One other thing you might consider doing, now that we know that this is
a PPPoE connection: try running wireshark and capturing traffic from a
failed connection, a long delay, and then a successful one.
At a guess, PPPoE is the problem. I suspect the logs will show PADT
messages coming from your system (which may or may not be malformed),
along with either no response from the peer, or retransmitted messages
from the peer that are being ignored by your system.
My current hypothesis is that PPPoE is keeping the previous connection
up too long, and the peer doesn't like seeing you log in more than once
at a time.
I don't believe anything is going wrong with PPP itself.
