hello, hours ago i was happily surfing the net, then suddenly now i cannot connect to the internet at allu; all attempts to load results in server not found. then i rebooted the router snd it still does not work. Then i also plugged the ethernet cable into the modem itself (the ethernet cable was supposed to be plugged to the router for wifi. if plugging the cable directly to the modem works, it's a problem with the wifi), and the connection still does not work; windows say that i was connecting into an unidentified network (had a bench near the connection) and i even tried the netsh commands and the connection still does not work. the light of my modem does not show anything weird on it; they are as usual, just cannot connect. and my device manager says that my lan card and connection ports have no problems. also, i had tried replacing my ethernet cable with a new one but it still does not work. totally stuck and lost, please help?
