Can QoS be made to use 100% bandwidth if nothing else is using it? (shibby1.28)

    Been using my Asus RT-N16 for a couple of days after immediately flashing with shibby Version 1.28.

    Been wanting a router with QoS where you can specify download/upload limits on each port.

    However I was not expecting the maximum percentage (e.g. I may set 50% for HTTP traffic) to be a hard limit?

    Is it possible for the router to decide that there is nothing else being used on the other ports and temporarily give HTTP traffic 100% until it detects other traffic and then lower it back down again?

    Interesting topic, I would like this feature too - I have 3computers at home, I divided bandwidth between them in 1:1:1... but if 2computers are not connected to the site I want to get full speed of my computers which is online and connected to my site...

    Is that possible?

    Maybe I'm not understanding your problem but why would you want QoS without hard limits? Apart from that bandwidth that isn't used can be used by other classes if those classes are allowed to use more bandwidth than they already utilize.

    The left value is the gauranteed bandwidth, that's what each class can always utilize. The sum of all left values must not exceed 100%.

    The right value is the hard limit. If you want one class to get all the available bandwidth give the highest class 100% and adjust your filters accordingly. I strongly advise against giving one class 100% in the left value, except if you disable all other classes.

    Last but not least: read the tutorial http://linksysinfo.org/index.php?threads/using-qos-tutorial-and-discussion.28349/

    If you still run into problems or want to do something special/exotic, ask again, with more details describing what you want to achieve.

    I personally disable qos every day at 0:30 with the command:

    to allow my downloads & backup over VPN to use the full bandwidth available (as everybody is asleep anyway). This way QoS comes back in place at 9am.

    I have thought a lot about this topic in the past and technically I think you can use netcat to trigger the qos start/stop, or use something more complex as per below (nvram show | grep qos to see hat I'm talking about) e.g. to set outbound rates in percentage:

    If you go this way remember that changing NVRAM value from the shell DOES NOT change the values on the GUI.

    If you ask me: keep it simple and leave qos where it is.

    I believe that is what QoS should be for... to give QoS Assurance & priority to certain type of TRAFFIC. When that TRAFFIC is not there, it should allows that bandwidth to be used.
