Don’t panic if you can’t connect to the Orbi router; it's a common nuisance with a few easy fixes. To begin with, check if the power is on and inspect the Ethernet connections. Make sure your Orbi router is properly plugged into a power source and that the modem connection is secure.
Try now to powercycle both the modem and the Orbi router. Restarting machines often signals the end of any glitches experienced within the connectivity. Still unresponsive? Take a handy device, surf to orbilogin.com or 192.168.1.1 and find out if firmware updates or configuration glitches are there.
If a mindless blank is the only response, it means you are called upon to perform a 'soft reset': press and hold the reset button for 10 seconds. After the device restarts, recommence the connection of your devices. Meanwhile, do end up confirming that you are really trying to connect to the correct Orbi network (SSID).
These steps would get you back on the go quickly without having to call technical support when you cannot connect to an Orbi router.
