I also have a SB6190 modem. I live in the North West section of RI. My internet download speed used to always be around 330 average down and upload 31 average. About 4 days ago I did a speed test and the download was around 250 and upload was between 3-6 . I called in for service and they could do nothing over the phone. They scheduled a tech to come in 3 days. Later that night my internet speeds returned to normal 330/31. I waited 2 days and all was good. I cancelled the service call. Don't you know the day the tech was suppose to come the internet speeds dropped off again.
About a year ago I had problems. They told me it was my modem. I was about ready to buy another modem when it started working again. I call in and they told me their was a outage in the area. I would not have been happy if I bought another modem. Its been working fine for a year until a few days ago.
