Quick Answer: Does the Raspberry Pi Have Wifi?

So, does the Raspberry Pi Have Wifi? The short answer is: it depends on the model. Every Raspberry Pi released from the Raspberry Pi 3 onward includes built-in Wifi (with a few exceptions in the Zero line). Models older than the Pi 3, including the original Raspberry Pi 1 and Raspberry Pi 2, do not have built-in Wifi. They rely on Ethernet or a USB Wifi adapter.

If you want a quick rule of thumb: if your Pi is a Raspberry Pi 3, 4, 5, 400, Zero W, Zero 2 W, or newer, it has Wifi. If it is a Raspberry Pi 1, 2, Zero (non-W), or Pico, it does not.

Understanding Raspberry Pi Generations

Before diving into each model, it helps to understand how the Raspberry Pi Foundation names and releases boards. The main line (Raspberry Pi 1, 2, 3, 4, 5) gets a new generation roughly every few years, with smaller revisions in between (Model A, Model B, B+, etc.). Alongside the main line, there are specialized boards like the Zero (tiny and cheap), the 400 (keyboard form factor), and the Pico (microcontroller).

Wifi support arrived as a major milestone with the Raspberry Pi 3 in 2016. Before that, the Foundation kept costs low by leaving wireless networking out and letting users add it via USB. After the Pi 3, built-in Wifi became standard for the main line and most Zero variants.

Raspberry Pi 1 (Original Models)

The original Raspberry Pi, released in 2012, did not include Wifi. This includes the Raspberry Pi Model B, Model A, Model B+, and Model A+. These boards featured a 10/100 Ethernet port (on Model B variants) but no wireless radio of any kind.

So when asking “Does the Raspberry Pi Have Wifi?” for these early boards, the answer is clearly no. Users who needed wireless connectivity had to plug in a USB Wifi dongle. Many popular dongles of the era used the Realtek RTL8188 or Ralink RT5370 chipsets.

Pi 1 Variants at a Glance

  • Raspberry Pi Model B (2012): Ethernet only, no Wifi.
  • Raspberry Pi Model A (2013): No Ethernet, no Wifi.
  • Raspberry Pi Model B+ (2014): Ethernet only, no Wifi.
  • Raspberry Pi Model A+ (2014): No Ethernet, no Wifi.

Raspberry Pi 2

The Raspberry Pi 2, released in 2015, brought a major CPU upgrade with its quad-core ARM Cortex-A7 processor. However, it still did not include Wifi. Like the Pi 1, it offered a 10/100 Ethernet port and relied on USB for wireless networking.

So does the Raspberry Pi 2 Have Wifi? No. If you own a Pi 2 and want wireless connectivity, you will need a USB Wifi adapter or an Ethernet cable.

Raspberry Pi 3 (Wifi Arrives)

The Raspberry Pi 3 Model B, released in February 2016, was the first mainstream Pi to include built-in Wifi. It shipped with a Broadcom BCM43438 wireless chip supporting 2.4 GHz 802.11n Wifi and Bluetooth 4.1.

This was a turning point. For the first time, you could take a Raspberry Pi out of the box, power it on, and connect to a wireless network without any extra hardware. This is when the question “Does the Raspberry Pi Have Wifi?” started getting a real yes for the default model.

Raspberry Pi 3 Model B+

Released in March 2018, the Raspberry Pi 3 Model B+ improved on the original Pi 3 with a better wireless chip. It uses the Cypress CYW43455, supporting dual-band 2.4 GHz and 5 GHz 802.11ac Wifi, plus Bluetooth 4.2.

The 5 GHz support and faster throughput made a noticeable difference for streaming, file transfers, and general network responsiveness. If you have a Pi 3 B+, you get solid dual-band Wifi out of the box.

Raspberry Pi 4

The Raspberry Pi 4, released in June 2019, continued the built-in Wifi tradition. It uses the same Cypress CYW43455 chip as the Pi 3 B+, offering dual-band 2.4 GHz and 5 GHz 802.11ac Wifi and Bluetooth 5.0.

The Pi 4 also upgraded to Gigabit Ethernet, giving users both fast wired and wireless options. So yes, the Raspberry Pi 4 does have Wifi, and it is one of the most capable wireless Pi models to date.

Raspberry Pi 400

The Raspberry Pi 400 is essentially a Raspberry Pi 4 built into a keyboard. Released in 2020, it includes the same wireless hardware as the Pi 4: dual-band 802.11ac Wifi and Bluetooth 5.0.

Because it is designed as a desktop computer, the Pi 400 is a convenient all-in-one device with Wifi ready to go. So the answer to “Does the Raspberry Pi 400 Have Wifi?” is a definite yes.

Raspberry Pi Zero Series

The Zero line is where things get interesting, because not every Zero model includes Wifi.

Raspberry Pi Zero (Original)

The original Raspberry Pi Zero, released in 2015, is a tiny, ultra-cheap board. It has no Wifi and no Ethernet. It is designed for minimal cost and size, and users must add wireless via USB (using an OTG adapter) or use a wired connection through a USB Ethernet adapter.

Raspberry Pi Zero W

Released in 2017, the Raspberry Pi Zero W added built-in Wifi and Bluetooth using the same BCM43438 chip as the Pi 3. This made the Zero W incredibly popular for IoT projects, sensors, and compact builds.

Raspberry Pi Zero 2 W

Released in 2021, the Raspberry Pi Zero 2 W upgrades to a quad-core processor and keeps built-in Wifi and Bluetooth (2.4 GHz 802.11n). It is a major performance boost over the original Zero W while staying in the same tiny form factor.

Raspberry Pi 5

The Raspberry Pi 5, released in late 2023, is the latest main-line board. It includes built-in Wifi (2.4 GHz and 5 GHz) and Bluetooth 5.0, plus a faster CPU, more RAM options, and PCIe support.

So does the Raspberry Pi 5 Have Wifi? Yes, absolutely. It continues the standard set by the Pi 3 and later models.

Raspberry Pi Pico

The Raspberry Pi Pico is a microcontroller board, not a full computer. The original Pico has no Wifi. However, the Raspberry Pi Pico W (released 2022) adds Wifi (2.4 GHz 802.11n) and Bluetooth via the CYW43439 chip. The Pico 2 W continues this trend.

So if you are asking “Does the Raspberry Pi Pico Have Wifi?” the answer is: the base Pico no, but the Pico W yes.

How to Check If Your Pi Has Wifi

If you are unsure which model you own, here are a few ways to check whether your board has Wifi.

Visual Inspection

Look at the board. Wifi-enabled Pis usually have a small metal can (the wireless module) and a printed antenna trace. The original Pi 1 and Pi 2 lack this. The Zero W has a small antenna area near the GPIO header. If you see no wireless module and no antenna trace, your Pi probably does not have Wifi.

Using the Command Line

On a running Raspberry Pi OS, you can check for a wireless interface with this command:

iwconfig

If you see a wlan0 interface listed, your Pi has Wifi. You can also run:

ip a | grep wlan

If nothing appears, your board likely has no wireless radio.

Identifying Your Model

You can identify your Pi model with:

cat /proc/device-tree/model

This prints the full model name, which you can cross-reference with the table above to answer “Does the Raspberry Pi Have Wifi?” for your specific board.

How to Connect Your Raspberry Pi to Wifi

If your Pi does have Wifi, connecting is straightforward. Here is a step-by-step guide.

  1. Boot your Raspberry Pi and log in (via desktop or SSH).
  2. Open the terminal or use the desktop Wifi icon in the top-right corner.
  3. If using the desktop, click the Wifi icon, select your network, and enter the password.
  4. If using the terminal, edit the wpa_supplicant file: sudo nano /etc/wpa_supplicant/wpa_supplicant.conf.
  5. Add your network details:
network={
    ssid="YourNetworkName"
    psk="YourPassword"
}
  1. Save the file (Ctrl+O, Enter, Ctrl+X) and restart networking or reboot.
  2. Verify the connection with ping google.com or check ip a.

On newer Raspberry Pi OS versions, you can also use raspi-config to set up Wifi interactively, which is often easier for beginners.

Adding Wifi to a Non-Wifi Raspberry Pi

If your Pi does not have built-in Wifi, you are not out of luck. Here are the common options.

USB Wifi Dongle

The most common solution is a USB Wifi adapter. Plug it into a USB port (or use an OTG adapter on a Zero), and Raspberry Pi OS usually recognizes it automatically. Popular chipsets include Realtek RTL8188 and MediaTek MT7601.

Ethernet Connection

If Wifi is not strictly necessary, a wired Ethernet connection is often faster and more reliable. Most Pi models (except Model A variants and the Zero) include an Ethernet port.

USB Tethering

You can share a phone’s internet connection over USB. This is handy for temporary setups or when you have no router nearby.

Tips and Best Practices

  • Check your model first: Always verify which Pi you own before assuming Wifi is available. This avoids frustration during setup.
  • Use 5 GHz when possible: On dual-band models, 5 GHz offers faster speeds and less interference, though range is shorter.
  • Keep your OS updated: Wireless drivers and firmware improve with updates. Run sudo apt update && sudo apt upgrade regularly.
  • Mind the antenna: On boards with PCB antennas, avoid covering the antenna area with metal cases or heatsinks that block the signal.
  • Consider power: Wifi draws extra power. Use a quality power supply (especially on Pi 4 and Pi 5) to avoid undervoltage issues.
  • For IoT projects: The Zero W and Zero 2 W are excellent low-cost, low-power Wifi-enabled options.
  • Secure your network: Use WPA2 or WPA3 and a strong password. Avoid open networks for Pi projects handling sensitive data.
