can't connect to any WiFi at the most unfortunate point of time

Hi, on my phone now. Brought my laptop to hospital but all of a sudden can't connect to a single wifi. First of all it couldn't find the hospital WiFi so I looked up WiFi radar in the docs - was clueless and still am. I sudoku vim'd instead of visudo-ing /etc/bookmarks. Before I realized I didn't even have wifi-radar installed.

And now I for some reason can't connect to a single network - tried sharing the network on my phone - because it NEVER asks for password but instead just says

Jib for nettle@wlp2s0\x2dhmndata.service failed. See 'systemctl status netctl@wlp2s0\x2dhmndata.service' and 'journalctl -xn' for details.

I am about to flip out.... How do I connect to wifi? Always worked before now!!!!!!!

Re: can't connect to any WiFi at the most unfortunate point of time

Well, let us look at the very basics.

What are the outputs of:
rfkill list
ip link
and of
sudo iw wlp2s0 scan

Not soft blocked, not hard blocked.

ip link:
[...]
3. wlp2s0: <NO-CARRIER, BROADCAST, MULTICAST, UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 100
link/ether [row of hex nums]

I don't have iw installed

There is a lot of output and since I don't have any connection on my laptop to upload it, what do I look for?

Re: can't connect to any WiFi at the most unfortunate point of time

I dunno, how about the name of a network to which you may want to attach?

Pare it down some like this:

ewaller$@$odin ~ 1006 %sudo iwlist scan | grep SSID
lo        Interface doesn't support scanning.

enp3s0    Interface doesn't support scanning.

                    ESSID:"Woodlyn"
                    ESSID:"Merlin"
                    ESSID:"2WIRE883"
                    ESSID:"jands"
                    ESSID:"mcfab"
ewaller$@$odin ~ 1007 %

I can see five networks right now.

Re: can't connect to any WiFi at the most unfortunate point of time

I am on my laptop now and I got on wifi for some reason now.. Rebooted 20 times yesterday. Well now I can post logs. I don't know if the problem will cease.
sudo iwlist scan: http://sprunge.us/FFjU

I also saw some errors in the boot process regarding usb; how do I find this?
