WAN Packet Loss raises to above 40% when large file download has started

PzrrL

I am trying the pfSense out for few days already, and I am playing with the traffic shaper now. This situation actually happens in both enabled and disabled traffic shaping. When large file download from Google Drive or Mega.nz has started, the Gateway status becomes offline, and the loss % is very high to above 40 or 50%. Besides, people from Discord is saying that my voice is very laggy while I was downloading. Once the download has finished, the loss returns to 2-5%. Anyone could please advise? Thanks!

and has the log:

Does it happen if you plug directly into your ISP's router? Did you try a different patch cable? What kind of network interface in the pfSense?

@teamits
pfSense 2.4.5-RELEASE, a VM running on UnRAID.
Passthrough an NIC (INTEL I350-T4v2)
My Setup: Modem -> pfSense -> Switch -> Other devices

My previous setup is using a Netgear R6900 as main router and DHCP.
When I return to my previous setup (without pfSense), the Google Drive download can go almost full speed with little flutuation (it was flutuating more when using pfSense), and without any packet lost in Discord (i can see it through Discord there is stats). Plus i am still able to do other works like browsing the Internet while downloading.

I am not using any patch panel or server cabinet, just running some cables around my home.

What does http://www.dslreports.com/speedtest tell you ?

@Gertjan With my previous setup (just the R6900 as main router), the result is here:

With pfSense (and traffic shaper[Dedicated Links - traffic_shaper_wizard_dedicated.xml]), the result as follows:

Without traffic shaper:

when you use shaping rules your traffic really goes down to 1 Mbytes / sec ?
Seems your shaper rules aren't set up quiet well.

Normally, your up/download speed shouldn't change, only the F grade - which means huge congestion, most probably the uplink, will mess up your connection. Which is "normal" these days, thus the usage of the traffic shaper.

edit : see the big "Playing with fq_codel in 2.4" - more then 900 posts - thread, loo at the end and set up your (floating) firewall rules. You should maintain your connection, and pass "A" easily.

@Gertjan Thanks for your reply. But the point is, comparing the result from R6900 and pfsense, the pfsense result (with or without traffic shaper is still not stable at all). I can go full speed and being stable in other tasks (such as Discord, watching YouTube) when using R6900, but I cannot with pfSense. The setup with pfSense basically paralyze my whole networking when doing some download work (eg from Google Drive). I am aware of the traffic shaper might not setup properly, but even without it, it can't meet up to the performance by R6900.

Gertjan

When you use the "R6900", you don't use pfSense ? And the other way around ?
hat's in front of the R6900 ? How do you connect to the Internet ?

PzrrL

@Gertjan Yes, the R6900 is from Netgear, and with ASUS-merlin firmware(not pfSense), but it is working great.
