WAN speed has increased, pfSense throughput remains at old speed



  • My WAN speed has increased from 52 Mbit or so 72 Mbit. This has been confirmed by my ISP.

    I am using a Vigor 130 modem, its statistics:

    If I connect a laptop directly to the modem and configure the PPPoE settings, I get 70 Mb or so throughput.

    If I connect up the pfSense box, I get the old 50 Mb ish throughput. I've tested this using speedtest.py directly off the pfSense box. Does the same with various speedtest sites and usenet downloads.

    If did this before when I went from 40 Mb to 52 Mb, countless reboots and nothing then I upgraded the version, after the reboot it went up to the correct speed.

    So I thought I'd update it to the 2.4 RC, but it remains at 50 Mb.

    I've disabled snort. I don't have anything else running that would affect the speed, such as shaping etc.

    It's an SG-2220 so should be more than capable enough of 70 Mb.

    Any ideas please?



  • Well, I thought I'd try another reboot, and voila, it's now at around 70 Mbit.

    Can anyone shed some light on this behavior?



  • What's doing the PPPoE negotiation, the modem of pfSense? I have seen similar on my system. Re-initiating the PPPoE session corrects it.

    pfSense is.



  • There you go…  :)

    I suspect it's something to do with the ip profile in the DSLAM that get's updated when the session is re-started.
