Network Manager does not connect to wireless

[Pookito pookito]

I am a big fan of Elementary OS. Sadly the network manager connects to the wifi and most of the time it does not. The good news is that I downloaded WICD and it works fine, no problem at all. the sad part is that the original app is tight with the app center and the app center does not work without the wireless app that comes the OS. I can no longer download from the app center. I have to use the command line for update and downloads. I ran a few commands that I believe it might help with the bug. Any helpd will be greatly appreciated. I can pay for the fix if needed. I search for the bug similar to mine, but I did not find it.
