Verizon DSL is the Red Headed Step Child of the Verizon data handling world. My DSL modem frequently starts flashing the DSL light for a minute or two and then it returns to working. Other times the Internet light will go out and stay out for a minute or two, sometimes more.
Sometimes neither will reset on their own and I have to power down and power up the modem and things start working again. Sometimes the modem will work correctly for hours, sometimes minutes. Modem seems to work better when outside temperatures are lower. I currently have a small fan blowing A/C cooled air on it - it is working better this Summer with the additional cooling than it did last Summer, but it still fails much too often.
Fios is not offered in my area so that is not a option. The only other option would be to switch to COMCAST.
