i have this modem from verizon, and we keep losing connection on it. i have contacted verizon like six times about the problem, and they even sent a tech to look at it. the dsl light will start flashing, and lose the connection for a minute or two, then come back up. verizon will just run a line test on it, but by the time we get them on the phone, everything is working just fine. does anyone have any suggestions on how to solve this issue?
