i dont know how, but after i switched from zorinOS to fedora (nobara), my wifi got REALLY slow.
how it works: usually, my wifi gets to 0B/s for no reason, or it just get slow for no reason, before anyone says that my wifi is just bad, i want to say that it works well on any other device on my house, including cellphone, etc.
i already tried disabling wifi powersave, it didnt work.
my wifi driver is a realtek RTL8821CE.
