Hello,

Which model is it?

Are you getting this output when you plug it in or are you executing commands before this?

Please attach a full log from power on.

Hi,

The exact model of the wifi dongle is : Edimax EW-7811UN

The error comes when I plug the stick to the card.

The exact message when plug it is :

Hi,

Have you got some news about this topic??

Thank you.

Fabrice,

I took a look at the driver docs for that adapter and it is stated that the driver package is supported under 2.6.18 ~ 2.6.33. You may want to test this adapter in one of our older 1.0 BSPs which use the 2.6.32 kernel [1] to see that the driver works and then update it for the newer kernel. FYI on the forums we do not support our older BSPs.

Hi,

I've solved my problem putting the right firmware.

But, I've got a new once : while plug and unplug my USB wifi stick, all is right, but when I reboot with the USB stick plugged it is no longer detected. Wlan1 is not available.

Is there something to do?

Thanks

Fabrice,

Have you tried testing the USB WIFI stick in both the USBH and USB OTG ports? If so, are you having the same issue in both ports? Are you using the latest available DM37x 2.4-2 BSP?
