PPPoE attempts

Hello everyone! Due to poor ethernet connection router sometimes loses PPPoE session without sending PADT packet. Then it tries to reconnect to AC but login+pw is still taken by old session for 2-3 minutes. All this time router tries to reconnect 3-5 times in a second and overload by this attempts. Is it possible to change it from 3-5 times in a second to 1 attempt in 30 seconds?
