I enabled WiFi logging by pressing Option ^ + WiFi icon in menu bar, and then went to check /var/log/wifi.log. The problem is that this file doesn’t seem to record what I want, so I’m wondering if there’s some other file I should be checking. Here’s the last couple lines of the file :

Right now it’s around 4PM, but the logs stop at around noon (and they start at around midnight), and I’m not getting what process is using the WiFi, which is what I’m trying to achieve.
I’m following this answer to try and find the problem that is causing my latency spikes, and is making parsec stutters when I’m using it (that’s irrelevant here, I’m just adding that for keyword information for anyone that might have some issues like me related to parsec). I’m also running ping in parallel, to pinpoint the time where the latency spikes happen.
I also tried solving this issue I had a couple months ago, and at the time I also got stuck at checking the logs. Back then the log file had only 1 or 2 lines (iirc) which were something like
“(something about my pc name and date) newsyslog[75627]: logfile turned over“. At the time I didn’t have WiFi logging enabled, so I had just enabled it. And so I gave up. Finally today I wanted to get back at this issue. WiFi logging has been active since then. So now I’m getting something more than 1 or 2 lines, but it’s still now what I’m looking for.
