i once faced this issue, normal PC and one mac. our neighours are connected to our router and once we faced internet curruption. found out that they installed 4-port switch that cause this issue (IP issue).

if you have installed any devices lately, in which this problem appears after, remove them and try. you have to remember which date this was working .
