randomly get bad internet only on computer

[soar]

Once a month or so just my pc gets awful internet. And it's only my pc everything else works fine in the house. It still connects but it's much worse. Videos lag on 144p. I get 400 ping on online games. And download speeds at like 100kbs. The websites still load quickly and normally though. This problem will probably go away within like 3 days if I wait it out. But I'm trying to figure out how to fix it or at least why it happens

What speeds are you paying for through your ISP?

Are you using wireless?

What is the model of your router?

I'd contact your ISP

I think is your ISP you can also try to uninstall your network card and install it again. When it happens try to do a speed test from 2 devices. To see if rly is just your pc. What SO are you using? Maybe you have Windows 10 and P2P updates are enable. Monitor your network from "Task Manager>Resource Monitor" and see what's happening. Analyse your software maybe one of them have a scheduled connection to network. We need more data to help you.

I think it might be the audio cables. Last time this happped like a month ago my bro connected speakers. And literally right after the internet lagged. I took them out and a day later the internet was fine. But I didn't think it was the speakers fault. But yesterday he did the same thing as before and put in the speakers. Now it lagged again right after. Sounds dumb but I'm starting to think the speakers are actually causing the problem. I haven't tried to take them out yet tho so I mght be wrong
