In macOS there are also ping spikes when you open the WiFi menu bar [1]. This still happens in macOS Monterey. [1]: https://developer.apple.com/forums/thread/9

- walrus01 4y agoIf I had to guess it's because the system is temporarily pausing tdd wifi traffic while it scans the 2.4 and 5.x GHz bands to see what SSIDs are broadcasting. It is a bit of a trade off since if you want to see every possible available AP, even the shitty ones with signal levels at like -80, you can't be noisy on your own radio at the same time as you scan the band. Remember it's a half duplex medium. It does it even more if you hold down option and click the wifi menu bar, to get detailed signal strength/info on the AP you're presently connected to.
- nicoburns 4y agoThis seems more reasonable, given that: 1. I can't see how you'd enumerate wifi networks without degrading network performance. 2. The user has specifically initiated a wifi-related action. 3. There's not generally any need to use that menu unless the network is already not working.
