      Are all of those whilst running a speedtest?

      You would expect to see higher ping times when the line is congested without any shaping to prevent that.

      Have you tried running a buffer-bloat test?

          Wen i setup the codel limiters like it is explained in the docs.
          and then test it with a speedtest the wan stopts working all together i can't reach anything anymore on the Internet.

            Do you see that same level of buffer-bloat with the laptop just connected to the modem?

            That's a pretty bad connection if so.

              yes it is the same and yes very bad connection. That is what i try to figure out what and were is the problem exactly so i can think of the fix but before i can fix something i need to know exactly were the problem is.

              First of all the internet connection is bad even with a system directly on the modem so that's what i know for sure.

              Wen i connect my pfSense netwerk to the modem the ping peaks are way higher en bufferbloat also more bad.

              Is there a relation between the two maybe?

              Another weird thing is wen i use the codel limiter the wan blocks all traffic maybe there is a relation with the bad ping or maybe i configured the floating rule wrong of created the limiters wrong. I read them multiple times over but all seems like it is in the docs.

                @gerard64 Check all cables and replace them.

                Report back.

                        Ah, then you will hit this: https://redmine.pfsense.org/issues/12954
                        It's fixed in 2.7 and 22.05. You could upgrade to either of those as a test.

                        With a link exhibiting buffer-bloat that badly you probably need shaping of some sort.
                        You could try using an ALTQ shaper instead.
