TL-WN823N cannot bring interface up [SOLVED]

Hello everyone!

Yesterday I finish installing ArchLinux and everything works great, but I do not know how up this usb wireless.
I had tried this but does not work:

sudo ip link set sudo ip link set enp0s26ulu4 up
Cannot find device "enp0s26ulu4"

Output of ip addr:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 60:eb:69:cc:4c:07 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.38/24 brd 192.168.1.255 scope global enp3s0
       valid_lft forever preferred_lft forever
    inet6 fe80::62eb:69ff:fecc:4c07/64 scope link
       valid_lft forever preferred_lft forever
3: wlp2s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether e0:b9:a5:11:d9:0a brd ff:ff:ff:ff:ff:ff
5: enp0s26u1u4: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether e8:de:27:15:33:af brd ff:ff:ff:ff:ff:ff

The device driver seems loaded because dmesg output:

[ 1082.980779] usb 1-1.4: USB disconnect, device number 3
[ 2091.139644] usb 1-1.4: new high-speed USB device number 4 using ehci-pci
[ 2091.390357] rtl8192cu 1-1.4:1.0 enp0s26u1u4: renamed from wlan0

By the way, I'm using current Arch kernel version, 4.0.7-2-ARCH.

Can you tell me what I am doing wrong?
Thanks.

That's a 1 (number one) between the two u's, not a l (letter l).

Wow, it's my fault, I mistake an 'l' with the '1'! Thank you very much!
