Okay, I'll just use wired devices from now on then.
For real security, you basically have to. Even without this, jammers can be used by thieves to disable wireless cameras and security systems.
WPA2 (and I believe 3 as well) are notoriously easy to crack the passwords to. Wired is truly best for security, and for wireless WPA Enterprise can help with securing the network
I don’t believe this is the case. 3 is fairly robust, and 2 is still just brute forcing, though rapidly on a local CPU. The one that’s trivial is trivial to crack is WEP.
WPA2 is pretty trivial too. Not as easy as WEP since you do have to locally brute-force the PSK (password), but that's pretty quick on modern systems. We had multiple assignments when I was in college that had cracking a WPA2 password as a step (in the interest of time, the instructor used passwords from the RockYou list but still)
Yeah, if you’re using common words or variants thereof, you’re gonna have a bad time. But a 128 character string of random characters is going to be functionally safe from such an attack, for now.
And you'll go crazy every time you try to add a device that doesn't support QR code scanning.
Just use multiple dictionary words with a symbol or two thrown in. Or go all out and set up 802.1x with client certificates and save the PSKs for a firewalled segment of less important crap.
Although it's worth mentioning that wireless security means nothing to jamming. Jamming is RF, it's destroying layer 1 before WPA matters.
