I've been having some trouble recently, my ethernet has gotten really slow every other day for the whole day for no reason. I used to get 120 mbp/s for download speed and 40 mbp/s for upload speed, now currently I'm getting a max of 20 mbp/s for download speed and a max of 12 mbp/s for upload speed. It's starting to piss me off. My internet provider is cox which I would love to change however I'm 16(almost 17) so I don't really have control over the provider. I hear from other people that cox is a complete shit hole.
BTW my ping has stayed relatively the same 10-20. My ethernet can take a total of 1 gigabyte, so I know my ethernet isn't limiting it. I haven't changed any hardware/software settings. Nor is my PC limiting it because it didn't really have a problem before. So, instead of getting a new provider(Because it's not an option). What can I do about it?
