This is horrible response and I've seen it given by other MS engineers. Thousands of people are having this problem since the 8.1 release. I highly doubt all of us had our routers go bad at the same time. Own up to this Microsoft and please fix it. The standard response will not cut it anymore.
This... Seriously,8.1 is garbage. I'm getting the idea that you chumps at Microsoft are giggling your asses off over all of these people struggling over this trash software.
