nRF7002 DK Wifi

[PatN]

I've succesfully setup multiple nRF7002DK boards with an example app to connect to WiFi.

One out of the five boards the Wifi does not work. The interface stays down in Zephyr.

I've compared the switches on the boards and I did not identify differences. Identical binary file is used for all the boards.

What could be the reason of this?

Hi,

Do you try another USB cable or port on PC? Please ensure provide the correct voltage for the DK? 

Could you provide the log?

What NCS version are you using?

What is the DK version on the white sticker?

Could you take a snapshot on DK?

Regards,
Amanda H.

Thank you for the questions, see below the requested information.
I hope this helps to clarify the situation.

>Do you try another USB cable or port on PC? 
Same cable works with other boards. Different USB cable gives the same result.

>Please ensure provide the correct voltage for the DK?
It's powered via USB. Which voltage rail should I check?

>Could you provide the log?

uart:~$ net iface

Interface wlan0 (0x20009230) (WiFi) [1]
===============================
Interface is down.

uart:~$ net ping 8.8.8.8
PING 8.8.8.8
[00:05:13.821,624] <err> net_arp: Gateway not set for iface 0x20009230

[00:05:15.821,746] <err> net_arp: Gateway not set for iface 0x20009230

Above is understandable as the interface is not up/not working.

What do you exactly mean with taking a snapshot? A flash memory dump? A log trace?

Seems you are using NCS v2.7.0. If so, please try the latest version, v3.1.1. 

Are you using Wi-Fi: Shell sample? Could you try to connect to WIFI (wifi connect -s <SSID> -k <key_management> -p <passphrase>) before executing "net iface"? You can check the WiFi connection status by "wifi status" command. See the Testing STA mode flow.
