This is the same wireless solution found on the Raspberry Pi 4 Model B, so you get the same reliability and speed.

Wi-Fi Specifications

The Raspberry Pi 400 uses a Cypress CYW43455 wireless chip, which provides the following Wi-Fi capabilities:

  • Standard: IEEE 802.11ac (Wi-Fi 5)
  • Bands: Dual-band 2.4 GHz and 5 GHz
  • Modes: Station (client) and Access Point (soft AP)
  • Security: WPA, WPA2, and WPA3 (depending on OS version)
  • Antenna: Internal, built into the PCB

The 802.11ac support means the Raspberry Pi 400 can take advantage of 5 GHz networks, which offer faster speeds and less interference than the older 2.4 GHz band. In practice, real-world throughput typically reaches around 100 to 150 Mbps on a good 5 GHz connection, which is more than enough for streaming, browsing, and general desktop use.

Bluetooth and Other Wireless Features

In addition to Wi-Fi, the Raspberry Pi 400 includes Bluetooth 5.0. This allows you to connect wireless keyboards, mice, headphones, speakers, and other Bluetooth peripherals without using a USB receiver. Bluetooth 5.0 offers improved range and speed over older versions, making it a solid choice for wireless accessories.

The wireless module also supports Bluetooth Low Energy (BLE), which is useful for IoT projects and connecting to sensors or smart home devices. Combined with Wi-Fi, this makes the Raspberry Pi 400 a well-rounded wireless platform for both desktop and embedded applications.

Raspberry Pi 400 vs Other Raspberry Pi Models

To put the wireless capabilities of the Raspberry Pi 400 in context, here is a comparison with other popular Raspberry Pi models:

Model Wi-Fi Bluetooth Ethernet Form Factor
Raspberry Pi 400 802.11ac (2.4/5 GHz) 5.0 Gigabit Keyboard (all-in-one)
Raspberry Pi 4 Model B 802.11ac (2.4/5 GHz) 5.0 Gigabit Bare board
Raspberry Pi 3 Model B+ 802.11ac (2.4/5 GHz) 4.2 Gigabit (limited to 300 Mbps) Bare board
Raspberry Pi Zero 2 W 802.11n (2.4 GHz only) 4.2 None (USB OTG) Compact board
Raspberry Pi 5 802.11ac (2.4/5 GHz) 5.0 Gigabit Bare board

As you can see, the Raspberry Pi 400 matches the Raspberry Pi 4 Model B in wireless specifications. The main difference is the form factor and the integrated keyboard. If you need the most compact wireless Pi, the Zero 2 W is an option, but it only supports 2.4 GHz Wi-Fi.

How to Connect Raspberry Pi 400 to Wi-Fi

Connecting your Raspberry Pi 400 to a Wi-Fi network is straightforward. There are three common methods depending on whether you prefer a graphical interface or the command line.

Method 1: Using the Desktop GUI

If you are running Raspberry Pi OS with a desktop environment, connecting to Wi-Fi is as easy as on any laptop.

  1. Click the network icon in the top-right corner of the taskbar.
  2. A list of available Wi-Fi networks will appear.
  3. Select your network name (SSID).
  4. Enter the Wi-Fi password when prompted.
  5. Click OK or Connect.
  6. Wait a few seconds for the connection to establish. The network icon will change to show signal strength.

Once connected, you can verify the connection by opening a terminal and running:

ping -c 4 google.com

If you receive replies, your internet connection is working.

Method 2: Using the Command Line

If you are using a headless setup or prefer the terminal, you can use the raspi-config tool or NetworkManager commands.

Using raspi-config:

  1. Open a terminal and run sudo raspi-config.
  2. Navigate to System Options, then Wireless LAN.
  3. Enter your SSID and password.
  4. Exit raspi-config and reboot if prompted.

Using nmcli (NetworkManager):

nmcli device wifi list
nmcli device wifi connect "YourSSID" password "YourPassword"

The first command lists available networks. The second connects to your chosen network and saves the profile for future use.

Method 3: Editing wpa_supplicant.conf

For advanced users or headless setups where you want to pre-configure Wi-Fi before first boot, you can edit the wpa_supplicant.conf file.

  1. Mount the boot partition of your microSD card on another computer.
  2. Create or edit a file named wpa_supplicant.conf in the root of the boot partition.
  3. Add the following content:
country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="YourNetworkName"
    psk="YourPassword"
    key_mgmt=WPA-PSK
}
  1. Save the file and safely eject the SD card.
  2. Insert the card into the Raspberry Pi 400 and power it on. It will automatically connect to the specified network.

Make sure to set the correct country code, as this affects which wireless channels are available and is required for legal compliance in many regions.

Troubleshooting Wi-Fi Issues

Even though the Raspberry Pi 400 has reliable built-in Wi-Fi, you may occasionally encounter connection problems. Here are common issues and how to resolve them.

  • No networks found: Check that Wi-Fi is not disabled. Run rfkill list and ensure the wireless device is not soft-blocked. Unblock with sudo rfkill unblock wifi.
  • Connection drops frequently: This can be caused by power management. Disable Wi-Fi power saving with sudo iw dev wlan0 set power_save off.
  • Slow speeds: Ensure you are connected to a 5 GHz network rather than 2.4 GHz. Check signal strength and reduce distance from the router.
  • Authentication failed: Double-check your password and ensure the security type matches (WPA2-PSK is most common).
  • Country code errors: If channels are missing, set the correct country code in /etc/wpa_supplicant/wpa_supplicant.conf or via raspi-config.

If problems persist, updating the OS and firmware can resolve many wireless driver issues:

sudo apt update
sudo apt full-upgrade
sudo rpi-eeprom-update -a

Wi-Fi Performance and Range

The Raspberry Pi 400’s Wi-Fi performance is solid for a compact device. On a 5 GHz network close to the router, you can expect speeds in the range of 100 to 150 Mbps. On 2.4 GHz, speeds are typically lower, around 40 to 70 Mbps, but range is better and penetration through walls is stronger.

Because the antenna is internal and embedded in the keyboard PCB, placement matters. For best results, position the Raspberry Pi 400 so that the keyboard is not blocked by metal objects or thick walls. Avoid placing it inside a metal enclosure or directly behind a large monitor with metal shielding.

If you need maximum throughput or a very stable connection for tasks like running a server or transferring large files, the built-in Gigabit Ethernet port is the better choice. A wired connection will consistently outperform Wi-Fi and is immune to wireless interference.
