802.11r not working properly

Hi, I've just written this post on reddit:

from wpa_cli I can see that all APs support wpa2 FT, but when the roaming happens, these are the logs from the AP:

As you can see, every time it uses WPA 4way handshake instead of FT.

Ft has to be supported by the client. Are you 100% certain client supports?

I’m not 100% sure, because I cannot find more infos about how to check if client support it, but as of now I tried also with huawei honor 9, that is a fairly recent mobile phone, and also an iphone 7, and no one uses FT

ok, reconfiguring everything, seems that only the iphone uses FT and all the other clients I have in my house has android with 802.11r disabled.

Now I'm trying on a different device, a netgear R8000: when I enable 802.11r, the client can see the connection but cannot connect to the station. The configuration is similar to the one reported on the reddit topic, Is there something wrong with broadcom boards + 802.11r?

you might well need the full version of dnsmasq to get FT working.

It's hard to get info on 802.11r support, some Samsung phones advertise it in the small print, but I think still most android phones don't support it even brand new ones.

Broadcom wifi drivers are pretty limited.
It maybe does not support 802.11r at all.

why would this feature dnsmasq-related?

Sorry I meant hostapd I think there is multiple versions available on lede?

as of now I already compiled with wpad full. Do I need to recompile removing wpad and install hostapd full instead?

I really can't say for sure, but that's what I suspect is that you need hostapd full for 802.11r. I tried to set this up too, and it shows as FT supported on Wifi Analyzer, but my older moto g3 doesn't support it so I don't get any benefit... eventually when I upgrade my phone I'm hoping to finally have decent fast roaming, particularly for VOIP it's no good the 1/2 second to 1 second drop-outs during handoff.

EDIT: and yes, I installed hostapd full and I think that means I needed wpa_supplicant and uninstall wpad

unfortunately, with android there are not too many devices that support 802.11r. I've just bought a huawei honor 9, and it does not support it. The only mobile devices that supports r/k/v for sure are the apple ones....

same problem, with 802.11r, hostapd full, my r8000 doesn't give access to any device. Also, as you can see here

it declare WPA2-PSK-CCMP instead of WPA2-PSK+FT/PSK-CCMP
