254 really... that is the number of allocations of IP addresses available. For any more, you would need additional networking equipment/dhcp server
Router routes traffic to different computers connected to it.
It is connected by a network cable, switch and a router.
You should be able to check how many computers are connected to your router, in the router settings. Most likely you can find it in "Status" for wireless network or for all networks. You check MAC addresses for all your computers connected to the router and compare it with those in the list. In that way you know if you have some "guests". You find out who connected to your router will be much harder and require special software and training.PS: you can use MAC filter to block "guests".
A network bridge just expands the number of computers that can be connected to the router.
They're probably set up to use DHCP to obtain an IP address from the router. It's likely you don't have a working connection to your router. Make sure your switch is connected to the router, and not just the other computers.
It does not require any particular switch or router you can use either.

It has to always be broadcasting radio waves otherwise no devices will ever find the router.
The Belkin can support 255 computers wirelessly, and four wired. Although, with that many connected you would be very much bandwidth starved.
Well, LAN means multiple computers are wired to a router that connects to the internet. So, you would need to place the computers so the Ethernet cord can be connected to the router
No. The purpose of a gaming router is to provide the best possible performance for communication between computers on a LAN. It does not have to be connected to the internet.
Depends on where the printer is located. If you can have it connected to the router, on the router install a print manager. On each computer connected to the router using your LAN, install the printer using the print manager as the target.
