Hello,
I'm configuring a new RUTX09 via WebGUI.
After changing LAN ex:
192.168.20.1 255.255.255.0
192.168.100.1 255.255.255.0
192.168.2.1 255.255.255.0
Via wizard or via configuration you loose connectivity, the router doesn't give DHCP anymore. I found a way to let it work again turning off the DHCP server, save and apply and then turning ON the DHCP server again save and apply. But this shouldn't happen.
