Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
The updating of the Fiery either
A. was improperly and inadequately applied and needs for you to try to apply it completely and rightly - matching the model # ***** for one thing, if it was an update you chose, rather than an update it chose for itself.
B. the update somehow wiped out the parameters of configuration to your network in the Fiery, and it needs to be set-up from scratch as if it were new from the factory.
As for the driver - what is the operating system or Windows version on your computer, that you wish to install the proper driver upon?
If the Fiery is the interface to the network for the BizHub, then of course it's off the network.
Did the Fiery update itself, or did you update it manually?
I regret that I am not in a position to offer Live Phone Service at this time.
I am unfortunately out of ideas on this case, so I should Opt Out, and have done so. I will still be able to see and respond to further postings, but have opened the case to others in case another Expert can help you better.
