Should I plug my Ethernet into router or modem?

Generally, if you have both a router and a modem, you should plug your Ethernet cable into the router.
Here are a few reasons why:
The modem connects your home to the internet service provider (ISP) and usually only has one Ethernet port. If you plug your Ethernet cable into the modem, you will only be able to connect one device to the internet.
The router connects multiple devices to the internet and provides additional features such as Wi-Fi connectivity, network security, and advanced configuration options. If you plug your Ethernet cable into the router, you can connect multiple devices to the internet and take advantage of these features.
If you have a modem/router combo, you may not need to plug your Ethernet cable into a separate router.
In summary, if you have a separate router and modem, plug your Ethernet cable into the router. If you have a modem/router combo, you may not need to plug your Ethernet cable into a separate router.

Is an Ethernet cable faster than Wi-Fi?

In general, an Ethernet cable connection can be faster and more reliable than a Wi-Fi connection. This is because Ethernet cables have higher bandwidth and are not subject to interference or signal attenuation like Wi-Fi signals are.
Ethernet cables can provide speeds of up to 10 Gbps, depending on the type of cable and hardware used. In contrast, Wi-Fi speeds are typically slower, with the maximum theoretical speed of Wi-Fi 6 (802.11ax) being 9.6 Gbps, but real-world speeds are usually much slower due to interference, distance from the router, and other factors.
However, it's important to note that the actual speed you will experience will depend on various factors, such as the quality of your Ethernet cable, the network infrastructure, and the devices you're using. Additionally, Wi-Fi can be more convenient as it allows for wireless connections, whereas Ethernet cables require physical connections.
