Same problem as ##584

With itlwm v1.2 it get the rigth dhcp ip and wifi work but keeps connecting/disconnecting in some seconds.
With v1.3 or 2.0 randomly connect and all work fine until restart.

@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.

williambj1 · 2021-09-23T06:47:25Z

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

SnowWarri0r · 2021-09-23T09:46:19Z

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.

MaxSYC · 2021-09-23T13:56:36Z

@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 · 2021-09-23T16:36:09Z

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

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

zxystd · 2021-09-26T01:20:56Z

@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?

@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.

pigworlds · 2021-09-26T04:50:45Z

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 · 2021-09-27T09:04:28Z

@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.

@zxystd @williambj1 @pigworlds

Ok i figured where the problem start
( I already tested before with v1.3.0 and v2.0 setting the router at 20mhz and no force 40mhz but dhcp problem is still present )

Compiled v1.3.0 at Merge branch 'ampdu_impl' into abc - f7fd518

Result: is fully working wifi at 20mhz? ( no connect/disconnect like in v1.2.0 ). Max download speed is 55 Mbps ( In windows i get about 70mbps). I cant get more than 70-75 on any device so i think this is the 2.4ghz wifi limit for the router

Compiled v1.3.0 at support 40mhz - e4051fb
Result: cant connect and keep asking for wifi password
Compiled v1.3.0 at enable Tx agg for iwi again. - 7a0e773
Result: cant connect and keep asking for wifi password
Compiled v1.3.0 at use correct rate for non-data frames - a6af0af
Result: it connects but got the same problem of dhcp auto assigned ip
Compiled v1.3.0 at set iwm rate table 40mhz flag, now the tx speed is normal. - 9d7ba10
Result: it connects but got the same problem of dhcp auto assigned ip
Compiled v1.3.0 at fix bug - 9b8cbb7
Result: it connects but got the same problem of dhcp auto assigned ip

williambj1 · 2021-10-05T09:20:53Z

@elsacorv When the advanced menu from airportd (hold ALT while clicking the menu icon) is opened, does it say it's connected with channel 11, 40MHz?

I'm not an expert but I noticed that ht_capab has [HT40-]. Is it possible to enable the AP manually by passing a config to hostapd from the command line while setting ht_capab to [HT40+] and removing the hardcoded channel number on your setup? If so, could you try removing [TX-STBC][RX-STBC1] as well?

Tried with Openwrt 21.02.0 default config - itlwm stable 2.0 and no success
Tried with channel 6 which is HT40+ and no success

Last working 100% with compiled v1.3.0 at Merge branch 'ampdu_impl' into abc - f7fd518

zvova7890 · 2021-12-17T04:46:07Z

Same problem on ax200. I'm installed v1.2.0 seems last working version. OpenWRT 21.02.0 with 40mhz force

elsacorv · 2022-01-23T06:57:53Z

Yep, but you can try v1.3.0 compiled at f7fd518.
I had wifi problems and low speed with 1.2.0 and 1.3.0 was not working fine

Check on my user releases
https://github.com/elsacorv/itlwm/releases

zvova7890 · 2022-01-25T19:18:14Z

I'm checked yours 1.3.0 version and wifi is work! But no speed different between 1.2 and 1.3 in my case. 5Ghz wifi shows around 30mbit with iperf3. I'm using hackintosh in very special cases, so that speed is enought for me

zxystd · 2022-01-27T06:55:21Z

@elsacorv @zvova7890 Hi! Have you tried v2.1.0 or v2.2.0-alpha version with boot-args -noht40? You are using 2.4ghz wifi right?

williambj1 · 2022-03-03T06:40:27Z

Closed due to no further response.

zvova7890 · 2022-04-05T18:01:24Z

Hi! I have checked v2.1.0 - 2.4 and 5 doesn't work. v2.2.0-alpha - seems work without any tweak, after install both 2.4 and 5 GHz wifi working pretty good, connection speed is much higher than elsacorv user build. So I think this is fixed in alpha. Thanks!

zxystd · 2022-04-05T23:18:40Z

Yes, there must have something error inside thd -48 firmwares, thank you for the testing.
