Hi, just this week my wifi card has started to give horrible internet speeds. for reference, I am using the xfinity trapizoidal prism router and a fast computer, with 200mbps download and 6mbps upload. I went from getting 180 download + 5 upload to now only getting 60 download + 1 upload. it was a sudden change, and none of my hardware changed when this happened. is the card dying/dead, or is it a fixable issue. if it is dying, is this covered in the warranty? at this point, any help would be appreciated. also, my phone (iphone se 2020) gets perfect wifi when held in the same area as my wifi card.
