This is a bit tricky. I was tempted to answer "Check whether your wireless is on". However, if you do "View wireless networks" you will not only see
and that makes it faster to connect to the school wireless network
An access point (AP)
This is assuming that there is no outside access to the Ethernet network such as a Internet connection. If there were then firewalls would be needed to prevent a outside intrusion of the network. In addition to physical access security, a wireless network requires authentication and encryption to prevent unauthorized devices from connecting to the wireless network or capturing and decoding the data that is being transferred via a wireless network connection. If the wireless network has outside WAN access then you would also need firewalls as with the Ethernet network.

Wireless bridging is the technique of connecting two wireless access points together. This can be done to extend the range of a wireless network, or to create a wireless bridge between two or more wired networks, perhaps in separate buildings.

No, why would you? I suggest just buying a wireless PCI card for the two desktops. It would make life much more easier. You can, what you need is a wireless router... this will allow you to have approximatly 4 ethernet ports and wireless access to your network, but look in your manual to make sure you encrypt the data so as to protect from wireless predators...
If the printer can connect to the wireless access point via ethernet and that the printer has been enabled to be used on a wireless network then in theory yes.
How do multiple access points identify themselves as part of the same network
Wireless access points are created by installing wireless routers. These routers are providing the opportunity for other devices to get wireless access to a network and or internet.

You will need to add a wireless access point to the wired network.
An SSID is the 'name' for a wireless access point. There's no 'button' for it, but you might mean the option to scan for wireless access points, this is done on the network settings while configuring a network connection on the PSP.
