I have exactly same issue, were you able to resolve the problem and what was the fix?Thanks for the reply. is there any way to save those 13 to 15% bandwidth?PPPoE overhead takes about 13 to 15% of your overall bandwidth. So you are well within the expected range.
Thanks a lot, will try to see how this plays out with download/upload limitI did a script a while ago to set speed limits per user accounts based on the plan price they were on, perhaps you can modify this to suit your needs.
