Manual Ping Limit QoS not working as expected
Posted: Mon May 04, 2020 7:09 am
My internet connection has recently changed from 3Mbps ADSL to 75Mbps fixed wireless NBN with more variable ping times. Therefore I am testing different settings with the ACC to try and get the most from the connection.
With Active Congestion Control turned on and Manual Ping Limit deactivated, I get the following results:
With a Manual Ping Limit of 60, the RTT time limit [36/40] changes to [97/178], so the minRTT increases by Manual Ping Limit and not sure what happens with the active mode:
And to confirm, when MINRTT activates, the minRTT includes the Manual Ping Limit:
According to the hidden help text, minRTT should not change like it does on my router, only the activeRTT should change equal to (auto minRTT + Manual Ping Limit):
I am using 1.12.0 on a Linksys WRT1900ACS.
With Active Congestion Control turned on and Manual Ping Limit deactivated, I get the following results:

I am wondering if this is a bug or if I have misunderstood something?Manual Ping Limit- Round trip ping times are compared against the ping limits. ACC controls the link limit to maintain ping times under the appropriate limit. By default Gargoyle attempts to automatically select appropriate target ping limits for you based on the link speeds you entered and the performance of your link it measures during initialization. You cannot change the target ping time for the minRTT mode but by entering a manual time you can control the target ping time of the active mode. The time you enter becomes the increase in the target ping time between minRTT and active mode. You can see the limits ACC is using in the [] brackets next to ping time limits field.
