We have roadrunner for our internet connection, and for about the last six weeks, we lose our connection about 6-7 times a day, but only for about 45 seconds at a time. I called Time Warner, and they said our signal strength is fine, and our modem isn't sending out any signals to them, so they see nothing wrong. He said I could bring the modem in and switch it out for a new one, but that sounded like a guess on his part. Any other ideas?
