I've had Comcast HSI for about a week. Below are my modem logs. The modem is a Motorola 6141 connected to a Asus RT-N66U router. This equipment is Brand New. My home is 4 years old with RG-6/U cable to my modem. The installer told me I was the first house on the block and my signal was too strong. He installed a splitter and attenuation. I get several disconnects a day. The first few days seemed fine but the last 3 have been terrible. I'm using Windows 8 64 bit.
