pfSense speeds suddenly slow

@leonroy There is so much information lagging here that one cant comprehend.....
Running IDS/IPS and do you route IPv6?
-
thanks for the reply, no I don't route IPv6.
Also no IDS/IPS - not running Snort or Suricata.
Just running the following services:

a little bit more info around packet loss both externally:
and from within the network:

Does your ISP router also use the external modem (MT992?) or is it built in?
That sort of speed throttle and packet loss I'd be looking for a bad cable or port too. I assume that turned out not to be the issue?

SteveYep, using the MT992 external modem provided by Zen Internet.
So I suspected the cable since after swapping it the speeds improved but they fell again shortly after and yo-yo around like this:
Speedtest Bandwidth:
Speedtest Latency/Jitter:
Swapping routers from pfSense to the ISP provided one (same MT992 modem though) totally resolved the issue.
It might well be the NIC since the Supermicro A1SRi-2758F motherboard in my pfSense box is over 5 years old now.
In any case, I've purchased a SG-1100 to see if it resolves the issue.

Hmm, that is significant variation!
Can you swap NICs in pfSense to test a different one as WAN?
I have a similar setup but unfortunately I'm towards the longest cable run for g.fast so I never see more than ~140Mbps

Hah, yeah easy to get spoilt vs what some other people get from their exchange. My understanding of G.Fast though is that it can be quite unreliable if the distance from your cabinet is more than 250m...do you experience reliable, consistent performance at 140 down and whatever your upload speed is @stephenw10 ?
Regarding swapping ports - yep did that last night and also swapped over to the ISP provided router a Fritzbox 7530.
Here I'm running Speedtest every 5 mins and log the result in Zabbix (network monitoring tool). Interesting variation between the two routers - the swap occurred 23:20 ish on 8th Feb and then swapped back the next morning at 10:15 ish:
BQM - pfSense on left - Fritzbox on right:
Speedtest - Bandwidth:
Speedtest - Jitter/Latency:
You can see the status with the pfSense box on the left and the ISP provided Fritzbox 7530 on the right in BQM.
Fritzbox is definitely more consistent in performance but it's still quite up and down unless that's normal...

I've never generated data like that but I pretty always see 140Mbps when I run a test against, for example, fast.com. I've never seen it below 130Mbps.
