I guess it can be related how those drivers works: Intel dongle has the correct name (wlp6s0).

Hi, I'm not sure whether this bug is related to initscripts. It seems more like some driver issue as you mentioned.

@joy4eg , please why do you think that this is bug in initscripts?

@jamacku I'm not sure where is the right place to post this issue :) I found that device renamer lives here, and that's why opened the issue.

@joy4eg may I ask you what is actual issue?

To me It looks like you have dedicated wifi card and in same time external usb wifi connected to your pc. There for its normal in my opinion.

may I ask you what is actual issue?

The issue was when I plug-in my external (USB) WiFi dongle it gets name wlan0. Expected name: wlan<usb bus><usb dev>.

For instance, I have two different dongles: ALFA Network AWUS1900 (RTL8814AU) and wavlink AC600 (MT7610U). I have a PC (X570 aorus master) with rear usb port. When I plug-in the RTL8814AU device, it gets name wlp15s0f3u2 Then, when I plug-in the MT7610U device in the same port it gets name wlan0

Anyway, I did a few tests again and looks like the issue is gone. Thanks for the feedback!
