Hi William,

I checked internally, and there should not be any issues with v0.9.3 of the nRF7002 EK that should be causing this.

Can you provide some information about the "Nordicsh" router? What model is it?

[quote user="William.wei"]i have tried 5340dk + 7002ek, with router"Nordicsh", it works.[/quote]

Have you tried building with CMSE disabled (nrf5340dk_nrf5340_cpuapp) as well, or only with nrf5340dk_nrf5340_cpuapp_ns? If you have not tried without CMSE yet, please do so.

Best regards,
Marte

Hi William,

Can you provide some information about the router that it does not work with?
Do you have a nRF5340 DK you can test the nRF7002 EK with?

[quote user="William.wei"]and i am suspect 7002ek version, my 7002ek version is 0.9.3&& 2023.20, is thre any problem with this version? [/quote]

I am not sure if this is an issue, but I will investigate it and get back to you.

Best regards,
Marte

Hi Marte,

it confuse me as i can run it correctly when building as 7002dk, however the same project is not working when building as 52840dk+7002ek.

i am quite sure the password is correct and i can see them same in those two logs.

however, i tried different routers:

CONFIG_WIFI_CREDENTIALS_STATIC_SSID="Nordic_ASUS_5G"

CONFIG_WIFI_CREDENTIALS_STATIC_SSID="HONOR_50_Pro"

52840 can work normally with both router except:"Nordicsh" in my prj.conf in the attachment

and i am suspect 7002ek version, my 7002ek version is 0.9.3&& 2023.20, is thre any problem with this version?

Regards,

William.

Hi William,

I did some tests on my side and I was able to reproduce the issue when the network password was incorrect. Can you please verify that CONFIG_WIFI_CREDENTIALS_STATIC_PASSWORD is correct?

When the password was correct, I could successfully connect to the network with the nRF52840 DK just as with the nRF7002 DK.

Best regards,
Marte

Hi William,

Based on the logs, the nRF52840 DK does not receive the AP's third message (EAPOL-Key 3) in the 4-way handshake. Instead, the AP resends the first message (EAPOL-Key 1). It could be that the Message Integrity Check (MIC) value that the nRF52840 DK sends in EAPOL-Key 2 is incorrect, causing the AP to restart the handshake. I do not see why this should be an issue only with the nRF52840 DK, but I will look into it and get back to you.

Best regards,
Marte
