Blinking Red/Green Broadband light


Blinking Red/Green Broadband light

I ordered U-verse (self install) and followed all the directions i was given. My internet service was set to start yesterday, so that shouldn't be an issue. I live in a house, not an apartment building.  Everything is plugged into the correct place, but i haven't been able to get it to connect at all. The broadband will blink green, then blink red, then green, then red ect... and never connects. What does that mean?

Re: Blinking Red/Green Broadband light

Hi a.calabresecain,


I am so sorry about the issues you are having trying to get your U-verse services installed. When you have a blinking Red broadband light, it means that it is not getting a connection. With it going back and forth, it seems like it is seeing our end and attempting to get a connection, but it is not getting through. 

You just want to check a few things:

  1. Try using a direct connection with the equipment provided to the phone jack, so no filters or splitters.
  2. Try different phone jacks in your house
  3. Reset the U-verse modem by pressing and holding the reset button for 10 seconds.

I will also be sending you a private message, so if you still notice it not working after that, we can assist by getting a technician out.
