I have a personal router connected to one of the port on the sagemcom. (using my b1xxxx code and a pppoe style connexion on the personal router)
It was working fine until last night. now, it stopped working. If i remove the sagemcom b1 user, my personnal router can connect.
If I put it back, my router gets deconnected and the sagemcom reconnect.
I called tech support... the guy is clueless and more, he told me that there was no new firmware updates (that not what ppl in the forum are saying)
Bottom line, the multiple PPPoE was working until lately..
