My system suddenly stopped receiving data from the ISS overnight so I suspected a low 3v battery which I changed. Still no data on the display so I tried rebooting and went through the AP to check the IP on my network. I receive signals directly to the MB but I then realised that my Console was receiving data on it's display. I altered the Console to redirect the data as well as changing the setting on MB - still nothing being sent to the internet. I did notice however that the RAM was running at 86% and wondered if this could be the issue? Can the RAM usage be reduced I wonder or is this a standard value? Any other ideas would be welcome please.
