wan light did not work

Hello everyone,

I just apply for a new internet connection with O2, however, after the technician come and set up the line, my internet still can not work.

I use my own router to connect, but the light of WAN did not turn on, so that I can not do any setting with it.

I also have some questions about the connection, is the username and password on the welcome letter for the PPPoE settings?

How to fix my WAN problem?

I heard that I need to follow and PM@o2_Stefan?

Thx for the help!!!
