Hi Caste,

Hi Castle,

It appears only your TP-WN822n adapter is being loaded as 8192eu in Raspbian. I’am unable to replicate this with my Edimax: [https://github.com/Fourdee/DietPi/issues/564#issuecomment-256379072](https://github.com/Fourdee/DietPi/issues/564#issuecomment-256379072)

Could you please confirm and paste results of the active module on your Raspbian installation:

```nohighlight
lsusb
lsmod

```

The funny thing is, the mac address also changes after the first reboot. before the first Dietpi reboot it is the same as under Raspbian.

The results as per your question:

I just gave it another try with the latest release (v136) and after the first reboot the mac address does not change!!!

WiFi happily running @300Mbit.

Don’t know if it was something with the latest release but thx!!
