Yes, most 5G gateways do come with Ethernet ports. Here's a more detailed explanation:

1. Typical configuration: 

Many 5G gateways include at least one Ethernet port, often multiple ports.

2. Purpose: 

These ports allow you to connect devices directly to the gateway using an Ethernet cable, providing a wired connection option alongside the wireless 5G connectivity.

3. Advantages: 

Wired connections via Ethernet can offer more stable and potentially faster speeds for devices that support it, which can be beneficial for things like gaming or large file transfers.

4. Variation between models: 

The number and type of Ethernet ports can vary depending on the specific model and manufacturer of the 5G gateway.

5. Examples: 

Some gateways might have 1-4 Gigabit Ethernet ports, while more advanced models could include 2.5GbE or even 10GbE ports.

6. Flexibility: 

Having Ethernet ports provides users with more options for connecting devices, especially those that don't have built-in Wi-Fi capabilities.

It's always best to check the specifications of the particular 5G gateway you're interested in to confirm the exact number and type of Ethernet ports it offers.
