I am trying to configure raspberry pi wifi module as AP and client at the same time on same wlan0 interface using Access point as WiFi router/repeater, optional with bridge this tutorial, the problem I am facing is that only one device gets connected to AP, if I try to connect second device the device goes to connected-disconnected-than continues saved state and do not gets connect. only the device which comes first gets connected none other, I have googled a lot but failed to find any solution. My files Configurations and logs are.

interface=ap@wlan0
#driver=nl80211
#ieee80211n=1
driver=nl80211
country_code=DE
ssid=embabcd

#macaddr_acl=0
auth_algs=1
wpa=2
wpa_passphrase=12345678emb
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP
rsn_pairwise=CCMP

bridge=br0

Note : I am not allowed to use any other interface like eth0 or external wifi module. what should I do now.

  • One observation - the procedure you linked WAS NOT designed for Ubuntu and you HAVE NOT explained WHAT YOU DID. You tagged hostapd & systemd-networkd which is incomprehensible! – Milliways Sep 16 '22 at 11:44
  • what else information should I provide?. – Muhammad Sep 16 '22 at 11:51
