All the wireless networks are showing twice and suddenly the speed is very decreased. It was working fine few hours ago.
I remember one thing that I installed aircrack-ng few days ago but the wlan was working fine. Suddenly it's not connecting to any wifi.
U use two, wlan1 and wlp450, kill one of them 
sry for a noobie question can u give me a command for it.
I searched on google but u know noobies grt more and more confused when read commands for another distro:joy:
First check
nmcli
nmcli device show
Second delete the right one 
nmcli connection delete id <connection name>
This sounds like a symptom of incorrectly installed wifi driver.
Use USB Android phone tethering for an internet connection.
Please post as text (no pics):
inxi -Fxxxza
lspci
lsusb
lsmod | sort
There are two outputs as below.
nmcli device show
GENERAL.DEVICE: wlp4s0
GENERAL.TYPE: wifi
GENERAL.STATE: 100 (connected)
GENERAL.CONNECTION: Redmi
GENERAL.CON-PATH: /org/freedesktop/NetworkManager/ActiveConnection/1
And
GENERAL.DEVICE: wlan0
GENERAL.TYPE: wifi
GENERAL.MTU: 1500
GENERAL.STATE: 30 (disconnected)
GENERAL.CONNECTION: --
GENERAL.CON-PATH: --
My command should be:
nmcli connection delete id wlan0 ??
tbg is the wifi expert
follow him, please
Okey sure!!
Currenlty i am connected to Redmi(wlp4s0) automatically.
And that Redmi(wlan0) is disconnected

Have you read installation and usage instructions about this application before installing?
You installed a system utility, that may break your system, if it is not compatible with Arch systems.
At least, check archwiki for relevant info and arch forum for others with problems.
It seems the systemd way of handling network names is interfered with something, that maybe this utility.
That’s all that I know.
Oops, My bad. 
So, just out of curiosity, are you dual booting windows?
Some suggestions to follow in the order they are listed:
Delete all WiFi connection profiles in network manager, then recreate them.
Reboot both your router and computer.
Disable MAC address randomization in network manager.
Reset your router to the default factory configuration.
Lock your Wifi through your router via its MAC address. This is usually referred to as MAC address association in most router setup utilities.
If none of the above work, then I would recommend returning to the old network naming conventions.
You can do this by adding the following kernel boot parameter to grub:
net.ifnames=0
The following command will automatically add the above kernel boot parameter to /etc/default/grub:
sudo cp /etc/default/grub /etc/default/grub.bak && sudo sed '/^GRUB_CMDLINE_LINUX_DEFAULT=/s/"$/ net.ifnames=0 "/g' -i /etc/default/grub && sudo update-grub
It will take a little while to regenerate grub.
When the process is finished reboot.
Be sure to post any errors if they occur.
Still no success then test some alternate kernels. The ones I would suggest starting with are the LTS kernels, and linux-hardened kernel.
