"No Internet Connection" twice a day.

For almost a year now since we moved to a new home in Victoria and got Rogers our modem loses internet connection about twice a day. The light stays on and white and wifi connections stay live but there's suddenly no data.

Is anyone else experiencing this? After a number of support contacts they just replaced the modem last week but it didn't do anything.

With modern devices it's so hard to troubleshoot anything. Beyond all the basic steps I'm not sure what to try (other than trying to get out of the 2 year commitment and getting on fibre).
