Usually, no. Most Raspberry Pi boards have Wi-Fi built in, but a few older models do not. Check your exact board first: a USB Wi-Fi adapter is useful when the board lacks wireless or when you have confirmed that its built-in Wi-Fi cannot meet a specific requirement.
Which Raspberry Pi models have built-in Wi-Fi?
The model name matters: “Raspberry Pi” alone does not tell you whether Wi-Fi is built in, or which bands it supports. Raspberry Pi’s getting-started connectivity table and hardware documentation distinguish the models.

| Model or family | Built-in Wi-Fi | What that means |
|---|---|---|
| Raspberry Pi 1 Model B, 1 Model B+, and 2 Model B | No | Use Ethernet or a compatible USB Wi-Fi adapter if you need wireless networking. |
| Original Raspberry Pi Zero (not Zero W) | No | For wireless, you need a compatible adapter; account for the Zero’s USB host/OTG arrangement and available power. Ethernet is another option with suitable hardware. |
| Raspberry Pi 3 Model B | Yes, 2.4 GHz | No adapter is needed for a 2.4 GHz network. It has no built-in 5 GHz Wi-Fi. |
| Raspberry Pi 3 Model B+ and newer flagship computers | Yes, dual-band 2.4/5 GHz | Built-in Wi-Fi is ordinarily sufficient for basic wireless access. |
| Raspberry Pi 3 Model A+ | Yes, dual-band 2.4/5 GHz | Wi-Fi is built in despite the board having no Ethernet port. |
| Raspberry Pi Zero W and Zero 2 W | Yes, 2.4 GHz | The W models have built-in Wi-Fi; no adapter is ordinarily needed for 2.4 GHz networking. |
| Raspberry Pi 400, 500, and 500+ | Yes, dual-band 2.4/5 GHz | Built-in Wi-Fi is available. |
| Compute Modules | Varies by model and configuration | Wireless is optional on CM4 and CM5; earlier modules generally lack it. Check the specific module and configuration. |
When is a USB Wi-Fi adapter useful?
Your board has no built-in Wi-Fi
For a Raspberry Pi 1B, 1B+, 2B, or original Zero, a compatible USB Wi-Fi adapter can provide wireless networking. Raspberry Pi’s documentation describes a USB-to-Wi-Fi adapter as an option for devices without built-in Wi-Fi: “Getting started,” Networking.

Your built-in Wi-Fi does not meet a verified requirement
A board with built-in Wi-Fi may still be unsuitable for a particular network—for example, the Raspberry Pi 3B and Zero W models provide 2.4 GHz Wi-Fi, not built-in 5 GHz. Consider an adapter only after confirming that the board’s supported band is the actual limitation and that the adapter works with the board and Raspberry Pi OS.

You are trying to fix a setup problem
A missing or unconfigured wireless connection is not by itself evidence that you need new hardware. Raspberry Pi Imager can configure Wi-Fi while you prepare boot media, and wireless can also be set up later through the desktop or command line. Since Raspberry Pi OS Bookworm, placing wpa_supplicant.conf in the boot folder is no longer the supported setup method. See Raspberry Pi’s current networking and wireless setup instructions.
What to check before choosing an adapter
- Exact board: Confirm the model and variant, especially Zero versus Zero W or Zero 2 W.
- Network band: Match the adapter’s supported band to the Wi-Fi network you need to use. Raspberry Pi notes that some adapters and some Pi models do not support 5 GHz.
- Driver support: Verify compatibility with your board and the Raspberry Pi OS version you run; do not assume every USB wireless adapter works automatically.
- Physical connection: Check whether the board needs a USB host/OTG arrangement, whether a port is available, and whether the setup leaves room for other devices.
- Power: Confirm the adapter and any USB arrangement can be powered reliably by your setup.
- Alternative connection: If available and practical, Ethernet avoids Wi-Fi band and wireless setup requirements.
No particular third-party adapter model is established as compatible here. A specific recommendation would need model-level evidence for drivers, bands, connector arrangement, and power. There is also no basis for assuming an adapter will improve speed or reception over a board’s built-in Wi-Fi; that depends on the hardware and environment.

If built-in Wi-Fi is not showing up
- Confirm the board variant. Check its printed model or order details; an original Zero has no Wi-Fi, while Zero W and Zero 2 W do.
- Check the network band. A 2.4 GHz-only board cannot connect using built-in 5 GHz Wi-Fi.
- Set the WLAN country where applicable. Raspberry Pi says the correct country must be configured before wireless networking is enabled on applicable dual-band devices; it also lets the device select permitted 5 GHz frequencies. Follow the Raspberry Pi wireless setup guidance.
- Use a current setup method. Configure wireless in Raspberry Pi Imager, the desktop, or the command line rather than relying on the removed Bookworm-era boot-folder method.
- Only then consider an adapter. If the board lacks Wi-Fi or a confirmed limitation remains, check the adapter against the compatibility points above.
