Networking problem

So my wifi wont work, it said something along the lines with rf-killer not sure now not on pc. Anyways i always have issues with wpa_supplicant thing and das why i opt for networkmanager, networkmanager always works fine for me on linux distros but this os doesnt seem to come with one so, i dont got access to ethernet or something so that isnt an option, i attempted to download the files for instilling the network manager package on usb and then trying to install it that way but it was missing like 8 other packages which network manager seems to rely on so
