connection issue at night on wii

For over a week netflix keeps showing "unable to connect, try again or exit" . This only happens at night though. I have deactivated it on my Wwii and reloaded it, that didn't work. If I hit "try again" enough times it will sometimes work, but then I have issues loading certain shows. I am beyond frustrated with netflix at this point and don't know what the next step is or how to make this actually work!!!
