No, bandwidth isn't known to ppp. You can ignore this warning.
There is no connection between LQR and bandwidth.

Perhaps the peer does not accept LQR. Disable LQR.

Disable echo as well. These settings provide some monitoring
capabilities, but must be accepted by both peers. If for some
reason(probably misconfiguration) these are not accepted by
the other peer, things will not work...

But, try disabling only LQR at first.

It's not important. These IP addresses will be denied by the other
peer during IPCP. The peer will then provide you an IP address and
ppp will accept it.

Hope this helps
