If you’re having problems with setting your router up, it might be worth resetting it. Use a paper clip, pen, or something pointed to press in the reset pinhole button on the back of the router.
Keep the button pressed for 20 seconds. When the light on the front of your Hub turns green, release the reset button.
When the light on the front of the Hub turns blue, it’s now restored to factory settings.
Keep in mind that if you do this, it’ll completely restore your router to the settings it had when it arrived. So if you’ve made specific changes to your settings, they’ll need to be made again.
