WiFi Connection Problem! I have an an android phone. The problem is that when I connect my phone, which is android Jelly Bean, to my Wi-Fi connection it works and the internet connection doesn't have any issues.

However, when I open my PC the phone loses the connection and no internet is established on the phone, while it works at the same time, very good on the PC and any other phone connected on the Wi-Fi. I hope you help me find the cause. 

I tried to find the issue but I couldn't!
Thanks in Advance
It seems that you have allowed only one device to be connected at a time in your WIFImodem, kindly check that there is an option in your modem of connected devices in which you have selected 1, change it to as maximum as you can and then try
