Internet suddenly extremely slow

[NunoLava1998]

Hello! Since the last few days, my computer at sporadic times connects to the internet extremely slowly (sometimes for hours straight, when it does work it's normally only for a few mins). I've seen it get to a 0.00 on the Ookla Speedtest. For some reason, it always happens like this:

1. Goes to an unusually low speed as a peak (around 7 to 10 mbps on the Speedtest)
2. Slows down extremely gradually (Normally drops below 1.00 mbps on the Speedtest)
3. Slows down over a matter of minutes (Normally drops below 0.30 mbps on the Speedtest)

My average speed is about 30-50 mbps on the Speedtest. How would i fix this?

 

This is also a software issue; I've tried with my installation Ubuntu, my other backup installation of Windows, and they run fine. The other people in my network have good results. I can't seem to determine the problem. Does anyone know what might be causing it? Specs:

 

OS: Windows 10 dualbooted with Ubuntu + Windows 10 Windows To Go USB (my backup installation of Windows)

CPU: Intel Haswell i3 4160

RAM: Kingston 8GB

GPU: Nvidia GTX950

HDD: Some WD 1TB

 

I had the Kaspersky Internet Security, but i uninstalled it (didn't restart yet though). No effect on anything. Not a browser thing (slow on games too). Anyone got suggestions?

I'm just guessing here but are you hooked up with Suddenlink?

Hi @NunoLava1998

 

Are you on wireless?

What about your phone? what are you getting on the wifi?

Have you tried another Ethernet cable if connected through cable?
