I’ll break my comment into a few sections but anything in quotes is a tech term that you should look up if you’re interested in learning.
TL:DR: you’re looking for Home Networking Specialists or Low Voltage Contractor (or a subreddit that is close enough)
Wireless: If your router is capable of dual-band broadcasting use the 2.4GHz network.
Why: 2.4GHz is a longer wavelength and can penetrate walls a bit better and travels farther. 5GHz is a shorter wavelength loses distance in favor of higher speeds but sucks through walls.
Note: 5GHz =/= “5G Cellular”, completely different stuff.
Wired: You will get a lot of questions here about your setup. You mention that you’re plugged into the wall but there may be a few things between you and your router that can affect speeds such as a “dumb switch” or a “hub”.
Are you in a apartment complex or a single home as that may change what you’re able to look into yourself before having to get permission from someone.
What is your “modem” wired into? Satellite, cable or fiber?
Once you answer these questions folks may have a better idea on how to help you.

Edit: changed my first sentence as I went more than two sections
