Gateway down or equipment problems?

Greetings, first time using community and hopefully get assistance. My system has been down since Friday night, and called customer service this morning to determine the problem. My problem is there is no “System” light on the modem. All other lights are on. No internet or wifi working. Have done the usual, unplugged/plugged in modem, checked all coax connections, checked dish to see if it had moved, and called tech support. I can connect to 192.168.0.1 and it shows not connecting to Gateway. Signal strength is 92, state code 21.1.5. Tech support stated there is rain at my Gateway, San Diego, CA and is the problem. I don’t understand this as I have had my service for about 6 months and this is the first time having this problem. Is this to say it is the first time it has rained in San Diego in 6 months? And been raining for 3 days? Tech support suggested calling back tomorrow to see if they can help, but I’m not confident on their explanation today as to get any better answer tomorrow. Christmas is coming in a few days and my family will not have any internet or wifi at this rate. Have you seen this problem before? Could it be the modem or dish receiver has become defective? Any assistance is appreciated.
