Intermittent internet connection drop outs

Hi,

Over the last week we've been experiencing intermittent internet connection drop outs.

I have tried resetting the router while running the online diagnostic test, but the problem persists. Please see the network logs and diagnostic information below.

Any help with this would be greatly appreciated

Kind regards,

Andrew
