i was checking my Mbps on my brand new installation of Fedora 40 and i noticed that from 600mbps in download i got down to 20mbps. What should i do to improve the internet connectivity? If you want more infos you can ask me 
(i’m new to the Linux community but i’m pretty sure this probably is normal for this)
