@kristap That's a bit of an odd issue. If you're still seeing this behaviour, I'd recommend trying a factory reset on the modem, by using a pin or paperclip to press and hold the reset button on the back of the modem for 30-45 seconds, then allow it to boot back up. Once it's back online, run through the initial wifi set up again. I fyou encounter the same error again, connect with our technical support team here, so they can run some additional diagnostics on the equipment.
