Does anyone know why this keeps happening? Today I get a warning that the Guide data will run out in five days. I checked the network connection (hard wired Ethernet) and it says the last attempt was successful. I tested it and the test ran fine. I forced a connection and it reported it was successful as well but the guide info is still not updated.
I recalled a similar issue on a older series 2 I had a few years ago. Also searching on the Web I found reports of this dating back 5 or 6 years. I was able to easily fix it by doing a hard reset (pulling power cord) and rebooting. After the reboot, bam the guide was updated instantly with usual 2 weeks of data, no net connection was necessary so obviously the Tivo had the info but just refused to display it or schedule recordings. If hadn't noticed this I would have started loosing recordings in a few days.
It is an admittedly rare issue, but why is this still happening after all these years? That's a long time for a bug to remain lurking around IMHO.
