Data traffic issue in imx8mp wlan0 interface

[krsuresh]

Hi Team,

There is a problem with data traffic from the client to AP mode. The same is working in promiscuous mode and AP mode to client working fine.
Is there I am missing configuration in yocto kernel. It would be greatly appreciated if you could assist me.

In order to configure wifi AP mode with virtual interface, doing the following procedure.

Virtual interface creation
iw phy0 interface add ap0 type __ap

ap0 ip address : 192.168.4.1

dhcp configuration in dnsmasq.conf
interface=ap0
dhcp-range=192.168.4.2,192.168.4.20,255.255.255.0,24h

systemctl restart dnsmasq

hostapd(AP mode) configuration in hostapd.conf
interface=ap0
ssid=Test
channel=1

systemctl restart hostapd

Firewall details
imx8mpsolidrun iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

Thanks,

Hi, @krsuresh 

To save your precious time, I strongly suggest you to ask Infineon Wi-Fi technical support to give you better support on your issue because you are using Infineon Wi-Fi chipset. I believe they could give you correct direction to locate the root cause and correct solutions. 

Best regards,

Christine.

Hi, @krsuresh 

Could you please help to provide your failed dmesg logs (please use drvdbg=0x20037 parameter when you insmod Wi-Fi driver to enable debug logs) ?

And provide your host Linux kernel version, Wi-Fi driver/FW  version to me?

I can help you to check your failed logs and also if you provide me your basic Linux kernel version, Wi-Fi driver/FW version, I can test on my local side. Then may output some guide to you.

Best regards,

Christine.

Hi, @krsuresh 

Please also tell me your Wi-Fi chipset model because I didn't see any information about your Wi-Fi chipset.

Is it NXP Wi-Fi Chipset? or Are you using your private third party Wi-Fi chipset through external interface?

Best regards,

Christine.
