Yes you need to own a wireless router or something that gives off a wireless internet signal for it to work
No. You need a wireless router, though you don't necessarily need a computer.

Wireless broadband works for newer computers. Depending on how many wireless devices you need to use at the same time will be the deciding factor in how well your broadband service works.
Yes, as long as it has wireless broadband.
Yes, it will you get driver for your adapter from the adapter's manufacture website.

No unless a neighbor has internet which then it has to be unlocked or you have to get the wireless network's password.
The converter adapter allows PS2 controllers to work with the PS3 or a PC.It probably wouldn't work on a wireless controller.
Have you been searching for a way to install a mobile broadband wireless router on your older computer system? You might need to find a driver file that would allow the device to work with the operating system that you are using. Not all routers will work with old systems.
Yes
You need to buy a cable wireless router, Once you have that, Keep your cable modem hooked up to the broadband cable, Plug the ethernet cable from the cable modem to the wireless rouer, And that should work.
I am not going to say it is impossible for a different adapter to work, just unlikely . The Xbox 360 Wireless Network Adapter was made specifically for that purpose, so it is unlikely that a normal adapter will work if attached to the Xbox as they most likely will not be compatible.
