yes, correct, we get this IP directly through our ISP by WAN (eth1) port.The public address routerWAN_IP is directly on this router (you'd see it in IP->Addresses), not on some other router, modem or whatever, right?
Actually going to bring it back to reseller, and try to manage this with him. I`ll update later what was the issue.Hmmm, try to use RS232 serial port !
It was, but before I created the forum topic, I have disconnected all other peripherals (it was LTE PCI-E)Is there plugged any additional peripheral devices - wifi, Lte pci-e card or usb etc...If answer is Yes, remove them and try again .
Already did this, holding reset button when starting the router, green led starts flashing, that letting reset button.Reset the router and try again !
