Is wpa3 reccomended on a home network?

It seems i have the option but i have a vague memory of someone telling me not to bother with it unless i had a good reason

If your devices all support WPA3, go for it. There's a good chance older things won't.

- Most routers include backwards compatibility with WPA2 as a fallback, while newer devices will use WPA3. Should be relatively seamless

  The drawback is that evildoers can still attack the WPA2 handshakes and can force devices to downgrade, so you’re still getting effectively WPA2 level security until you actually turn off WPA2.
  
  But if it doesn’t cost you anything, you can just turn it on and make their life just s little bit harder.

  When I put my network on wpa3/2 mode my Xbox would not longer connect.

Admittedly it was a few years ago since I last tried, but even in WPA2 compatibility mode I had no end of trouble either getting things to join in the first place or weird stability issues afterwards.

Maybe things have improved now, but when 2 "just works" and is good enough for most use cases I've been reluctant to try 3 again.

Technically, the "best" option would be to VLAN the WiFi network separately from a wired network where all the important devices are connected.

But honestly, for normal people, that's over the top. Try WPA3 first and see if you have any devices that won't work over it. If you run into issues, swap over to WPA2. I generally say start stricter and loosen the metaphorical belt only as necessary.

WPA2 is just fine TBH. Use what works with all the devices you own heh heh

- I'm not so sure about this, KRACK was way back in '17

  It sorta depends on your physical security. If you live in a town, then sure, you can't know who's eavesdropping. But if you park in my yard, several hundred meters from the nearest public road, then I think we'd notice before you could do any damage.
