I have a problem with my notebook, I can't connect to a WiFi network from my notebook.
It finds all the wireless networks around but it is unable to connect to anyone. I've tried deleting the password of the network and trying to connect without password but it didn't work either. I know that my WiFi network is working because I can connect to it from my smartphone. I also tried pinging 127.0.0.1 and I received the reply. I don't know what to do to make it works, is there something wrong with my network card? I also tried it on Linux and faced the same problem.
