@elsacorv Which OpenWRT version are you using now? And can you share you wireless security configuration screenshot. I'm curious if this bug is triggered by how we set that. Currently I still can reproduce this problem if I don't use my setting below

By the way, I'm using OpenWRT v21.02.0 and this is found when testing #676.

Does WiFi work as expected for you when 11w is disabled? Would you mind sharing the testing results from #676 as well? Thanks.

I have this problem too.And when I use WPA-PSK,it will be OK for me.But it will disconnect and connect over and over again until it gets DHCP IP.

Environment

• Kext Version: 2.0 Stable
• WiFi Card Model: Wifi 6 AX201
• macOS Version:11.2.1 Big Sur

By the way,my Openwrt version is 19.07-SNAPSHOT r11314-b4a4d04b91.

I tried this configuration but it didn't work on my laptop.

@williambj1 Here is my Logs (if you still need it). I just following all setting mentioned in 676# and the result is as the same as this DHCP issue, get a self-assigned ip addr.
With latest alpha release and 11w disable, connection stability and speed is the same under Windows.

[elsacorv]

I tested 3 routers versions are:

• 19.07.7
• 19.07.3
• Lede 17.x

Tried WPA2-PSK and WPA-PSK.
Managment Frame protection is off.

Sometimes with v1.3 when i connect to android hotspot before where mac get ip 192.168.43.17x and after connect to openwrt router worked 2 or 3 times and wifi was 100%

Upgraded Openwrt to v21..02.0 but no success. ( Whats you router model? )
Can post your router /etc/config/dhcp?

Thanks

I'm using Mi R3G model(mt7621 SoC), but I don't think I have made any specific modification to my dhcp config(?) Hoping this can help you anyway.

@MaxSYC Hi, you mean you have seen problems when testing #676 with 11w enabled? CC @pigworlds

[zxystd]

@elsacorv with the log, I can see the WiFi signal is weak and trigger the roam scan, can you move closely to the router and test again?

@zxystd
There is 0% chance of be for signal strenght ( is very good signal rssi 34@39 ) but i tested anyway at 3 meters and same result.
With v1.2 it gets correct dhcp ip in 3 or 4 seconds ( and internet work until 10 or 15 seconds when i do adsl speed test and it start disconect and connect and work for some seconds and repeat).

So i think the problem is some commit v1.2 -> v1.3 related to auth & dhcp, maybe some of these:

• Only retry when current state is AUTH. ASSOCIATION state should be an…
• reject invalid status.
• Give more times to try associate to a BSS.

Maybe can you compile v1.3 without these for test? ( i dunno really if some other commit is related just giving out ideas)

This is the router log with v1.2 ( With v1.3 or newer always end at pairwise key handshake completed (RSN) and never do DHCPDISCOVER or DHCPREQUEST )

@MaxSYC
Thanks for your dhcp config.
I tested some params in my 19.07.7 because i think maybe is the " default config " of v21.02.0 who is doing the magic but no success.
Tomorrow i will upgrade again to v21.02.0 but without saving my current config so i can test with default config.

By the way, I'm using OpenWRT v21.02.0 and this is found when testing #676.

@MaxSYC Hi, you mean you have seen problems when testing #676 with 11w enabled? CC @pigworlds

@MaxSYC I saw your log indicate your card is ax200 using iwx. Currently the 11w support in #676 doesn't cover any gen2/gen3 card yet. I just updated the description to call it out. What the behavior your see is expected when enable 802.11w in OpenWrt.

@zxystd I don't have any gen2/gen3 card in my hand to test. Do you mind if I enable 11w support for iwx using mixed hw/sw crypto, similar to iwm in #676?

[zxystd]

@pigworlds

@zxystd I don't have any gen2/gen3 card in my hand to test.

Sorry I don't notice it is a iwx device.

Do you mind if I enable 11w support for iwx using mixed hw/sw crypto, similar to iwm in #676?

Of course you can do that, and post it here or #676 then somebody who can download to test.

@elsacorv Hi! Would you mind sharing your hostapd config file? Thanks!
