Re: wlan0 Interface doesn't support scanning.

Please post the commands you used to determine that wlan0 doesn't support scanning, along with any additional output those commands output.

Also, please tell us what hardware you're using (is this an integrated network device, or a USB dongle, etc., what is the make and model?)

Re: wlan0 Interface doesn't support scanning.

There is no wlan0 interface to try to scan on - your problem  is much earlier than scanning, you have to configure your driver.

What is the wireless card?  Post the output of

lspci -vnn | grep -i net

Re: wlan0 Interface doesn't support scanning.

I think that my wifi device not worked in kali linux (and in other versions such as ubuntu).
Should I install things for enable wifi service?
Also:

# iw dev
nl80211 not found.

Re: wlan0 Interface doesn't support scanning.

It looks like support for that card is not complete (one site reports it is a WIP) but a github page seems to suggest it may be ready if you build it yourself:
https://github.com/kuba-moo/mt7630e

Otherwise, you'll likely need to use ndiswrapper.

Re: wlan0 Interface doesn't support scanning.

Trilby's research is pretty much in line with what I found.    I did see a couple posts where people decided to scrap that card and go with an Intel card.  It appears that Intel is supported by HP and there were no problems with the interface not being on a BIOS whitelist.  The parts had the same RF connector as well.  Cost ~ 25 US$.  YMMV.

Re: wlan0 Interface doesn't support scanning.

I am also facing the same issue but It's not Mediatek in my case
I have Gnome setup and I have tried setting up

nm-applet

using it https://unix.stackexchange.com/question … gnome-3-20
But I think that was useless because I tried

nmcli dev wifi list

and it was empty.

iwlist wlan0 scan

gave

wlan0     Interface doesn't support scanning.

Output of

lspci -vnn | grep -i net

01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL810xE PCI Express Fast Ethernet controller [10ec:8136] (rev 05)

Do experiment at-least.

Re: wlan0 Interface doesn't support scanning.

Also I have used Ubuntu before it and my wifi drivers were perfectly working there.

 $ nmcli radio wifi

enabled

Re: wlan0 Interface doesn't support scanning.

Yo, don't necrobump and certainly not off-topic. Thanks.

Your problem is that you've  a broadcom chip, https://wiki.archlinux.org/title/Broadcom_wireless
Figure what module is used on ubuntu (likely wl) and make sure to use that on arch as well.

If you've further issues, please open a new thread, detailing your setup.

Re: wlan0 Interface doesn't support scanning.

Closing this old thread, please pay attention to the dates and don't bump something that's six years old.
