn't install any new hardware or soft, only periodical software updates. Restoring system from "working" image made nothing. Have no idea - what's going on? Any way to fix or check what is a cause?
