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

I’ve worked at an ISP NOC for several years where part of my job was supporting various wired and wireless environments that have Internet access delivered in a variety of mediums.

Long story short, if your Verizon service is a cellular home plan (since it’s 300mbps and Verizon offers these plans it sounds like it could be) then you’re gonna feel it over gaming, especially especially with wireless. Your best experience will be wired, assuming the wires aren’t damaged or misterminated or CCA.

With wired, your LAN experience will be ideal from your computer until the router. The router, however, deals with two sides of the equation. Your local network and then the internet. It has to communicate outside of your home. If that’s happening over a cellular connection then you’re just going to see latency and packet loss and there’s nothing to do about it unless you can change physics.

Assuming you’re cellular, the fix is to move to a wired medium (even fixed wireless would be a step up though). Wired internet such as fiber or coaxial cable is far less susceptible to interference and is capable of moving data quicker and in a more stable method. But it tends to be more expensive and requires more “visible” maintenance on the ISP’s end which can be frustrating for the customer.

Semantics but it’s probably more accurate to say you have Verizon internet up to 300 Mbps. You could argue it’s ~WiFi if the provided service is all wireless (e.g., T-Mobile home internet). Too many people say WiFi when they mean internet.

To be fair, most home users are using WiFi, so it’s somewhat understandable. In the future, we may well see the words converge or even “wired WiFi”. I’ll get off my soap box now.

Call you local computer repairman. That was me for over 20 years in a medium-size town.

There are lots of places to look for trouble - the cabling needs to be tested, your ethernet adapter may just need a new driver… so many possibilities.

Professionals specialize in troubleshooting these issues. Troubleshooting is just using LOGICAL steps to narrow down to the cause of a problem.

Have you tried hooking up your PS to the other family members connection? I would think that if you’re fine on their connection but screwy on your wired connection then perhaps an issue with your wiring? Is it an old place and maybe an old cable? Do you know what kind of cable? You could try getting a length of cable and see if thats better. From a customer service pov you should not have to be restarting your router all the time. They should be able to figure out whats going on.

Haha, I read my Wife is trash…🙈
