Virtually all professional WAPs (what are on topic on this site) have 1 Gbps ethernet ports.
A WAP is a translating bridge, it translates from ethernet to Wi-Fi and back. You need to understand that you have two different, independently-developed technologies being bridged. One technology, ethernet, has standards for different speeds (10 Mbps, 100 Mbps, 1000 Mbps, and 10,000 Mbps) on UTP. Each bump in speed costs more, and it took some years between bumps in speed. On the other hand, Wi-Fi was developed for its medium (radio), and it has multiple standards, each with its own maximum theoretical speed. Because of real-world obstacles, it is unlikely that you can get anywhere near the theoretical maximum speed on a WAP. To bridge these disparate technologies, you need to use what each technology offers and balance the price/performance ratio, otherwise your product won't sell.
