For the last week or so, I'd been having trouble with my internet connection. I would lose my connection to the outside on a regular basis. It seemed to get worse over time. By Monday, it was only up for 2-5 minutes at a time. Each time I would turn off the cable modem and then turn it back on, I would get a connection for a while, and then it would cut out again.
After my third call to Cox Communications, it was explained to me that the Motorala Surfboard SB3100 was way out of date, and not supported anymore. Plus it couldn't take advantage of the higher speeds I was paying for anyway. So I ordered a new Motorola SB5120 and, voila, my internet connection is reliable once again.
