Hi,

Don't know if it helps, but I wrote down what I did yesterday evening with my RPI5 16GB.

Purchasing an AX88772-based adapter

Many third-party USB-to-Ethernet adapters available on Amazon or Newegg use this chipset and specifically list compatibility with Nintendo consoles.
The compatibility is "driverless" for these Nintendo devices, meaning you just plug it in and it works automatically.
Be mindful of the product specifications, as some manufacturers also sell adapters with different chipsets (like the AX88179 for gigabit speeds), which may not be fully compatible with older Wii or Wii U consoles.

The HORI Ethernet LAN adapter for the Nintendo Switch does not use an ASIX AX8872A chipset

. Instead, it uses the older ASIX AX88772 chipset, which limits its connection speed.

Chipset differences and speed limitations

ASIX AX88772: This chipset, used in the HORI adapter and older Wii/Wii U adapters, is limited to a speed of 10/100 Mbps (Fast Ethernet).
ASIX AX88772 vs. ASIX AX8872A: An online customer review from May 2025 highlights that the HORI adapter works with the Nintendo Switch, but its AX88772 chipset restricts its speed to 10/100 Mbps Fast Ethernet.
Nintendo Switch Dock Speed: The HORI adapter's speed is a key point of discussion for users. A 2021 Reddit post indicates that recent batches of the HORI adapter were shipping with a USB 2.0 (100 Mbps) chipset instead of a USB 3.0 (1 Gbps) version. A HORI support representative confirmed that the standard Switch dock's USB ports only operate at USB 2.0 speeds, limiting even a faster gigabit adapter to 480 Mbps.
Alternative adapters: Some users have opted for generic adapters with the ASIX AX88179 or AX88772 chipset, which, depending on the model, can offer faster connections. For the standard Switch, these adapters will be limited by the dock's USB 2.0 speeds, but they may offer an upgrade over the HORI adapter.

What this means for Nintendo Switch users

For most gamers, an adapter with a 10/100 Mbps speed is sufficient for a stable, lag-free online gaming experience. Internet speed tests on the Switch may not accurately reflect real-world performance during online play.

Where to buy

If you are looking for an official, Nintendo-licensed adapter, the HORI Wired Internet LAN Adapter is still a popular and reliable choice for the Nintendo Switch.

2. Update to the latest version (recommended)
Before starting the update, make sure raspberry pi 5 is connected to the Internet;
You can refer to the official document: update firmware or following steps:

Update via command:
sudo apt update
sudo apt upgrade -y
sudo rpi-eeprom-update
If a firmware update is available you will be prompted to install it and your Raspberry Pi will reboot. More information about updating the firmware on your Raspberry Pi is available in the official documentation.

Use tool raspi-config to update
sudo raspi-config
Then select 6 Advanced Opitions => A5 Bootloader Version => E1 Latest, answere Yes）
Then reboot and the firmware will be updated (requires Internet access).
