What would cause a high latency ping to my local pfsense gateway?

Netgate XG-7100
v2.4.4-RELEASE-p3 (amd64)
Unifi APs/switches

I've been running a ping test on loop. I'm pinging a few IPs. One of them is simply the gateway IP of the pfsense network I'm on.

I'm on a laptop, connected to a Unifi AP, which traverses 3 Unifi switches over fiber, into the Netgate.

The pfsense network I'm on (via wifi/VLAn connectivity) is 10.102.20.2/23
So I'm pinging 10.102.20.2 and every once in a while, maybe every 50 pings about every 5 seconds, it goes from an average of 4ms to ≈ 100 ms.

I've closed pretty much everything on my computer and just have the ping application running.
Any ideas what might be causing this?

Try a wired connection, its the same?
If not its your WiFi.

You see anything logged in pfSense?

Spikes in the CPU monitoring graphs?

Something jumping to the top of the table in top -aSH?

You should upgrade unless you have a really good reason to be on that relatively ancient version.

Resources appear to be fine not seeing process spikes or spikes on any graphs.
I am trying to tell it to update but seeing "Please wait while the update system initializes" status here for about 10 mins

I did update to next deprecated build so will try next update after that.
However in the meantime I do appear to have much lower latency wired into the switch.

However I ran a ping test to my local pfsense network gateway, and out of about 330 pings, there were 5 failed consecutive pings.

Any idea what could be causing a failed ping to a local gateway? I'm literally traversing 2 switches

If there's nothing in the logs then I'd run a packet capture to see if those ping are making it to pfSense at all and if it's responding.
No response to 5 pings it something significant though. An IP conflict maybe? Something ARPing with the same address could do that.
