The only thing I can think of now is that maybe there is a virus on the hard drive that is so virulent that it cannot be removed any other way than by a piece of software like killdisk. You can download a free copy from lsoft. it can wirpe the free spaces clean or clean the whole disk clean but you will have to reinstall again if you do that or maybe change the hard drive. I had to use it one time because the virus was so virulent it would not allow a reiinstall at all. It was a display adapter virus.

I appreciate your attempts a lot though! It means a lot to me xD I will list everything I own and try my best to describe how its all connected, however it will have to wait until tomorrow. As far as I know when it comes to how its connected: Our modem is connected directly from the outside through a TV Cable. We have a switch next to it connected to it, with a good 5 or so cables, that each goes to their respective rooms. And my computer is, at the moment, connected to the wall in my room.

So for me, its computer > wall > switch > Modem > Outside World.

I'll list what modem and switch we are using tomorrow, as I don't have access to it at this time of day / night.

I've never seen this approach solve a TCP connectivity issue.
TCP (as apposed to Browser issues) is so fundamental that it works OR there's an equipment / configuration failure.

The modem we are using is called "Sagem fast 3890" And was provided by our danish company "Yousee."

Also (Again,) I just now had one of the worst cases of the internet issue. My adapter just turned on and off sporadically like, 20-30+ times, midway through I tried changing to the other adapter, to see if it was a specific adapter issue, but it is not, both of them were spasming out when they were in use. And after about 7-10 minutes, its back to working.

I would like to help you, but at the manufacturer's website for the device the manual nor the emulator is listed for that model number. Also, the language is danish and the chat agent said their technical department did not support that model of the router. I see from what screenshots are available wxp was the os so this must be an older model router. Have you called your ISP? They might change it for you with a newer device.

The problem begin approx 3 or so years ago. And has gradually gotten worse and worse over the years, to the point where its literally stressing me out when I'm gaming. I have tried calling my ISP, and they don't know what's going on, so they cannot help me.

Don't recall, but did you look at temperatures inside your system?

You mention gaming - - is that the ONLY time it fails?

We're all grasping to understand, just as I am sure you are.

I Stand corrected:
As a major player in Broadband, Sagemcom adresses with this DOCSIS 3.1 home gateway, the F@st 3890, a technology breakthrough to enable the ultra broadband experience.

Thanks to the DOCSIS 3.1 technology, cable operators can provide multi-gigabit throughput to their subscribers and enable a new world of ultra-fast services.

Sagemcom integrates this technology breakthrough in the F@st 3890 which can operate simultaneously DOCSIS 3.1 and DOCSIS 3.0 32x8. This new gateway includes the last-gen Wi-Fi 4*4 11ac wave 2 for 5GHz, 4*4 11n for 2.4GHz, and implements MU-MIMO superior Wireless.

Then we have a router and not a modem. As for it happening only when gaming, no, it can happen at any point, while watching movies, while doing nothing at all.

My biggest fear is that it really is just the motherboard having been worn down. The computer was built as a beast, and still holds up to this date in regards to graphics and performance, but everything else haven't fixed this issue.

I fear you have the wrong WiFi driver. As "others are using it w/o problems", that says the fast 3890 is not suspect.

I'm using the absolute latest possible drivers I could find for my NIC too though. But given that two different network cards displays the exact same issues, at the exact same time, I fear it is not a driver issue either.

The only thing I can think of at this point is to ask the ISP to change the device. You said they couldn't help you and the chat tech support agent I talked with said that they did not support this model anymore. You said the problem started about 3 years ago, that's a long time and like I said all the screenshots to configure the router showed and xp screen. There's something rotten in Denmark.

Its just weird because yes, the problems began about 3 years ago, but the router were given to us about one or two months ago. If they don't support this model anymore, its just really weird they'd send it to us in the first place. I suppose it is something to try though, so I'll look into it.

Fair enough, the old modem did have the same problem though. But I'll try and see if I can get them to send us a newer, and still supported type.

So, I might be on to something here. I believe the issue might be that my computer is overheating. I found out just now that my fans are extremely unstable, which results in the heat getting to excessive heights, and it seems to match with the DC timings

You might have to replace them if they are unstable, but I would give them a good cleaning first and the heatsink too. The thermal glue between the processor and the heatsink may need changing as well.

I'll look into that. However I continued monitoring the heat with the internet, and it continue to fail even when heat was around 60c so its not that either.
