Arch Linux user having problems with WN725N v2 TPLINK usb

The wifi USB works fine on my laptop with old Arch Linux, and on my Arch USB (its july version) but it doesn't work. It's detected, but does an endless loop of no networks. I use gnome. Just to clarify this USB worked for many months automatically. I have 2 and both don't work.

Here is output of lsusb

Bus 001 Device 002: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter
Linux kernel is 4.7.6-1-ARCH

uname -a is Linux nameofcomputer 4.7.6-1-ARCH #1 SMP PREEMPT Fri Sep 30 19:28:42 CEST 2016 x86_64 GNU/Linux

I've tried multiple drivers from github and none work. Can someone give a suggestion? Please?

It's detected, but does an endless loop of no networks.

Please always post the actual error output (in code blocks) not some no-information like "it doesn't work".

This is the output

Doing iw dev doesn't show anything, iwconfig works and detects. Trying to do ip link set wlp0s20f0u4 up just keeps it as

3: wlp0s20f0u4: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN mode DORMANT group default qlen 1000
    link/ether 18:a6:f7:09:9d:64 brd ff:ff:ff:ff:ff:ff

It sees the wifi card but it can't search for networks. However, it used to work and on my Arch USB which is 7.1.16 (july first) it works with wifi-menu just fine. Using Arch with wifi-menu, this happens.

Scanning for networks... ioctl[SIOCSIWAP]: Operation not permitted
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument
failed

Can someone provide any suggestions?

Please provide actual output, not your interpretation of what is working and what is not: https://bbs.archlinux.org/viewtopic.php?id=57855

Paste the output of:

ip link set wlp0s20f0u4 up
ip link show wlp0s20f0u4
iw dev wlp0s20f0u4 scan | less

Moving to NC...

First one is
RTNETLINK answers: Operation not permitted

Second one is
3: wlp0s20f0u4: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN mode DORMANT group default qlen 1000
    link/ether 18:a6:f7:09:9d:64 brd ff:ff:ff:ff:ff:ff

Third is command failed: Operation not permitted (-1)
without less but with less it's just lines that begin with ~ and it says END at the end. Now it's just blank lines like











(END)
