Wi-Fi Protected Access 3 (WPA3) support

I bought a Raspberry Pi Zero 2 W and apparently it does not support my home wifi which uses WPA3.

I excepted that to be the case, since on Debian usually works just fine, and this device is a new release.

It should be at last officialy stated somewhere that is not supported. I basically bought something I can't use.

Notice that WPA3 is not anymore a theory, many commercial routers now ship with it in mixed mode or add that through firmware update.

Side note: actually run just fine on common operating systems from Windows to Android, including Linux if you have no firmware issues.

Which AP is this that doesn't support WPA2? It seems a bit premature.

Is wpa3 possible with debian bullseye with Pi zero w2?

[pelwell]

No Raspberry Pi currently supports WPA3.

[kroon040]

So the RPI 3 and 4 supports WPA3 and the RPI Zero 2 not?

"No Raspberry Pi supports WPA3"

As in, none of the Raspberry Pi's with wireless support WPA3.

@JamesH65 is this because wpa_supplicant version which supports WPA3 is 2:2.9-4, but the wpa_supplicant version available on Raspberry Pi 10.11 is 2.8-devel. Or will it require a kernel driver update from Broadcom? Or a new Wifi chipset?

[JamesH65]

I believe it will need at minimum new firmware, quite possibly a new chip.

According to https://forum.openwrt.org/t/wpa3-support-in-openwrt/10554/144 there is no special hardware support needed for WPA3 with OpenWRT devices.
So when you can create an access point with WPA3 encryption in software, than it should also be possible to implement the client solely in software.
Would also be very glad when Raspberry PI Zero W and Zero 2W support WPA3.

Connecting to a WPA3-Personal network works fine for me with a Pi 3 Model B when I use iwd. I recently bought a Pi Zero 2 W thinking it would behave similarly since supposedly the wifi hardware is almost identical, but unfortunately that's not the case. Same kernel/driver, same network, but it fails to connect.

iw reports support for the SAE_OFFLOAD extended feature among other things on the 3b, not on the 02w though. So that's one obvious difference. Looking at the brcmfmac driver, it seems that that feature flag gets set if the firmware claims support.

The 02w wifi firmware then looks rather "beta" to me, going by the version string:

BCM43430/2 wl0: Oct  9 2020 14:44:32 version 9.88.4.65 (test) (f149b32@shgit)  (r679549) FWID 01-f40f3270

I suppose it's incomplete? Are there any plans to release an updated firmware in the foreseeable future?

Why can't the raspberry pi broadcom wifi chips support WPA3 ?!?
I Tried many wifi dongles from cheapest realtek to atheros and such with wpa_supplicant 2.9+ they all work with WPA3, but broadcom raspberry pi's dont. I hope the new raspberry pi's comming will dump broadcom for something better....

[somerando905]

Are there any plans to release an updated firmware in the foreseeable future?

I take the lack of a response to mean "no."

That's too bad. But I noticed there are commits in the firmware repo referencing a new Zero 2 W revision with a different wifi chipset. Hope you get those wifi issues sorted out, it's a nice device otherwise. Cheers

I'm also longing for my Raspi Zero 2 W to support WPA3. I thought that's a matter of course these days.

No issue on my end:

/etc/wpa_supplicant/wpa_supplicant.conf:

update_config=1

network={
 ssid="ssid"
 key_mgmt=WPA-PSK-SHA256
 psk=psk
 ieee80211w=2
}
