Recently I ran into some router issue that is a big name. The issue is wider than first reported and the fix is to roll the firmware back a version until this name gets a fix out.
As to the genius issue, this is pretty simple to explain. Folk often don't like why so I'll see if you really want to know.
Occasionally, I wake my Mac from sleep and find I have no internet connection. This is almost always fixed by rebooting the computer and the ethernet router.
Is there a way to determine if this indicates a problem with the router or something happening external to my network? It is not a major nuisance in itself, but since the Mac will be taking over as an over-the-air DVR, and communicates with the tuner by ethernet, reliability of ethernet has become much more important.
The geniuses at Sony who designed my standalone DVR made it utterly dependent on the TV Guide over-the-air service. There is no way for the user to set the date and time, or for the device to acquire this info from any other source. Hard to believe, but true. Rovi, who provides the OTA guide has decided to pull the plug on their North American service, making all such Sony DVRs virtually useless.
