I have had lots of faults and recently got a replacement receiver. This also has the same faults. The other day the picture froze and the receiver rebooted. When I tried to use the WiFi I couldn’t detect any routers. I think that the WiFi module had a fault/possible short. The only way I could get the WiFi to work again was to turn the power off at the socket for minute. My other receiver had the same intermittent fault. Could this be a faulty WiFi module?
