can't connect through networkmanager with DSL 9.10

on 9.04 have no problem with this, but this new release couldn't find a way to do it.

i configure network manager with the user & password than my isp gave me. when i select from the drop down list, it tries to connect, but fails and then switch to the last working connection (wifi). i disabled wifi, and the problem persist.

even more, after i add the DSL connection, i thought there were a character missing on the password, so when i try to edit that DSL connection it warms me about authenticate, but i can't and i'm really sure about the admin user password (after that i create another DSL connection and use the same admin password). so there 2 problems here: can't connect and edit DSL properties authentication.

also try to use pppoeconf with no luck either.

any ideas? is a bug?
