As per here, flashing orange/amber means the modem can't lock onto the downstream channel, which means it can't detect the signal sent over the coaxial for internet service. First thing to check is if the coaxial is screwed in tight and properly(not cross thread) into the back of the gateway and the connection on the wall. Next, try unplugging the power cord, wait a couple seconds, then plug it back in. If that doesn't work, check for outages and if you have TV service, if that works. Last, if you live in a normal house, how does the coaxial get from the pole/street to the room the gateway is in? Any splitters/amp/filter?
