How to Turn a Raspberry Pi Into a Wi-Fi Access Point
of raspberry pi A truly versatile technology. With Pi, you can learn to code, build robots, manipulate complex sensor data, and even change the old Turn your printer into a web-enabled deviceIf you have an old Raspberry Pi and it’s getting dusty, there’s a quick and easy project to add Wi-Fi connectivity without spending extra money.
of Latest Raspberry Pi OS release I saw the beta of Network Manager, a new tool for Raspberry Pi that replaces dhcpcd as a way to manage networks on the Pi. This new tool provides a simple GUI-based way to configure a spare Raspberry Pi as a wireless access point. If you need to expand your network setup or add Wi-Fi in hard to reach places, this is the one for you.
Follow the steps necessary to configure your Raspberry Pi as a wireless access point and start the access point every time you boot your Pi. Best of all, this project works on Raspberry Pi 3B, 3B+ and the latest Raspberry Pi 4.
Wi-Fi access point network manager setup
The Network Manager application is a new addition to the Raspberry Pi OS. At the time of writing this is still in beta and some additional steps are required to switch from the old dhcpcd application to Network Manager.
This section details the steps necessary to configure the Pi to use the new networking tools.
1. Setting up your Raspberry Pi If you don’t already have one.See our guide How to set up your Raspberry Pi.
2. Connect your Raspberry Pi to an Ethernet connection. Your Pi will be a wireless access point, but the connection to your router will be via Ethernet. This will give you the strongest connection and guarantee the highest possible speeds.
3. open a terminal window With an SSH connection to your Pi or Raspberry Pi.
Four. Make sure your Raspberry Pi is up to date. By running the latest update command. This isn’t strictly necessary as the latest Raspberry Pi OS release is already fairly current. Consider this a best practice.
sudo apt update
sudo apt upgrade -y
Five. Use raspi-config to edit the Raspberry Pi’s configuration. The network manager option is currently only available via raspi-config and not via the GUI editor.
sudo raspi-config
6. Use the cursor keys to[詳細オプション]and press Enter.
7. Go to Network Config and press Enter.
8. [ネットワーク マネージャー]and select[OK]Click.
9. [OK]Click.
Ten. [完了]Click.
11. [はい]Select to reboot.
Setting up an access point on the Raspberry Pi
The access point uses the Raspberry Pi’s onboard Wi-Fi chip to provide Wi-Fi access. This section configures the access point’s name and security. Note that the Raspberry Pi must be connected to your home Internet connection via Ethernet. This will give you the best possible connection.
1. [ネットワーク]Left click on the icon,[詳細オプション]then[ワイヤレス ホットスポットの作成]Choose.
2. Set the network name of the access point, Wi-Fi security to WPA2, When Then set the AP password.Click create save.
3. Reboot your Raspberry Pi.
Four. Click the network icon. Make sure the access point is active.
Configure the Raspberry Pi access point to boot on boot
We want to turn this project into an electrical appliance. To do that, you’ll need to tweak your access point’s settings so that it wakes up when you turn on the Raspberry Pi. Luckily, this only takes a few steps.
1. Click the network icon. When [詳細オプション]>>[接続の編集]Click. This will allow you to change the access point settings.
2, Select the wireless access point name, When Click the settings gear to make changes.
3.[全般]tab, Check the “Automatically connect with priority” box and set the priority to 0. Click Save. make changes. This will set the access point to boot every time the Pi boots.
Connect to Raspberry Pi Access Point
The access point works like any other Wi-Fi router/access point.
1. Connect your computer/mobile device to the new access point. It will be displayed with the specified name.
2. Or on a Raspberry Pi[ネットワーク]Click the icon,[詳細オプション]>>[接続情報]Choose.
3. Scan the QR code with a compatible device to automatically connect to the access point. The information dialog contains all the information you need for your access point.
