Security type WPA2 Personal. Modem / Router is CenturyLink C4000XG. I had Ubuntu installed previously, same issue. I would prefer to get this chip working rather than use a USB wifi adapter (I have one but had no luck with it either, I think the issue is something else, possibly because this modem is rarely used for Linux because CenturyLink is like "lol linux wat").
4 machines (mac, mac, windows, android) can connect to this wifi with no issues. I can even take one of the USB adapters and plug it in to the windows machine and use the USB to connect to the wifi. The linux machine is currently connected to the internet via a CAT5 cable that is running across my floor to the garage. Sticking with the CAT5 means crawling around in the crawlspace and drilling through concrete. So I'd really prefer to get the wireless working.

This is already getting long, so the rest of my troubleshooting is in this pastebin: https://pastebin.com/LphnG3gN
What next? Am I missing something?
