[Emmanuel-Messulam]

I have a wn723n; and I have installed the driver on a tegra tx2 and can't get the interface to show.

But lsusb detects the device:

Any help?

Hi!
Please paste info:
For DKMS installation - dkms status lsmod | grep 8188.
For non-DKMS installation - ls -l /lib/modules/$(uname -r)/kernel/drivers/net/wireless/ lsmod | grep 8188.
Before and after connect adapter.

If you use dkms... be sure to validate in the Makefile that the correct architecture is selected as well. If it is not matched correctly odd issues can result, even if the compile is successful under dkms build.

Hello sir !
Which information paste ?

[Jibun-no-Kage]

Not sure what you are asking?

[ankit7297]

After install without dkms wifi interface not show .

[ivanovborislav]

ls -l /lib/modules/$(uname -r)/kernel/drivers/net/wireless/
and
lsmod | grep 8188
and paste result.
