All PC's are using Windows XP with SP3. The laptop is using Vista Home Edition.
2 PC's are hard-wired into the router. 1 PC is connected wirelessly (it is upstairs away from the router point). 1 PC is in another room, and the goal is to have it connect wirelessly. The laptop is close to the router..it CAN be wired..but it's preferred to be wireless.
Now, my father ran Network Wizard...and herein come the questions:
1. Is there an issue with cross OS platforms and networking? My somewhat educated guess would be no..that the OSI model Layer 2 and Layer 3 is independant of the OS.
Not when all the operating systems are microsoft, I've got a server 2003 system in my house along with several Vista x64 and XP machines, they all talk to each other.
2. Is there a maximum number of devices that can be supported on this wired/wireless router? I know that speed over the 'net would be affected with multiple devices accessing the net connection, but with it being a 100Mbps switch, networking among the computers shouldn't be an issue, should it?
Supposedly its when you run out of IP Addresses  but my linksys router started having issues maintaining connections (both wired and wireless) when we had about 20 devices pulling IP's on our network... You should be fine with only 4 PC's though.
3. Now, doing this over the phone with my Dad was a tad frustrating, since he just got out of the hospital/rehab after a traumatic injury. So his brain is a tad slow...but I walked him thru checking IP addresses, etc. with each computer. The reason being is that on his main computer that he ran Network Wizard on, he could see his other PC in his office, the other PC that is connected wirelessly from upstairs...but he can't see his laptop (which is Vista)
This is probably an issue with the Vista machines firewall.
and the computer in the library (PC attempting to be wireless). Now, the PC in his library does not show any ip address assigned..so I'm guessing that the wireless card wasn't on, or something wasn't right when Network Wizard ran.
try and take the wireless laptop up next to the machine in the library and make sure the signal is stong enough in that area of the house, it could be that the wi-fi card is getting no signal up there.
His two PC's in his office both have IP addresses, subnet masks, and default gateways. His laptop (the Vista wireless) has an IP address, subnet mask, default gateway. But the PC's in his office can't see the laptop. I "believe" his laptop can see the two PC's, but I'm not sure about that. So, is this a problem due to Vista vs XP?
its gotta be the firewall on the laptop. Make sure file and printer sharing is allowed through the software firewall.
4. Is the network wizard really all cracked up it's meant to be? I mean..the goal is to allow file transfers between his laptop and two office PCs...and to gain access to a color printer upstairs on the PC wirelessly connect there...and for it to print to the laser printer downstairs if need-be.
network wizards can be flaky... as for the printing, good luck, I ended up buying a network printer because of issues caused by trying to share a local printer on one machine with other systems running different versions of windows.
I know...I know too much to be dangerous, and probably not quite enough to have all answers lol...
it all comes in time every problem is a learning experience.
