I reboot my units every twelve hours and yes it typically takes about 30 seconds for the to connect to BTCguild. At first I would restart if it did not connect in 12 seconds but I learned to wait a little longer. I have one of my five units that takes about 45 seconds to connect.
I have not found a good solution other than reboot all five one after the other and by the time I am back to check the api log on the first one it's connected. As I work my way one to the next it will be connected, the slow one is the last to check and it is usually connected when I get to it.

Does anybody has problems with connection? In my miner ethernet is unstable and it can't find wifi networks.
Not sure you are mentioning about the same problem.
But i am having some connexion socket problem (Lan)...
Sometimes it takes 30seconds to start, but sometimes i need to restart it, wait, restart, reboot, ... until it connects to my pool (can take up to 20 minutes for the worst case).
I heard about a bug with the NTP and to input 8.8.8.8 but still didn't help...
