WIFI issues with my turtlebot3 burger [closed]

edit

you can set the time and date using the sudo timedatectl <command>

can you add the 50-cloud-init.yaml in your question? You can remove the password. But your password in the file should be inside this : " " You might also need to do sudo netplan generate and sudo netplan apply.

Thank you for your answer!

The 50-cloud-init.yaml :

# This file is generated from information provided by the datasource.  Changes
# to it will not persist across an instance reboot.  To disable cloud-init's
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp4: yes
      dhcp6: yes
      optional: true
  wifis:
    wlan0:
      dhcp4: yes
      dhcp6: yes
      access-points:
        TURTLEBOT:
          password: "my_password"

I used the two netplan command and reboot and nothing change, it always refuse to connect directly to the router, it needs the phone AP

Unfortunately, I did not had the 50-cloud-init.yaml So I added my wifi details in the /etc/wpa_supplicant/wpa_supplicant.conf

It looks like this, You can also try with this method.

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=FR

network={
                ssid="TP-Link-----"
                psk="your_password"
                key_mgmt=WPA-PSK
}

Could this be the issue?

# This file is generated from information provided by the datasource.  Changes

# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}

As for how to fix this. Simply said, this isn't a ROS problem. I get why you posted it here, don't get me wrong. However, your actual question is "I want to connect a Raspberry PI running Ubuntu 20.04 server to my router". It might be easier to simply google "raspberry pi ubuntu 20.04 server connect to wifi" and find a tutorial to follow. As I said, I get why you posted it here, but googling it as a problem that's separated from ROS might give you a better answer.

Unfortunately, I tried to add /etc/wpa_supplicant/wpa_supplicant.conf file but it didn't change anything and I also tried to create the /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg file and it didn't works too.

In fact Joe, I first posted this question on the raspberry forum and didn't find answer. But I will follow your advice and try on ubuntu forum too. I followed differents tutorials but didn't change anything, it works but only if i use my phone AP as a relay to my router

I asked on this forum : French Ubuntu Forum: My topic Sorry it's in French but just follow the step of this link (in english):

In case the Raspberry Pi and your wifi router uses different WiFi channel, this could happen. Please try setting your country code in the /etc/default/crda file as below. By default the REGDOMAIN is empty.

REGDOMAIN=US

hello, did you managed to solve this problem? mind share it with me?

I did all below, it still didn't work for me.

1. set the 50-cloud-init.yaml, generate and apply netplan, reboot
2. added wpa_supplicant.conf and edit accordingly
3. created 99-disable-network-config,cfg and edit accordingly
4. change the region in /etc/default/crda
5. couldn't access iwconfig, unable to install as there's no internet connection
6. tried to connect RPi with network cable - didn't detect any network connection, I've tried to connect the network cable to another PC port, it does give internet connection
7. USB tethering - I'm not sure whether the cable has a problem or what, it didn't detect to my phone, and the rasp pi sometimes auto shutdown when the cable is attached to the usb port

highly appreciated if someone could help me urgent!

Hello,

I managed to connect my Tb3 to the network by changing the region but it seems that you already tried so I don't know the solution ...

Which OS did you install ?
