Yea I never thought about downloads causing connection issues, but I almost never download while gaming and i still have connection issues. I just did it to test it out, but didn’t really think about it. No one in my house uses the internet for more than just browsing, streaming Netflix, and gaming. So it’s nothing too heavy duty that i think should be causing these issues.You are going to have to buy a modem and a router.
Before you chase down this path really think about what you are doing. You said
"Also i've tried downloading games on my PS5 while playing on my PC and there is big spikes when doing so"
Of course this is going to cause problems the download will attempt to use 100% of the connection. A much simpler solution is going to be to set the maximum download rate in the ps5 to something lower so it does not max out the connection.
You have a huge internet connection and should not have trouble running any mix of applications. Download pretty much the only thing that can kill it.
I would see if there are simpler solutions like trying to find what other traffic is causing the problem and try to fix the traffic rather than looking for magic routers.
The largest issue is with a really fast connection like you have you need a massive router cpu to keep up when running any form of traffic shaping. Lets say you decide to use the merlin firmware and the fancy traffic shaping it has. Even with the fastest router you can get you are going to give up 100-200mbps of your 500mbps connection. Is it worth giving up that much bandwidth to do this. The only things that can really keep up with a 500mbps internet connection is a small pc running as a router.
The QoS is normally only need on smaller connections say 50mbps-100mbps. When you have a large connection like yours if you are running it at 100% especially if it happens for long periods of time you have something very wrong with the traffic in your house. You see this when you have teens who run torrents constantly. Note the fancy things like FQ-codel shaping will not stop torrents from causing issues you must use a much more brute force approach to that.
I don’t know if my ISP is giving me a good enough router that can handle these speeds. Or is there even one that can handle these speeds without issues?
Before I had a plan of 200-300mbps with limit of 1000GB of data and had no issues with connection, but during Covid we were exceeding 1000GB and were getting charged for that. So, we decided to go to the 500mbps 2000GB. Now when we made this switch our router never got replaced. So, maybe it should have? However I have called my ISP and told them the problems im having and they said there is nothing they can do. They said that since me speeds are good then the problem might be on my part, but I have a new PC and my brothers PC also has the same issues. I am paying $12.95 a month for the router and im starting to think that’s the problem because I’ve tried just about everything I can think of on my end. Im willing to spend some money on a good router considering I’ve been renting this router for close to 5 years now. However, what’s do you meant by a router and a modem? Are they 2 different things? Will I have to get both? I honestly don’t know much about router or modems so I don’t know which ones are good. Also will my ISP support a router that’s not from them directly? Sorry for all the questions.
