A few months ago my computer started to have issues with internet, the router works fine because my phone runs fine on it, the internet is fast because I run another computer on the same router with no problems, I have tried multiple Ethernet cables. But I have really slow internet, steam thinks I’m offline, and webpages take a minute or to to load. I cleaned it and it made it better for about a week and now it’s slow again. Any help would be very appreciated
