Bridged AP does not work on BananaPiPro (Armbian_community_26.8.0-trunk.170_Bananapipro_trixie_current_6.18.35_minimal)

I tried to build an bridged AP so that I can reach the Internet from a WiFi net spawned from the BananaPiPro. By this I followed the procedure from armbian-config (config.network.sh).

 

After install the AP is shown in the login screen:

 

WiFi AP:      SSID: (BPi), channel 7 (2442 MHz), width: 20 MHz, center1: 2442 MHz

 

When I try to connect from my mobile phone it either says "connecting without Internet".

The output in syslog is then:

 

026-07-06T12:35:02.645970+02:00 bananapipro hostapd: wlan0: STA 22:50:7b:ac:e3:2e IEEE 802.11: associated

Ort otherwise the phone just says "cannot connect".

 

My netplan file is as follows:

 

network:
  version: 2
  renderer: networkd
  ethernets:
    end0:
      dhcp4: false
      dhcp6: false
      macaddress: "02:cd:08:83:3c:f3"
    wlan0:
      dhcp4: false
      dhcp6: false
  bridges:
    br0:
      addresses:
      - "192.168.178.29/24"
      nameservers:
        addresses:
        - 9.9.9.9
        - 1.1.1.1
      interfaces:
      - wlan0
      - end0
      routes:
      - metric: 200
        to: default
        via: "192.168.178.1"

 

The hostapd.conf is:

 

interface=wlan0
driver=nl80211
ssid=BPi
hw_mode=g
channel=7
wmm_enabled=0
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=secret
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

ctrl_interface=/var/run/hostapd
ctrl_interface_group=0

ieee80211n=1
ht_capab=[DSSS_CK-40][HT20+]

preamble=1

bridge=br0

 

The output of network list is:

 

root@bananapipro:/etc/hostapd# networkctl list
IDX LINK  TYPE     OPERATIONAL SETUP     
  1 lo    loopback carrier     unmanaged
  2 end0  ether    enslaved    configured
  3 br0   bridge   routable    configured
  4 wlan0 wlan     enslaved    failed   

 

Does anybody have an idea where to look further for a solution? As I have an AP running on my other BananaPiPro (Bookworm CLI / Networkmanager, manual config, not bridged) it cannot be a complete HW limitation, I think.

I had a quick look at the script, but it is too complex for me to see what could be wrong. Also there is netplan layer in between that I am not familiar with anymore. Maybe you can look at what is generated in terms of systemd-networkd files (e.g. in /etc/systemd/network/ ). And also use commands like ip route etc to see the actual state.

Well, netplan is the advertised / provided solution for Armbian. So when you look into /etc/systemd/network you find a readme from armbian pointing you to /etc/netplan. I think what netplan does is generating the following files for systemd-networkd under /run/systemd/network:

 

10-netplan-end0.network:

[Match]
Name=end0

[Link]
MACAddress=02:cd:08:83:3c:f3

[Network]
LinkLocalAddressing=no
Bridge=br0

 

10-netplan-wlan0.network

[Match]
Name=wlan0

[Network]
LinkLocalAddressing=no
Bridge=br0

 

10-netplan-br0.network 

[Match]
Name=br0

[Network]
LinkLocalAddressing=ipv6
Address=192.168.178.29/24
DNS=9.9.9.9
DNS=1.1.1.1
ConfigureWithoutCarrier=yes

[Route]
Destination=0.0.0.0/0
Gateway=192.168.178.1
Metric=200

 

10-netplan-br0.netdev 

[NetDev]
Name=br0
Kind=bridge

 

And this is the ip output:

 

ip route:

default via 192.168.178.1 dev br0 proto static metric 200 
192.168.178.0/24 dev br0 proto kernel scope link src 192.168.178.29
