No address from dsl on router

[plume_canel]

Hello,
I have wireless router and my DSL internet cable in pluggeg in the wan slot.
Everything was working fine, all the LED were on and flashing and I had my connection to the Internet.
For some reason I obviously don't know, my router and my DSL modem are not talking anymore.

My network is working fine but I can't get an IP address from my DSL modem so no connection to the internet.

If I connect directly on the computer everything works fine

Usual advice is to restart router and modem together.
