No Internet connection

Hi

Today(25.02) in the morning my dsl internet stopped working. Tried all the required procedures, rebooted several time, etc.

The only two indicators blinking are power and wlan. Is there any downtime on o2 side? If there is no downtime on o2 side than it is ether my landline is dead or router fried it's brains.

Thought of reseting router to factory defaults but I have no PIN since I have never received a hard copy. Couple years back moderator sent me the PIN in PM but I can no longer find inbox in here.

Any help or hint how to solve is highly appreciated.

Cheers
