So I just started duel booting with ubuntu and windows, I installed linux and everything works, except i can't connect to my wireless adapter, I have internet on windows and it works fine, but not on ubuntu, I can switch between them and it all works, I can also download drivers from windows for linux on a usb, then switch to linux to install them, but I don't know what the problem is, and what I need to do to fix the problem. Any help would be appreciated

A couple things about my system:
both windows and ubuntu are booting in bios mode
windows device manager shows my adapter as: Realtek 8812BU Wireless LAN 802.11ac USB NIC
running windows 10 and ubuntu 20.04.2.0
on ubuntu, i'm using kernel 5.8.0-43-generic

when I run the command lspci:
