We just had the same issue. RDK 03003 . 1 main big box in living room - Ok, 2 bedroom boxes - both have errors along with no ph or i'net either. Left 1 bedroom box unplugged all night. Next morning disconnected other bedroom box, bada bing! Works again. This seems to be a constant issue with this service. Becoming more than aggravating for a service you pay for + insurance for repairs, then they try to charge you for coming out to repair. Enjoy the services rendered, but personally it's not worth the cost or aggravation. Get with it Xfinity !!
