Router flashs blue light under the Telephone LED

[Erika_DSL_help]

I had a trip for a week. When I came back, I found I had no internet to access and the Telephone LED flashed blue in my Vodafone router. Others are normally flashing green lights. I don't know what happened and how to solve this problem. Please help me!
