Background information: complete beginner installing NIS 2009 from CD (then running LiveUpdate after initial attempt to connect to internet through Charter Cable) on a single XP SP3 computer (no network) with no previously installed security software (it's been in storage and not used) which is to be connected to a USB Canon Pixma printer (5 years old but never used) and later to a new wired router (brand unknown at this point).
I understand there can be problems with the NIS firewall when connecting devices such as printers and routers, so in order to be prepared, my questions are:
1. Is it generally better to have the printer already connected and working before installing NIS 2009 as above? Or, to wait until after running LiveUpdate, then temporarily disable the firewall (I hope that's pretty straightforward), and then connect the printer?
2. By the time I research and purchase a wired router, most likely NIS 2009 will be installed. That being the case, what is the best procedure when connecting the router? What are the issues, and where do I go to solve problems if any arise?
3. Soon after installing NIS 2009 I will attempt to upgrade to NIS 2010. How will that affect this situation? Should I leave the printer and router connected while attempting to upgrade to NIS 2010?
Thanks in advance. I've just never done any of this before and am trying to be as prepared as possible.
