    I read the wiki page and am still a little confused... if I enable the check box in Qos "prioritize ICMP" do I have to do anything else (like create Rules etc) to make ICMP highest priority, or is just checking the box enough? I see ICMP is available in the protocol drop down.

    edit I think I answered my own question..... I checked the status and when pinging, it is still putting ICMp in the "default" class. So I make a custom rule for it to boost the priority.

    will see if this works :redface:

    Is this just a QOS test, or what will prioritizing ICMP give you?

    Reason is, I am having problems with latency to my first hop (DSL connection). It is normally 6-9 ms to my first hop, but past few weeks I am having an issue where this will jump up to 180-250ms. Sometimes due to network traffic it is hard to tell if upstream traffic is to blame, so I wanted to try to prio ICMP traffic to avoid this confusion.

    There is no reason to do that, I might give you lower values when using ping, but it won’t do any actual difference. Remember, ping is for finding problems like that so the cure is not to fix ping, you have to find the real source of the problem if you want real results.
