Hi,

Recently I decided to switch my WIFI card from EMMY-W163 (datasheet: https://www.u-blox.com/sites/default/files/EMMY-W1_DataSheet_%28UBX-15011785%29.pdf) to WPEA-121N (https://www.sparklan.com/product/wpea-121n-ar9382-2t2r-wifi-module/). I am using a custom computer with Nitrogen6 SOM V2 (https://boundarydevices.com/product/nitrogen6-som-v2/). I use ubuntu 16.04.1LTS, kernel 4.1.15.

One of tasks I preform on this computer is to create a hotspot.

When using EMMY card, I can create hotspot using create_ap script with config:

CHANNEL=6 

GATEWAY=192.168.10.1 

NEW_MACADDR= 

SSID=MySSID 

PASSPHRASE=MYPassword 

WIFI_IFACE=mlan1 

WPA_VERSION=1+2 

ETC_HOSTS=0 

DHCP_DNS=gateway 

NO_DNS=1 

HIDDEN=0 

ISOLATE_CLIENTS=0 

SHARE_METHOD=none 

IEEE80211N=1 

IEEE80211AC=0 

HT_CAPAB= 

VHT_CAPAB= 

DRIVER=nl80211 

NO_VIRT=1 

COUNTRY=DE 

FREQ_BAND=2.4 

DAEMONIZE=0 

NO_HAVEGED=0 

INTERNET_IFACE= 

USE_PSK=0

It works without any problems. Now when I change card for WPEA and try to create hotspot using create_ap (modifying config parameter WIFI_IFACE first) I get.

lspci -v

I checked that WPEA card supports AP mode:

iw list 

* 

Supported interface modes: 

		 * IBSS 

		 * managed 

		 * AP 

		 * AP/VLAN 

		 * WDS 

		 * monitor 

		 * P2P-client 

		 * P2P-GO 

*

Running create_ap on computer with WPEA card:

sudo /opt/scripts/create_ap --config /etc/opt/config/create_ap.conf 

Config dir: /tmp/create_ap.wlp1s0.conf.W9XzBnhu 

PID: 7302 

Network Manager found, set wlp1s0 as unmanaged device... DONE

Low entropy warning also occurs when I run this script on EMMY card so I do not think it is causing problems with hotspot.

But wifi network cannot be found (it is also not a hidden network)

When I try to connect to other Wi-Fi, I can only connect to ones that are not encrypted. When trying to connect to encrypted ones I get:

sudo nmcli device wifi connect mynetwork password mypassword 

Error: Connection activation failed: (7) Secrets were required, but not provided.

I also tried to set hotspot using nmcli/nmtui and hostapd commends, with similar results.

For me the most important thing is to use the device as a hotspot.
