I am trying to connect Connecting AC1300 Deco M5 to a BTOpenreach Modem.
but the Deco M5 unit is not connecting to the internet.
it detects that the modem uses PPPoe and asks for a username and password.
I have looked this up on the BT forum and apparently the username is firstname.lastname@example.org and the password is BT.
I have used these but when the setup app starts testing the internet connection, the light on the Deco unit turns red and the app says that the Username and password are wrong.
what am I doing wrong?
Solved! Go to Solution.
I have not had a response from this forum but I have resolved the issue...kind of.
The modem does not have a dynamic IP (it has PPPone) so it needs a username and password. None of the Un & Pw combinations that I was advised to use or found online worked.
In the end I plugged in my old plusnet router, turned off the WiFi and plugged the deco into that. A solution of sorts.
By default, the Openreach modem should be in bridge mode, the PPPoE session is handled by the router using the details in your original post. I suspect the modem had been misconfigured in router mode.
Try a factory reset of the modem.
