The WiFi sometimes connect and most of the time I need to connect the LAN cable, then I am able to connect wifi. However if I remove cable, the wifi is disconnected!! Also, I have to flash the receiver by removing the power cable from socket.
Is there a plugin or fix to have the wifi connected all the time?
