Disconnecting after 2 minutes

Everything has worked fine for several years, but in the last two days my Serviio keeps disconnecting after one or two minutes. I have downloaded 1.8 but the problem persists. I have a Samsung tv and wireless connection. Can anyone advise?

Maybe the quality of you wireless connection changed (like a new neighbor using the same channel, big appliance nearby interfering with the signal, etc)
