Ubuntu 16.04.1 LTS: Hotspot created but cannot be discovered

Post by zyczy »

Hi,

Recently I decided to switch my WIFI card from EMMY-W163 (datasheet: https://www.u-blox.com/sites/default/fi ... 785%29.pdf) to WPEA-121N (https://www.sparklan.com/product/wpea-1 ... fi-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:

Code: Select all

  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.

Code: Select all

 lspci -v

I checked that WPEA card supports AP mode:

Code: Select all

  iw list 
    * 
    Supported interface modes: 
    		 * IBSS 
    		 * managed 
    		 * AP 
    		 * AP/VLAN 
    		 * WDS 
    		 * monitor 
    		 * P2P-client 
    
    		 * P2P-GO 
     *
Running create_ap on computer with WPEA card:

Code: Select all

  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

    WARN: Low entropy detected. We recommend you to install `haveged' 
    Configuration file: /tmp/create_ap.wlp1s0.conf.W9XzBnhu/hostapd.conf 
    wlp1s0: interface state UNINITIALIZED->COUNTRY_UPDATE

    WPA: Not enough entropy in random pool for secure operations - update keys later when the first station connects 
    wlp1s0: interface state COUNTRY_UPDATE->ENABLED 
    wlp1s0: AP-ENABLED
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:

Code: Select all

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.

The same thread has been created on Askubuntu as well: Hotspot created but cannot be discovered
