My laptop connects to other wifi routers and everything works, but if I connect to my home router it doesn’t work. I tried to connect to router by cable that goes through router, still doesn’t work. If I directly connect the internet to the computer without a router, it works. If I connect to wifi with my phone and share wifi to laptop it works.
If I boot from usb wifi works.
Obviously this is an issue with your router.
We can’t help you troubleshoot your router … 
but router doesn’t work only on my laptop, with other devices it works
Since your Manjaro Linux system work as expected with other routers - it is obviously your home router which does not accept your Manjaro Linux system.
Why it is so? I have no idea and it is impossible to guess.

I booted manjaro from usb and wifi worked, so I think problem is my settings
next step: create another user, log in as this new (test)-user. does it work ? in this case it would be something with your personal config files of the origin user, otherwise it’s something related to general settings.
I created new user and tried, it doesn’t work
did you edit any config files like /etc/resolv.conf or others in the past ? are you using any vpn or other things that you still not posted here ?
No, i didn’t change anything
Possible helpful info you can provide
Output (as text - not screenshot) from
cat /etc/resolv.conf
and
nmcli -t device show
okay take a live-iso and boot to the live system. connect to the internet with this iso. does it work ?
Yes it works
You should always paste terminal output inside a code fence like this
``` output from cat /etc/resolv.conf ```
Thus you would have been able to paste the complete outpu but a pastebin is equally good.
You have a lot of containers running on bridged interfaces …
I see your primary wlan interface
GENERAL.DEVICE:wlp0s20f3
GENERAL.TYPE:wifi
GENERAL.HWADDR:52:51:B6:59:01:4C
GENERAL.MTU:1500
GENERAL.STATE:100 (connected)
GENERAL.CONNECTION:Torro
GENERAL.CON-PATH:/org/freedesktop/NetworkManager/ActiveConnection/37
IP4.ADDRESS[1]:192.168.0.107/24
IP4.GATEWAY:192.168.0.1
IP4.ROUTE[1]:dst = 192.168.0.0/24, nh = 0.0.0.0, mt = 600
IP4.ROUTE[2]:dst = 0.0.0.0/0, nh = 192.168.0.1, mt = 20600
IP4.DNS[1]:192.168.0.1
IP6.ADDRESS[1]:fe80::3ad4:c565:ae41:b3bd/64
IP6.GATEWAY:
IP6.ROUTE[1]:dst = fe80::/64, nh = ::, mt = 1024
Then you have a bridge using the same ip range but with a different subnet
GENERAL.DEVICE:br-b5a6206d4f70
GENERAL.TYPE:bridge
GENERAL.HWADDR:02:42:2F:C6:1A:EB
GENERAL.MTU:1500
GENERAL.STATE:100 (connected (externally))
GENERAL.CONNECTION:br-b5a6206d4f70
GENERAL.CON-PATH:/org/freedesktop/NetworkManager/ActiveConnection/2
IP4.ADDRESS[1]:192.168.0.1/20
IP4.GATEWAY:
IP4.ROUTE[1]:dst = 192.168.0.0/20, nh = 0.0.0.0, mt = 0
IP6.GATEWAY:
And that could be your problem
One cannot and should not advise what to do or not do to solve this - it is simply not possible when one does not know the purpose of everything else - you on the other hand is supposed to know everything about this.

if you didn’t all the editing of the config file then who did it ? in this case i recommend that you ask the person who did all the settings !
btw. this is another topic where users claim they don’t know what happened, they did no changes and in the end we get a mess presented that the user expects to get solved by us. sorry but if you didn’t edited these configs, what i really trust, then ask the guy who did it not to get in trouble with him because “we” supposed to do so.
how can I remove that bridge? I really do not understand networks. I use docker for web development and it created containers
I have no idea - you are on your own with that.
One possible avenue could be to remove containers you don’t actually use.
ok, thanks
