M2 Pro WiFi issues on Aruba Instant

Poisoning Internet performance:

By far the easiest way to cause poor performance, instability, overheating and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, or Virus scanners. or a VPN that you installed yourself.

The idea that a third party, with no special knowledge of the inner workings of MacOS, can somehow find a simple way to protect your computer — that is not already being done by MacOS itself — suggests that the MacOS developers are somehow "holding out on you". That is absurd.

You should remove any and all (other than Apple built-in) virus scanners, speeder uppers, optimizers, cleaners, App deleters or VPN packages you installed yourself, or anything of that ilk.

Once you have that out of the way, hold down the Option key, and click on the WiFi icon in the menubar.

You get a snapshot of current working parameters, like this older one. Screenshot, photograph with your phone, or transcribe, and post.

Also on that same Option-Wi-Fi menu is Wireless diagnotics, which is worth running to check for gross problems.
