Problem with Network Manager

On my Old laptop with Ubuntu 16.04. I can not make any connection. Last time I have used this laptop was 3 Month ago and everything was ok.
I think it’s a Network Manager. I have tried to restart, start Network Manager service. But it didn’t help.
But I don’t have any idea what to do.
Please Help me.

are you trying to make a wired or wifi connection?

Both are not functioning.

do they show up when you:
sudo lshw -C network

I made a mistake. I didn’t know that LAN port 4 don’t functioning.
The problem is only that WiFi on laptop is Disabled.

sudo lshw -C network
