Wireless networks are not being seen by network manager

Summary: In this article I am going to show you the solution of the problem: wireless networks are not being seen by network manager even if wireless card drivers are installed.

Yesterday, I reinstalled Linux 1.14 Nadia in my pc. After that I installed my wireless card driver which is Broadcom Corporation BCM4312. I learned its name and version from lspci command. lspci is a command on Unix-like operating systems that prints detailed information about all PCI buses and devices in the system. After that I installed the driver using method 1 which is I explained earlier in that post.

Everything was ok,  I used the internet connection for hours, but after that I encountered a new problem. The wireless was working well but it couldn't see any wireless connections. I thought, I can use error debugging techniques in linux to find the actual problem.

I am going to explain Error debugging techniques in linux at an article in the next days. 

So, I opened a terminal and I typed in:

syslog is a .txt file which includes all errors, messages and notifications coming from apps, softwares etc. And the most beautiful property is we can view at  this moment what is going on about an application or software. Once you typed in above command it will show the new errors or messages too. 
When I typed in that command , and view messages, I clicked the icon at the right bottom of desktop and then >>Connect to Hidden Wireless Network , I choosed an past connection which I used before. And click connect. My purpose was to interact with network manager and see if it has a problem if it is see in the syslog. When I did this I saw an input to syslog which is shown below:

As you see in the last rows, it is saying eth1 is not active.(inactive) We found the actual problem!. Now we are going to solve it.. I typed the following commands into terminal to stop and restart again eth1 interface.

This solved my problem. I hope it solves your problem too..
