Packet loss/high latency



  • I have Comcast business line 50/10 package. When i peak downstream at 54Mbps, my ping times to the gateway jump from 10ms to 50ms+ and I am seeing packet loss. Is this an issue on my ISP end or pfsense?

    Are you using the ISP supplied router or do you have your public IP on the pfSense WAN?
    If you go to Status: Interfaces: do you see errors?

  • I am using a personal owned router as the ISP router would not operate in a full bridged mode, instead it would NAT all my traffic. I switched to a Motorolla Surfboard 6121 so that I could achieve a true bridge. My public IP is assigned via DHCP to the WAN of my pfsense system which in bridge mode. I navigated to Status>Interfaces and under WAN I see In/out errors 261/0



  • Some more details from the WAN interface:

    In/out packets 153109587/103005275 (199.23 GB/10.73 GB)

    Hmm, not a significant number of errors then. I would suggest it's problem at their end.
    Do you have access to the modem web interface? You could try pinging that or checking its loading.

    Try changing your monitor IP to something other than the WAN gateway, say 8.8.8.8. The gateway router may be, justifiably, prioritising ping responses far below everything else.
