Access point configuration problem on RPi3

Hi. I'm trying to establish AP on RPi3 with embedded wifi. So I was hoping for a quick start and tried a few tutorials:
1. https://elinux.org/RPI-Wireless-Hotspot
2. https://frillip.com/using-your-raspb...-with-hostapd/
But none of them worked out.

So I've tried manually start hostapd by running:

Code:

# hostapd /etc/hostapd/hostapd.conf Configuration file: /etc/hostapd/hostapd.conf wlan0: Could not connect to kernel driver Using interface wlan0 with hwaddr b8:20:eb:10:11:33 and ssid "my-wifi-ap" wlan0: interface state UNINITIALIZED->ENABLED wlan0: AP-ENABLED

So it is kinda working. At least I see my AP in airodump

Code:

B8:20:EB:10:11:33 -26 2 0 0 6 54e WPA2 CCMP PSK my-wifi-ap

If I try to connect to AP with my phone I see a message on RPi side:

Code:

wlan0: STA 1c:5c:f5:23:c4:11 IEEE 802.11: Could not add STA to kernel driver

There are other problems.
If I run:

Code:

# service hostapd start Failed to start hostapd.service: Unit hostapd.service is masked.

I've checked wifi interface with:

Code:

# iw list Supported interface modes: * IBSS * managed * AP * monitor * P2P-client * P2P-GO * P2P-device

so I see it can work as AP.

The idea is to establish a wifi connection and ssh to RPi.

Could anyone help with that? Thanks.

1. What adapter do you use?
2. Configuration of dhcp, dnsmasq are irrelevant in this case since it doesn't go any further than hostapd.
3. Have you looked up the error message "IEEE 802.11: Could not add STA to kernel driver"? What does it say about it?

Hi, thanks for reply.

1.

Code:

# lshw -C network *-network:1 DISABLED description: Wireless interface physical id: 3 logical name: wlan0 serial: b8:20:eb:10:11:33 capabilities: ethernet physical wireless configuration: broadcast=yes driver=brcmfmac driverversion=7.45.41.46 firmware=01-f8a78378 multicast=yes wireless=IEEE 802.11

3. Such problem could arise if too many clients are connected to AP which is clearly not my case. I'm trying to connect only one.

Hostapd is running fine, association is OK, dhcp server is running and configured but still no connection.

Code:

I'll try external ALFA dongle in case if there are some problems with last kali distro and internal wifi on RPi3. If anyone stuck (or solved) with the same problem please let me know.

Hi n3tr4k,

the latest raspberry pi images include the nexmon patch for the internal wifi adapter, which requires an additional step:

You must bring up a monitor interface before starting hostapd, e.g.

Code:

iw phy phy0 interface add mon0 type monitor && ifconfig mon0 up

You can see a write up of this peculiarity here.

For a working example of a hostapd implementation on the Raspberry Pi 3 with nexmon drivers, check "ras-ap.sh" & "mon0up" in this folder:

https://github.com/Re4son/Kali-Pi/tr...r/Menus/RAS-AP

Hope that helps

Thanks a lot re4son, I only had to assign static IP to wlan0 after that and everything worked. Cheers.

Sorry to bring up a zombie thread but i am having the same issues.

I have tried to follow the guide that is mentioned by OP
But there seems to be an issue with dhcpd that there is no service associated with it.

If OP could detail how he got things working that be great. Or i could create my own post since my scenario is i want to use an external adapter for better range.

I have the same problem. After the release of the current version (2018.3) something went wrong.
RPi3b+

me too, I'm using the raspberry pi3 b+ on the current version 2018.3. I can see the AP but when I'm trying to connect to it, it always say me that the password is wrong. Also, I've tried with Raspbian but this time it worked perfectly.. So the problem is Kali Linux itself. And in addition, as you can see in this tutorial :
1) https://null-byte.wonderhowto.com/ho...tspot-0180133/
At step number 2, it say that we need to configure the DHCPCD.conf file but this file only exist on Raspbian (I don't really what this file can do). If someone could help us, this will be great.. And sorry for my english :d

Thanks in advance.

I am also having this issue.

Code:

sudo iw phy phy0 interface add mon0 type monitor && ifconfig mon0 up

gives
command failed: Operation not supported (-95)

Gutted, I really thought this forum post was going to be the bottom of this rabbit hole at last.
I have the EXACT symptoms as OP.

@GigaJoules, a few things:
- This is an old thread, so, open a new one
- It is not the same issue as OP, he is trying to get AP mode running, you are trying to get monitor mode

In any case, use airmon-ng to put it in monitor mode, it works just fine.
