DSL didnt works after Upgrade

Installing and Using OpenWrt
1

Hey,

I have a r7800 and updgtaded from openwrt 23. To 25. I dont migrated the config. So i start from Scratch.

Unfortunately iam not getting wan/pppoe working.

I have a vigor as Briged DSL Modem (which Inserts vlan 7 Tag) connected tinthe wan Port of my r7800. In Openwrt i have configured wan Interface as pppoe with my Login and Password.

In the old Openwrt Version i had eth0.2 ... Now iam using wan.

Iam always getting Time Out waiting pad0 packets.

Could this also bei a Problem in Vodafone/Telekom Side ? Perhaps they blocked my Port because of the new mac or sth Like this?

Thanks for Help

PS - when inlogin to vigor insee that the VDSL Line is in sync

Have you tried to power down your modem and your router, wait a few minutes , power up your modem and then after a few more minutes power up your router?

Yes. I switched of vigor and Router ... Wait for 30 minutes and switched in again. DSL Line comes up sync is stable.

But i geht Time Out pad0 / Connection attemot failden in Openwrt Side .

Is there a Special config for the new Switch dsa architecture ?

It's different from the swconfig way.
How about you share your /etc/config/network?
Don't forget to redact at least your credentials.

Try changing option device to wan.2
After this restart the router.
