I have noticed that Ventura is less responsive in general than Monterey (which is less responsive than Big Sur, which is less responsive than High Sierra) on my MBP6,2, but raw Wi-Fi speed as measured by an online speedtest is unchanged.Has anyone noticed since going to Monterey or Ventura the WiFi seems slower than it used to be?
I pay for 100Mbps down/10Mbps up:
and as you can see (from these measurements in Ventura 13.3.1), my Wi-Fi is not slowing me down. It's as good as my wired Ethernet.
To be sure about whether "Wi-Fi seems slower," you might want to run speed tests in Big Sur, Monterey and Ventura to see if the issue you're observing is actually Wi-Fi (and not app performance).
