Hi,
I have similar issues. My Tivo box is connected to the Hub3 via a cat5 cable, the V6 is connected by wireless.
On a daily basis the Hub3 loses the Tivo box and I need restart the Hub3 to regain connectivity, the green activity light on the port shows it's connected and active.
I've tried the Tivo in all the ports. My desktop is also connected via Cat5 and has no problems with connectivity.
Simply restarting the Tivo doesn't help, even after leaving it off for 30 minutes, the Hub3 needs to be restarted.
I suspect the long periods of inactivity with the Tivo boax cause the connection to be lost.
Any advice would be most welcome.
Thanks, Pete.
