I'd like to ask for new alert box (yellow) that some SoCs will have abysmal WPA3 performance due to software implementation of 11w/pmf
Victim:
Documentation:
https://openwrt.org/docs/techref/hardware/soc/soc.mediatek
- These use the
rt2800socdriver. New features such as 802.11w (required for WPA3) are only supported in software, thus limiting your speed to ~14-18 Mbps.
(I can't help you with the wiki, but…) Does that really need a dedicated warning? Even without this specific WPA3 issue, rt2x00 is very limited for AP uses, so anyone picking this particular hardware vintage should be aware of its limits (the general performance is abysmal anyways).
10Mbps is barely usable nowadays, game stops when tv plays and vice versa. If user is told WPA2 then they stay there.
I think this would be useful.
I’ve tried to help many users diagnose slow wifi only to find it was SAE/WPA3 related slowdowns due to no hardware support.
Yes it is older devices, but there are still older ones with decent flash size around in use.
To my knowledge there is no flag you can detect in the system that it is supported or not. It might be available in the 80211 subsystem though.
Well, the dgradation in UX is on par with generic bcm experience.
Much of this referenced hardware is deprecated. Let me know specifically where you would like to add the language and I'd be happy to add it, but maybe not worth the effort of going through older abandoned doc pages for legacy hardware to update them all. Sometimes gotta let things go to move forward.
?rt2800soc? wifi chips are not capable of supporting WPA3 in hardware,
as a consequence WPA3 connections will consume disproportionate amount of
system CPU and provide sub-standard transfer speeds. WPA2 connections are
fully supported by hardware and reach expected transfer speeds.
On anything that is identified in mtk soc page:
MT7620 vs. RT5350 <<< these SoCs
These use the rt2800soc ~14-18 Mbps. <<< or this driver for soc-integrated 2.4GHz wifi.
@phinn to say something positive too even it is not good....
Ah I see, this is actually a huge list of devices and no easy way to update all their pages to put that warning in without manually going 1 by 1... this would take quite a while. I'll look at another way to do it.
8/64 minimum 
It is just 2 debices where rt2800soc driver is used and entered in toh
Thousands of devices came up when I clicked on those two chips in the ToH. No way to update them for a message like that I'm aware of. They are so old it hardly seems relevant tbh.
The actual driver (...soc) is preinstalled on too many dev(ces, even ones evidently carrying 2 other wifi chips.
Ok, for now I updated that Ralink SoC wiki you linked to recommend using WPA2 (and removed the outdated/dead links). If you want me to put it on any specific targets just link them here and I will (just not going to go through 100+ doc pages for obsolete chips adding it).
mt7620 Maximum is 8/64 , 10 years ago the driver was not recorded in TOH. the few survivors are identifiable using ethtool -i phy0-ap1 returning rt2800soc driver in use. Just use WPA2, no hope for WPA3 Hope I made it searchable.
