So I have a persistent live OS on my USB drive and am using an ISO of fedora 20 with the rpm-fusion repository and some software updates. However, when I boot this OS no networks to connect to are displayed. My computer's specs are high (including the network card), but no networks show themselves. I find this really odd because when I download a new OS it can usually connect to a network no problem (provided I provide a password), so it can't be a driver problem right? I can't even find the wireless network interface when I type in ifconfig into the terminal.

Try ip link instead. Also check man iw and man iwconfig. For now, those tools are more compatible with the current framework of device communication in your system. There is also networkctl for information on network interface.

After verifying a working interface, make NetworkManager work right, or disable nm and use wpa_supplicant directly. Archlinux wiki has very detailed documentation on this topic.

This doesn't really seem to help me. The issue is that my system doesnt have a wireless network interface. The output of the command iwconfig is "enp1s0f0 no wireless extensions lo no wireless extensions"

Means you are missing a module. lspci -v|grep -E -A5 -i "network|wi-fi" could help you determine if a module is loaded. Maybe there is a simpler way, like maybe going through lsmod | less.

Here is the output of lspci -v|grep -E -A5 -i "network|wi-fi" 02:00.0 Network controller: Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02) Subsystem: Apple Inc. AirPort Extreme Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at a0600000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied=""> Kernel driver in use: bcma-pci-bridge

So, you do have a module loaded. Did you turn it off at some previous time? With soft-kill?

No I have never done that. The part "Capabilities: <access denied="">" concerns me the most. That being said, I am using a school-issued computer; they are root on the hard drive's OS and own this computer until I graduate. However, I have contacted them and they said I can fix this issue without them if I can; If I can't then I can contact them for help. So how do I gain permission to use this module? Maybe I can reload the module? (if that even is the issue).
