Question:

How do I set up concurrent APSTA in Linux-based WLAN chips?

Answer:

In order to set up concurrent Access Point (AP) and STA (Station) for WLAN chips hosted by a Linux-based system, you must first install the following utilities and drivers listed as pre-requisites before proceeding with the instructions to set up APSTA.

Follow these steps to install APSTA in Linux-based WLAN chips:

1. Configure the wpa_supplicant daemon with the credentials/details of the AP to which your STA must connect. For this, modify the wpa_suplicant.conf config file.

>>>vi /etc/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant

ctrl_interface_group=0

update_config=1

network={

ssid=<YourSSID> #ssid of your AP to which the STA connects.

psk=<YourPassphrase> #Passphrase of the AP

  }

2. Configure the hostapd daemon with credentials/details of the AP that you want to set up.

>>> vi /etc/hostapd.conf

interface=wlan1

channel=11

ssid=<Router-Name>

wpa=1

wpa_passphrase=<Passphrase>

#above are the major changes to made in the hostapd.conf

3. Kill the wpa_supplicant daemon that is already running.

>>>grep -aux | grep wpa_supplicant

>>>killall wpa_supplicant

4. Remove the existing interface of the supplicant.

>>>rm -rf /var/run/wpa_supplicant/wlan0

5. Set up the IP address of the AP and start the wpa_supplicant with the nl80211 driver.

>>>ifconfig wlan0 192.168.1.3

>>>wpa_supplicant -D nl80211 -i wlan0 -c /etc/wpa_supplicant.conf -B &

6. Enable the network and check the status of the connection using the client application of the wpa_supplicant.

>>>wpa_cli -p /var/run/wpa_supplicant -i wlan0 enable_network 0

>>>wpa_cli -p /var/run/wpa_supplicant -i wlan0 status

7. Start the dhcp client that needs to be leased out to an IP from your dhcp server. If your AP/router supports static, you can set up a static IP as well using ifconfig.

>>>udhcpc -i wlan0 up

8. Set up the AP by running the hostapd daemon with the relevant configuration file and entropy binary for 4-way handshake.

>>>./hostapd /etc/hostapd.conf -e entropy.bin -B &
