Hi All,

where i can find a list of all devices that currently supports 802.11w?

What I would like to know is if Liknsys WRT3200ACM can support it.

For now there is only few of them specified in LUCI:

As of Jan 2019 there were 4 chipset supporting 802.11w.

Are you saying that all chipsets are now supporting 802.11w?

:confused:

No - I directed you to the table of hardware. I guess you cannot see the 4 links above to the 4 chipsets listed?

I'll post them again:

Please observe the 4 chip names in the link. If you didn't open the links, tehy list all devices with the given chipset.

Actually the situation has improved in recent months (in master), due to more emphasis being placed on wpa3 compatibility (which mandates 802.11w). As a result a number of drivers (e.g. ath5k and the rt2xx0 driver family) that don't really support it, have been 'fixed' to fall back to the nl80211 software implementations of the wireless stack - this usually comes with a hefty performance penalty (as hardware acceleration needs to be disabled), but at least it works.

Of those drivers mentioned above, mwlwifi has difficulties with "optional" 802.11w (and thus also with WPA2/WPA3 mixed mode).

As that mwlwifi driver is abandonware with a closed-source firmware blob, there is not much hope that the 802.11w support will get fixed.

Barely. The "mandatory" may work, but with "optional" the connectivity breaks once there are both devices using w and devices without w...
