Factory Reset taking along time

Hello All, I just received a new tablo 2 tuner from Amazon. It worked great until I did a software update right after I set it up. After the software update It would connect fine but no picture was avialable. Now I have done a factory reset in hopes of starting it over and working from there. I held the button down and it has been blinking for the better part of an hour? Does anyone know how long a factory reset should take?

Is your Tablo hard wired to your router?

It is now, I was able to connect back to the tablo and do a scan. It only finds  a handful of channells, with other TV tuners I have been able to get many more. Either way it still wont play anything, it won’t connect to live TV or show a guide.
