I have an i7-8700K and an ASUS TUF Z370-PLUS GAMING without built-in Wi-Fi. Is a USB adapter a good option, or should I replace the motherboard? Are there other options worth considering?
Should I add a Wi-Fi adapter or replace my motherboard?

I would add a PCIe Wi-Fi card rather than replace a working motherboard. It goes in a spare PCIe slot and usually comes with external antennas. Check that the slot is accessible and not blocked by your graphics card before ordering.
Cards based on the Intel AX210 are one option to look at. Check driver support for your operating system, and if you want Bluetooth too, check whether the card needs a connection to an internal USB header.

A USB adapter is the easiest route if you don't want to open the case. Plug it in, install any required driver, and you're set. Some have external antennas, which may help if reception is weak.
USB adapters vary in quality, though. A small dongle tucked behind a metal case might not get the best signal, so placement matters. Check that the adapter supports your operating system before buying.

Replacing the motherboard just for Wi-Fi seems like a lot of work and expense. You would need a board compatible with your CPU, and you'd have to move the components over. An adapter adds the feature without that whole rebuild.

If Bluetooth matters too, check for it when choosing an adapter. A separate Wi-Fi adapter won't necessarily add Bluetooth.

First check what your router supports. You don't have to buy the fanciest adapter if the rest of your network can't use its features. Also, if a cable is practical, Ethernet is worth considering for a stable connection. Otherwise, a decent Wi-Fi adapter is a reasonable choice.

That sounds like a much simpler upgrade. I'll check the slot space and look at AX210 cards.
