laptop wifi can not link to access point

Ok, I've been working on this problem for days now and have reached a brickwall so here I am. The problem that I'm having is that the wifi card on my old Toshiba Satellite L305D is seen, and seems to work fine, but I can't link to the AP using iw.

Currently, in this setup, I opened the AP so that I was sure that it was not a wpa issue. I'm using the RTL8187B Realtek Adapter.

[root@laptop /]$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
    link/ether 00:1e:33:fe:6c:d0 brd ff:ff:ff:ff:ff:ff
3: wlp0s18f2u6: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DORMANT group default qlen 1000
    link/ether 70:1a:04:54:11:a4 brd ff:ff:ff:ff:ff:ff

So it looks like arch sees the wifi card and it's up

I can scan it.

[root@laptop /]# iw dev wlp0s18f2u6 scan

It looks like it sees my AP so I'll try to link it now.

[root@laptop /]# iw dev wlp0s18f2u6 link
Not connected.

Ok, so I'll try to connect

[root@laptop /]# iw dev wlp0s18f2u6 connect -w DNET
wlp0s18f2u6 (phy #0): failed to connect to 00:1d:7e:3a:74:a2, status: 1: Unspecified failure

I have another laptop connected to this same AP and it works fine, so I know that it's not in the router. This laptop was working fine before I whipped out the old OS and put Arch on so I know that it shouldn't be an hardware issue. I tried both wifi-menu (which always seems to work everywhere else) and wicd but neither worked. Not really sure where I should go from here.
