When I play Overwatch I often experience severe ping spikes past the 1000ms mark. I usually have consistent ping at about 40ms WITH an ethernet cable yet I still get these ping spikes. I mainly notice the spikes at about 3:30pm pretty much on the dot, onwards randomly till about 12:30 am when the last spike happens and then stops, and the spikes last anywhere from 10 seconds to 2 minutes. I live in Australia and have NBN connection. No one else is using the internet at this time. Please help me fix this problem although I'm not very knowledgeable about internet configuration. Thanks in advance
