i have very bad internet even iam using the fast internet it's always like 0.01kb to 6 kB the fastest it's the same like using slow connection bruh (it's not worth it to use this card) my issue is: it's not cheap it's useless because the fast one and slow internet it's the same I can't see any difference just use the different card bruh this card is so laggy so don't use this card
