Can't set Wireless LAN (raspi-config - Pi4B)

[Godrigos]

I tried in two fresh installs and after activation, basic configuration and enabling SSH, when I use raspi-config to set my wifi I get the following error:

Traceback (most recent call last): File "/usr/sbin/netplan", line 23, in <module> netplan.main() File "/usr/share/netplan/netplan/cli/core.py", line 50, in main self.run_command() File "/usr/share/netplan/netplan/cli/utils.py", line 241, in run_command self.func() File "/usr/share/netplan/netplan/cli/commands/set.py", line 50, in run self.run_command() File "/usr/share/netplan/netplan/cli/utils.py", line 241, in run_command self.func() File "/usr/share/netplan/netplan/cli/commands/set.py", line 72, in command_set libnetplan.create_yaml_patch(yaml_path, value, tmp) File "/usr/share/netplan/netplan/libnetplan.py", line 501, in create_yaml_patch _checked_lib_call(lib.netplan_util_create_yaml_patch, File "/usr/share/netplan/netplan/libnetplan.py", line 79, in _checked_lib_call raise LibNetplanException(err.contents.message.decode('utf-8')) netplan.libnetplan.LibNetplanException: Error parsing YAML: did not find expected ',' or '}'

And no wifi connection.

Hi, I had the same problem here with an RP4B too. I installed the older version of ncp v1.54.0 as the wifi seemed to work back then. The configuration through raspi-config didn't work out neither but I managed to activate the wifi installing and running armbian-config. I guess doing the same thing on the latest version of ncp should work too, it seemed to me a good way to get around the issue.

Thanks for the tip. Will try it later.

@Peppeeeerrrr Thank you, seems like a good workaround.

The issue itself is very likely an upstream issue with Armbian for the RPi.

@Godrigos If you are able to confirm that the workaround works for you, we can close this issue (and I'll ask the Wiki team to add it to the NCP wiki).

[Godrigos]

Unfortunatly, even if I can install the armbian-config, it does not present options for wifi configurations, there is a warning that missing drivers may limit the configuration options.

I solved my issue with an ugly long cable, lol. But no wifi. Thanks for the attention guys.

Sad. I need wifi acces too. I dont want use cable, coz this pi4 is hiddne uder bed :D Solved. Install network-manager and Wifi is enabled, so I can connect nextcloudpi to WiFi :) Hope it help someone else

You probably now have NTP broken. See this question: https://unix.stackexchange.com/questions/788787/unable-to-get-ntp-systemd-timesyncd-working-over-wifi

Hello all, Hello @3kimm0

my workaround for Raspi 4B (maybe Pi 5 #2016 ) WLAN setup on

"NextcloudPi v1.55.3 is up to date" "v24.11.1 for Raspberry Pi 4 running Armbian Linux 6.6.63-current-bcm2711"

Check with iwconfig and/or networkctl if wlan0 module is loaded / installed

sudo iwconfig lo no wireless extensions. end0 no wireless extensions. wlan0 IEEE 802.11 [...]

sudo networkctl IDX LINK TYPE OPERATIONAL SETUP 1 lo loopback carrier unmanaged 2 end0 ether routable configured 3 wlan0 wlan [...]

if it's not listed/ installed

sudo apt install  firmware-brcm80211
sudo reboot

and check again, if successfull

add netplan config sudo nano /etc/netplan/10-netplan-wlan0.yaml take care about yaml spacing/format

# Added by Armbian

# Reference: https://netplan.readthedocs.io/en/stable/netplan-yaml/
#
# Let systemd-networkd manage all Ethernet devices on this system, but be configured by Netplan.

network:
  version: 2
  renderer: networkd
  wifis:
    wlan0:
      dhcp4: true
      dhcp6: false
      access-points:
        "YourWLAN-SSID-Name":
          auth:
            key-management: "psk"
            password: "YourStrongSecretPW"

sudo chown root:root /etc/netplan/10-netplan-wlan0.yaml
sudo chmod 600 /etc/netplan/10-netplan-wlan0.yaml

check your new config sudo netplan try if ok sudo netplan apply

should look like this sudo networkctl IDX LINK TYPE OPERATIONAL SETUP 1 lo loopback carrier unmanaged 2 end0 ether routable configured 3 wlan0 wlan routable configured

check ip adress / dhcp

ip a

Based on the default metric 600 for wlan0 your lan access is preferred. Disconnect lan cable or take down lan to check/use wlan0 - take care open session will be uselesse/closed sudo networkctl down end0

Expanding marco-aa solution,

If sudo netplan try throws Cannot call openvswitch: ovsdb-server.service is not running. Do sudo apt install openvswitch-switch-dpdk

and continue with other steps

System: Pi4B, fresh new install NCPi 30.0.1 (and had to upgrade to 30.0.8)

[SchroedersKater]

I tried all the suggestions here and in the other threads, but had no success. The WiFi connection is visible in my router, but there is not way to access it. I can't access it via SSH nor can I via browser. Only the ethernet connection is working.

Does someone have an idea what else I could try?

Here is some information from my system:

How did you install your instance? How old is it?

The recent rpi images are armbian based, you should do your network configuration with armbian-config (maybe it must be installed)l Keep in mind your contry code must be configured to get a wifi connection.
