My pc's internet speeds have been slowly degrading over the past week. At first it was just the up down speeds over wifi. Then I plugged it into my ethernet, and my ping was amazing, but my up down speeds seemed to be just 4Mbps. I recently got a new higher wattage psu and was wondering if that might be an issue? But the up down speeds were getting worse even before then. I have an old 2017 Alienware aurora r7 that I have been upgrading consistently, but the motherboard has remained the same. I recently reinstalled windows, have checked that it is using 5ghz connection, and is not being limited in the settings.
