I have gigabit connection. One morning I turned on my computer and noticed youtube buffering very slow. It was working perfectly the night before. Noticed stuff connected to wifi started to slow down, so I contacted costumer support, got a new modem/router sent to me.
Wifi connections are working just fine but when I connected my desktop to ethernet, it still ran slow. I haven't downloaded any new program so I dont think its a program thats messing with connection. I don't think its the main cable because when I connect it directly to my desktop, it runs perfectly but as soon as i plug it back into the wifi, my desktop slows down. I have tried connecting my laptop to ethernet and it seems to work just fine.
When I turn on a VPN, my internet seems to work perfectly. Anyone have ideas what could be happening? If need more info I am will provide.
