My wifi card is the one included in the x570 wifi plus. Its an intel ac620 with an asus 2t2r antenna. It used to get 50 mpbs down while my other devices were operating at slower speeds than it. Now all of a sudden it cant exceed 2-6 down while my others are at 20-80 down. I've reset my network settings and even decided to reset my pc yesterday. What should I do now?
