AdriftAtlas is spot on. This adapter has that better chipset: https://www.amazon.com/gp/aw/d/B084L4JL9K. Sadly it has the cable attached too.

This topic came up about nine months ago, and I answered in detail then: https://www.reddit.com/r/mac/comments/wf8fbe/comment/iitv5cs/?context=3

The adapter I bought as a result of the (hours of) research I did, and have been using ever since, is the Plugable 2.5G USB-C/USB-A to Ethernet adapter: https://www.amazon.com/gp/product/B084L4JL9K/

This device is a bit more expensive, but uses a newer Realtek 8156 chipset, which has long worked with the native driver in macOS. It's been rock solid in use with my MacBook Pro 13" M1.

However, as /u/poopmagic (who was also in that thread, hello again!) has indicated in a couple comments of this thread, it appears that macOS 13 ("Ventura") includes improved drivers, such that the much more common Realtek 8153 chipset now runs on the native driver.

That's great news for a lot of people, because the older chipset was used in a lot of other products—including the Belkin USB-C to Ethernet adapter sold by Apple! (Perhaps that was the motivation to support the older chipset.)
