You can't, you need the CD.
you ether need a Nintendo wifi usb connector or a wireless router.
it connects the wii to the internet
If by "install" you mean 'plug it in to a usb port' then, yes. You will have to plug in the wifi usb connector in order to use it If by "install" you are referring to the rigmarole of going through the driver & software installation process, then no. Your computer's operating system will be able to use the wifi connector without having to go through all that software install process ever again.
try eBay

Try placing the ds closer to the usb wifi connector
No, as long as your Nintendo DS can pickup a wireless connection, you can still connect to Nintendo WFC.
