Nl80211 Driver Does Not Support Authentication Association Or Connect Commands
Kristin Klodzinski
I'm using a custom AM3351 board with Linux kernel 4.4.12 in ti-processor SDK v3.00.00.04. I'm having trouble using the RT8188EU driver found in the drivers/staging kernel config options. Initially it failed with the message that it was unable to find firmware file rtl8188eufw.bin, so I copied the binary from and placed in the /lib/firmware/rltwifi folder as recommended.
After this change, the module loads when I plug in my device, and I'm able to see my wlan0 device. The lsusb command also properly shows my device. I'm also able to scan for WiFi networks and see my local AP, so the driver must be working to some extent. However, I'm not able to connect to my access point with WPA authetication.
nl80211 driver does not support authentication association or connect commands

The error message indicates that the driver does not support authetication/association or connect commands. Is there a kernel config option that I'm overlooking? Or perhaps the firmware from lwfinger repo is not the correct binary? Please let me know if you have any suggestions.
wpa_supplicant is a cross-platform supplicant with support for WPA, WPA2 and WPA3 (IEEE 802.11i). It is suitable for desktops, laptops and embedded systems. It is the IEEE 802.1X/WPA component that is used in the client stations. It implements key negotiation with a WPA authenticator and it controls the roaming and IEEE 802.11 authentication/association of the wireless driver.
The first step to connect to an encrypted wireless network is having wpa_supplicant obtain authentication from a WPA authenticator. In order to do this, wpa_supplicant must be configured so that it will be able to submit the correct credentials to the authenticator.
In order to use wpa_cli, a control interface must be specified for wpa_supplicant, and it must be given the rights to update the configuration. Do this by creating a minimal configuration file:
If the SSID does not have password authentication, you must explicitly configure the network as keyless by replacing the command set_network 0 psk "passphrase" with set_network 0 key_mgmt NONE.
This connection method allows quickly connecting to a network whose SSID is already known, making use of wpa_passphrase, a command line tool which generates the minimal configuration needed by wpa_supplicant. For example:
For networks of varying complexity, possibly employing extensive use of EAP, it will be useful to maintain a customised configuration file. For an overview of the configuration with examples, refer to wpa_supplicant.conf(5); for details on all the supported configuration parameters, refer to the example file /usr/share/doc/wpa_supplicant/wpa_supplicant.conf.[1]
Further network blocks may be added manually, or using wpa_cli as illustrated in #Connecting with wpa_cli. In order to use wpa_cli, a control interface must be set with the ctrl_interface option. Setting ctrl_interface_group=wheel allows users belonging to such group to execute wpa_cli. This setting can be used to enable users without root access (or equivalent via sudo etc) to connect to wireless networks. Also add update_config=1 so that changes made with wpa_cli to example.conf can be saved. Note that any user that is a member of the ctrl_interface_group group will be able to make changes to the file if this is turned on.
fast_reauth=1 and ap_scan=1 are the wpa_supplicant options active globally at the time of writing. Whether you need them, or other global options too for that matter, depends on the type of network to connect to. If you need other global options, simply copy them over to the file from /usr/share/doc/wpa_supplicant/wpa_supplicant.conf.
Alternatively, wpa_cli set can be used to see options' status or set new ones. Multiple network blocks may be appended to this configuration: the supplicant will handle association to and roaming between all of them. The strongest signal defined with a network block usually is connected to by default, one may define priority= to influence behaviour. For example to auto-connect to any unsecured network as a fallback with the lowest priority:
Once you have finished the configuration file, you can optionally use it as a system-wide or per-interface default configuration by naming it according to the paths listed in #At boot (systemd). This also applies if you use additional network manager tools, which may rely on the paths (for example Dhcpcd#10-wpa_supplicant).
To connect a wired adapter using 802.1x/radius you will need to specify some configurations and enable the necessary service for the adapter. This is useful for headless servers using networkd.
wpa_cli can run in daemon mode and execute a specified script based on events from wpa_supplicant. Two events are supported: CONNECTED and DISCONNECTED. Some environment variables are available to the script, see wpa_cli(8) for details.
When connected to a wireless network with multiple access points, wpa_supplicant is typically responsible for roaming between access points. Choosing a new access point requires wpa_supplicant to perform a scan of available networks, which causes a brief interruption in connectivity to the current access point while the wireless radio scans other frequencies. After a scan, if wpa_supplicant detects a closer access point (BSSID) in the current network (SSID), in terms of signal strength (RSSI), it will re-associate to the closer access point.
The default configuration of wpa_supplicant has relatively timid roaming: it will rescan only when the association to the current access point is lost. This means that, if a client moves far away from its current access point, but not far enough to completely lose signal, the client will keep using the weak signal instead of roaming to a closer access point.
The above example will cause wpa_supplicant to scan every 30 seconds when the signal is weak (below -70), and every 3600 seconds otherwise. bgscan can be specified either in specific network blocks or globally for all networks.
In order to determine why you are unable to connect to an access point you can run wpa_supplicant with the -d flag for debug messages, wait a couple seconds then look for lines that list SSIDs and the reason they were not connected to. For example:
In this case we are trying to connect to an access point with the SSID home. The reason the connection fails is skip RSN IE - no mgmt frame protection enabled but AP requires it, so we need to add ieee80211w=2 to our configuration file.
If the command works to connect, and the user wishes to use systemd to manage the wireless connection, it is necessary to edit the wpa_supplicant@.service unit provided by the package and modify the ExecStart line accordingly:
When you use wireless to connect to network shares you might have the problem that the shutdown takes a very long time. That is because systemd runs against a 3 minute timeout. The reason is that WPA supplicant is shut down too early, i.e. before systemd tries to unmount the share(s). A bug report suggests a work-around by editing the wpa_supplicant@.service as follows:
wpa_supplicant may not work properly if directly passed via stdin particularly long or complex passphrases which include special characters. This may lead to errors such as failed 4-way WPA handshake, PSK may be wrong when launching wpa_supplicant.
In some instances it was found that storing the passphrase cleartext in the psk key of the wpa_supplicant.conf network block gave positive results (see [2]). However, this approach is rather insecure. Using wpa_cli to create this file instead of manually writing it gives the best results most of the time and therefore is the recommended way to proceed.
In addition, from version v2.10, wpa_supplicant relies on OpenSSL 3 which causes some compatibility issues to connect to eduroam. A workaround consists in downgrading wpa_supplicant to version v2.9 and installing OpenSSL 1.1 (see [3]).
I am trying to create an Access Point using TL-WN725 WiFi adapter in RaspberryPi 3 with buster OS version, but failing. It is showing "nl80211: Driver does not support authentication/association or connect commands" error when I try to start hostapd service. PFA for reference.
I also tried creating Access Point using older version of hostapd as described in this ( _USB_Wi-Fi_Adapters) link but didn't work.
As per my readings and understanding, creating Access Point is supported with RTL8188CUS Chip instead of RTL8188EUS. Right? Is yes, then please share a product link which support creating Access Point in RaspberryPi out-of-the box.
