Yes... on the bottom of your hub there's a tiny round network reset hole...
- If you are accidentally blocked from accessing your hub due to an incorrect or unknown IP address setting, turn the hub over and use the point of a pen to press the small button just beneath the surface of the hub casing for at least 7 seconds.
That should reset the hub's network settings (and that's all it resets) and allow you access again. Common practice is to use a DHCP reservation on your router rather than setting the hub to a static IP.
PS: It's the only round hole amongst all those square ones.
